SAFETY NOTICE: IF YOUR ENCORE IS NOT PROP-

ERLY INSTALLED, A HOUSE FIRE MAY RESULT.

TO REDUCE THE RISK OF FIRE, FOLLOW THE

INSTALLATION INSTRUCTIONS. CONTACT LOCAL

BUILDING OR FIRE OFFICIALS ABOUT RESTRIC-

TIONS AND INSTALLATION INSPECTION REQUIRE-

MENTS IN YOUR AREA.

In some modern, super-insulated homes, there is

inadequate air for combustion because of insufﬁcient

air inﬁltration into the building. Such air enters a home

through unsealed cracks and openings. Exhaust fans

for kitchen or bath can compete with the stove for avail-

able air and compound the problem.

Before you begin an installation, be sure that:

When poor draft is caused by a low inﬁltration rate,

opening a ground ﬂoor window on the windward side

of the house and in the vicinity of the stove will usually

alleviate the problem.

• Your stove and chimney connector will be far

enough from combustible materials to meet all

clearance requirements.

• The ﬂoor protector is large enough and is con-

structed properly to meet all requirements.

For appliances with power outputs above 5 kW, a

permanently open air vent is required by Section 2 of

Document J. Air inlet grilles should be positioned so

that they will not be blocked. Refer to local and national

codes for recommended conﬁgurations.

• You have all necessary permits from local au-

thorities.

Your local building ofﬁcial is the ﬁnal authority for ap-

proving your installation as safe and determining that it

meets local and state codes.

The metal label permanently attached to the back of

every Vermont Castings’ stove indicates the stove has

been tested to current standards. The test standard

is EN13240:2001 + A2:2004 for Europe. Clearance

and installation information also is printed on the label.

When the stove is installed according to the information

both on the label and in this manual, local authorities

in most cases will accept the label as evidence that the

installation meets codes and can be approved.

Pressure variations within the house do not affect a

stove equipped with an outside air supply, and im-

proved stove performance often results. An Outside Air

Adapter Kit for the Encore is available from your local

Vermont Castings dealer.

Chimney Height

Altitude affects chimney performance. When using a

6” ﬂue collar on the Encore, refer to Figure 2 for sug-

gested chimney heights at various altitudes. Chimney

height should be measured from the ﬂue collar to the

top of the chimney. The recommended minimum chim-

ney height is 4.9 m (16’).

However, codes vary in different countries. Before

starting the installation, review your plans with the local

building authority. Your local dealer can provide any ad-

ditional information needed.

Encore Woodburning Stove

What Kind of Chimney to Use

Prefabricated Chimneys

You must connect the Encore to a code-approved

masonry chimney with a ﬂue liner, to a relined masonry

chimney that meets local codes, or to a prefabricated

metal chimney. (Fig. 3) The chimney and chimney con-

nector must be in good condition and kept clean.

If you use an existing masonry chimney, it must be

inspected to ensure it is in a safe condition before the

stove is installed. Your local professional chimney

sweep, building inspector, or ﬁre department ofﬁcial will

be able to inspect the chimney or provide a referral to

someone who can.

These should be an internal diameter of 150 mm (6”)

and be of the twin wall insulated construction that has

been approved for solid fuel use (e.g. Rite Vent ICS of

ICID Lite Chimney Systems). Diameters over 200 mm

(8”) are not recommended due to the large cross-sec-

tion causing excessive cooling of the ﬂue gases.

DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE

SERVING ANOTHER APPLIANCE.

Chimney Size

An Encore with an 203 mm (8”) ﬂue collar is approved

for venting into a masonry chimney with a nominal ﬂue

size of 203 x 203 mm (8” x 8”) or 203 x 305 mm ( 8”

x 12”), and into a round ﬂue with nominal ﬂue size of

203 mm (8”). An Encore with a 152 mm (6”) ﬂue collar

is approved for venting into a masonry chimney with a

nominal ﬂue size of 203 x 203 mm (8” x 8”), and into a

round ﬂue with nominal ﬂue of 152 mm (6”).

The ﬂue and chimney design must meet requirement

J2, Part J of the building regulations 2000 (Combustion

Appliances and Fuel Storage Systems).

A prefabricated double-

wall insulated chimney

NOTE: When installed with a 6” ﬂue collar, the

Encore may not be operated with the front doors

open.

Whatever the ﬂue collar size, an Encore may be vented

into larger chimneys as well. However, chimneys

with liners larger than 203 x 305 mm (8” x 12”) may

experience rapid cooling of smoke and reduction in

draft, especially if the chimneys are located outside the

home. These large chimneys may need to be insulated

or have their ﬂues relined for proper stove performance.

masonry

chimney

ST241

Fig. 3 Approved chimney types.

Accessories to help make the connection between

stainless steel chimney liners and your Encore are

available through your local dealer.

Masonry Chimneys

An inspection of the chimney must conﬁrm that it has

a lining. Do not use an unlined chimney. The chimney

should have no cracks, loose mortar, other signs of

deterioration, and blockage. Repair any defects before

the chimney is used with your stove.

Chimney Connector Guidelines

A chimney connector is the double-wall or single-wall

pipe that connects the stove to the chimney. The chim-

ney itself is the masonry or prefabricated structure that

encloses the ﬂue. Chimney connectors are used only to

connect the stove to the chimney, as in Figure 5.

Unused openings in an existing masonry chimney must

be sealed with masonry to the thickness of the chimney

wall, and the chimney liner should be repaired. Open-

ings sealed with pie plates or wallpaper are a hazard

and should be sealed with mortar or refractory cement.

In the event of a chimney ﬁre, ﬂames and smoke may

be forced out of these unused thimbles.

Connecting Flue Pipes

Connector pipes should meet the requirements of the

building regulations. This can be achieved by the use

connecting ﬂuepipes included in the following catego-

ries:

The chimney should be thoroughly cleaned before use.

a) Vitreous enamelled steel pipe complying with BS

6999: 1989 (1996);

A newly-built masonry chimney must conform to the

standards of your local building code or, in the absence

of a local code, to a recognized national code. Masonry

chimneys must be lined, either with code-approved

masonry or pre-cast refractory tiles, stainless steel

pipe, or a code-approved, “poured-in-place” liner. The

chimney’s clean-out door must seal tightly.

b) Pipes made from stainless steel as descirbed in BS

EN 1008-1:1995 grades 1.4401, 1.4404, 1.4432 or

1.4436 with ﬂue wall thickness of at least 1 mm;

c) Mild steel ﬂuepipes complying with BS 1449: Part 1:

1991, with a ﬂue wall thickness of at least 3 mm;

d) Cast iron ﬂuepipes complying with BS 41: 1973

(1998).

Encore Woodburning Stove

Flue Pipes with a spigot and socket joint should be

ﬁtted with the socket facing upwards, to contain con-

densates and moisture within the ﬂue. Joints should be

made gas tight using proprietary jointing accessories,

or, where appropriate, by packing joint with noncombus-

tible rope and ﬁre cement.

Single-wall Chimney Connectors

• Begin assembly at the ﬂue collar of the stove. Insert

the ﬁrst crimped end into the stove’s ﬂue collar, and

keep each crimped end pointing toward the stove.

(Fig. 4) Using the holes in the ﬂue collar as guides,

drill 3 mm (1/8”) holes in the bottom of the ﬁrst sec-

tion of chimney connector and secure it to the ﬂue

collar with three #10 x 1/2” sheet metal screws.

Double-wall connectors must be tested and listed for

use with solid-fuel burning appliances. Single-wall con-

nectors should be made of 24 gauge or heavier steel.

Do not use galvanized connector; it cannot withstand

the high temperatures that can be reached by smoke

and exhaust gases, and may release toxic fumes under

high heat. The connector may be 152 mm (6”) or 203

mm (8”) in diameter.

• Secure each joint between sections of chimney

connector, including

telescoping joints, with at

least three (3) sheet metal

screws. The pre-drilled

holes in the top of each

section of chimney con-

nector serve as guides

when you drill 3 mm (1/8)

holes in the bottom of the

next section.

If possible, do not pass the chimney connector through

a combustible wall or ceiling. If passage through a com-

bustible wall is unavoidable, refer to the section on Wall

Pass-Throughs. Do not pass the connector through an

attic, a closet or similar concealed space. The whole

connector should be exposed and accessible for in-

spection and cleaning.

• Secure the chimney con-

nector to the chimney.

Instructions for various

installations follow.

In horizontal runs of chimney connector, maintain a dis-

tance of 610 mm (24”) from the ceiling. Keep it as short

and direct as possible, with no more than two 90° turns.

Slope horizontal runs of connector upward 6 mm per

metere (1/4” per foot) going from the stove toward the

chimney. The recommended maximum length of a hori-

zontal run is 914 mm (36”), and the total length should

be no longer than 2.4 m (8’). In cathedral ceiling instal-

lations, extend the prefabricated chimney downward to

within 2.4 m (8’) of the stove.

• Be sure the installed stove

and chimney connector are correct distances from

nearby combustible materials.

NOTE: Special slip pipes and thimble sleeves that form

telescoping joints between sections of chimney con-

nector are available to simplify installations. They often

eliminate the need to cut individual connector sections.

Consult your local dealer about these special pieces.

Wear gloves and protective eyewear when drilling,

cutting or joining sections of chimney connector.

Securing the Single-wall Connector to a

Prefabricated Chimney

Double-wall Chimney Connectors

Follow the installation instructions of the chimney

manufacturer exactly as you install the chimney. The

manufacturer of the chimney will supply the acces-

sories to support the chimney, either from the roof of

the house, at the ceiling of the room where the stove is

installed, or from an exterior wall.

Information on assembling and installing double-wall

connectors is provided by the manufacturer of the

double-wall pipe. Follow the manufacturer’s instructions

exactly as you assemble the connector and attach it to

the stove and chimney. Using chimneys and connectors

from the same manufacturer makes the assembly and

installation straightforward.

Special adapters are available from your local dealer

to make the connection between the prefabricated

chimney and the chimney connector. The top of such

adapters attaches directly to the chimney or to the

chimney’s ceiling support package, while the bottom of

the adapter is screwed to the chimney connector.

NOTE: For installations using double-wall connectors,

minimum clearances must conform to the listed clear-

ances in the clearance chart on Page 14.

If the Encore is equipped with the 203 mm (8”) ﬂue

collar, an oval-to-round adapter will be needed. Double-

wall oval-to-round adapters are available from some

manufacturers. Your local dealer can help you select

the right connector.

These adapters are designed so the top end will ﬁt

outside the inner wall of the chimney, and the bottom

end will ﬁt inside the ﬁrst section of chimney connector.

When assembled in this way, any soot or creosote fall-

ing from the inner walls of the chimney will stay inside

the chimney connector.

Masonry Chimney

Fireplace Installations

Both freestanding masonry chimneys and ﬁreplace

masonry chimneys may be used for your installation.

The chimney connector may be connected to the

chimney above the ﬁreplace opening or through the

ﬁreplace.

Freestanding Installations

If the chimney connector must pass through a combus-

tible wall to reach the chimney, follow the recommenda-

tions in the Wall Pass-Through section that follows.

Above the Fireplace

The Encore may be connected to a chimney above

a ﬁreplace opening. (Fig. 7) In such installations, the

stove is positioned on the hearth in front of the ﬁreplace

and the chimney connector rises from the stove top and

then angles ninety degrees back into the chimney. The

chimney liner should extend to the point at which the

chimney connector enters the chimney.

The opening through the chimney wall to the ﬂue

(the “breech”) must be lined with either a ceramic or

metal cylinder, called the “thimble”, which is cemented

securely in place. Most chimney breeches incorporate

thimbles, but the ﬁt must be snug and the joint between

the thimble and the chimney wall must be cemented

ﬁrmly.

If the chimney connector from your installation enters

the chimney above a ﬁreplace, follow all the guidelines

mentioned above for freestanding installations. In addi-

tion, give special consideration to the following points:

A special piece called the “thimble sleeve,” slightly

smaller in diameter than standard connectors and

most thimbles, will facilitate the removal of the chimney

connector system for inspection and cleaning. Thimble

sleeves should be available from your local dealer.

• Check the clearance between the stove and the

chimney connector, and any combustible trim or the

mantel. Use the necessary combination of mantel, trim,

and connector heat shields to achieve the required

clearances.

To install a thimble sleeve, slide it into the breech until

it is ﬂush with the inner ﬂue wall. Do not extend it into

the actual ﬂue passage, as this could interfere with the

draft.

• Check the clearance between the chimney con-

nector and the ceiling. If no heat shields are used, the

clearance should be at least 610 mm (24”). To ﬁnd out

how much this clearance may be reduced with heat

shields, refer to the clearance chart on Page 12.

Figure 9 shows one method of passing a connector

through a wall. All combustible material in the wall is cut

away to provide the required 457 mm (18”) clearance

for the connector. The resulting space must remain

empty. A ﬂush-mounted sheet metal cover may be used

on one side only. If covers must be used on both sides,

each cover must be mounted on noncombustible spac-

ers at least 25 mm (1”) clear of the wall.

Through the Fireplace

If your ﬁreplace opening height is at least 675 mm (26¹⁄₂"),

you may install an Encore through the opening using a

“positive connection” kit, available from your local dealer.

These positive connection kits ensure a tight ﬁt between

the stove ﬂue collar and the chimney ﬂue. (Fig. 8)

Your local dealer or your local building inspector can

provide details for other approved methods of passing

a chimney connector through a combustible wall in your

area.

DO NOT CONNECT AN ENCORE TO ANY AIR DIS-

TRIBUTION DUCT OR SYSTEM.

Fireplace installations, whether connected to the ﬂue

above or through the ﬁreplace opening, have special

clearance requirements to adjacent trim and the mantel.

Wall Pass-Throughs

Whenever possible, design your installation so the con-

nector does not pass through a combustible wall. If you

are considering a wall pass-through in your installation,

check with your building inspector before you begin.

Also, check with the chimney connector manufacturer

for any speciﬁc requirements.

Accessories are available for use as wall pass-

throughs. If using one of these, make sure it has been

tested and listed for use as a wall pass-through.

Encore Woodburning Stove

Hearths

This appliance must be installed on to hearth that

meets the requirements of Part J of the Building Regu-

lations 2000 (Combustion Appliances and Fuel Storage

Systems). This can be achieved by ensuring that the

hearth is constructed and sized in accordance with the

guidelines included in section 2 of approved document

‘J’. The size and clearances of the hearth are as fol-

lows:

The constructed hearth should be constructed in ac-

cordance with the recommendations in document J,

and should be of minimum width 840 mm and minimum

depth 840 mm (if a free standing hearth b) above) or

a minimum projection of 150 mm from the jamb (if a

recessed hearth a) above).

Floor Protection for Fireplace Installations

Do not assume that your ﬁreplace hearth is completely

noncombustible.

Keep the Stove a Safe Distance

from Surrounding Materials

Many ﬁreplace hearths do not meet the “completely

noncombustible” requirement because the brick or

concrete in front of the ﬁreplace opening is supported

by heavy wood framing. (Fig. 11) Because heat passes

through brick or concrete readily, it can easily pass

through to the wood. As a result, such ﬁreplace hearths

can be a ﬁre hazard and are considered a combustible

ﬂoor.

Both a stove and its chimney connector radiate heat in

all directions when operating, and dangerous overheat-

ing of nearby combustible materials can occur if they

are too close to the heat. A safe installation requires

that adequate clearance be maintained between the

hot stove and its connector and nearby combustibles.

Clearance is the distance between either your stove

(measured from the bottom edge of the stove’s top

plate) or chimney connector, and nearby walls, ﬂoors,

the ceiling, and any other ﬁxed combustible surface.

Your stove has special clearance requirements that

have been established after careful research and test-

ing to both US and European standards. These clear-

Keep in mind, also, that many raised hearths will extend

less than the required clearance from the front of the

heater when it is installed. In such cases, sufﬁcient

ﬂoor protection as described above must be added in

front of the hearth to satisfy the minimum ﬂoor protector

requirement from the front of the stove: 406 mm (16”)

from the front.

In addition, furnishings and other combustible materials

must be kept away from the stove as well. In general, a

distance of 1219 mm (48”) must be maintained between

the stove and moveable combustible items such as dry-

ing clothes, furniture, newspapers, ﬁrewood, etc. Keep-

Safe Ways to Reduce Clearances

Clearances

As with any solid fuel heating stove, extremely high

surface temperatures can occur, particularly in the

event of uncontrolled operation, e.g. if the doors

are inadvertently left open. It is crucial that suf-

ﬁcient clearances are allowed to any combustible

surfaces, e.g. wooden mantels or lintels, and to

timber framed (studded) walls even if they are faced

with noncombustible board. Detailed information

on ﬁreplace and hearth construction is provided

in section 2 of Document J, all installations must

comply with these requirements or with the relevant

National or local building standards.

ST486a

Fig. 12 Minimum clearances.

Connecting Flue Pipe - Clearances

Single wall connecting ﬂuepipes can reach extremely

high temperatures; therefore, clearances from the con-

necting ﬂuepipe (chimney connector) must comply with

the requirements of Part J of Building Regulations 2000

(Combustion Appliances and Fuel Storage Systems).

This can be achieved by following the recommenda-

tions of Approved Document ‘J’. These are as shown in

Figure 13.

Clearances to timber framed (studded) walls are in-

cluded below. There are no speciﬁc minimum clearanc-

es to solid noncombustible surfaces (e.g. the sides and

rear of Inglenook ﬁre openings constructed from solid

masonry) other than to allow safe access to the controls

of the stove. For this reason minimum side clearances

of 125 mm, and a minimum rear clearance of 50 mm

are recommended.

Summary of Clearances

Minimum recommended side clearances to non-

combustible surfaces 125 mm (5”).

Minimum recommended rear clearance to noncom-

bustible surfaces 50 mm (2”).

NOTE: The minimum thickness of solid noncombustible

materials is speciﬁed in section 2 of Document ‘J’, in

relation to the clearance of the appliance from the sur-

face. As a general rule, the thickness of solid noncom-

bustible material forming the recess of a ﬁreplace is a

minimum of 200 mm.

Minimum rear clearance from combustible walls

(e.g. timber framed or studded walls) 1000 mm

(39³⁄₈”) measured from the rear edge of the stove

top. (Fig. 12, B)

Install the Optional Bottom Heat Shield

NOTE: The Bottom Heat Shield is required in most in-

stallations. Refer to Floor Protection, Page 9, for further

details. The bottom heat shield comes with the ash pan

heat shield.

1. Remove the four 10-24 x 1/2” hex head bolts from

the corners of the ash drop on the stove bottom.

2. Screw the four (4) 1¹⁄₄" spacers into the holes from

4. Secure the shield with the four (4) hex head bolts

removed from the stove bottom previously.

The primary air thermostat handle is the smaller of the

two black handles. Secure the handle to the stub on

the right side of the stove with an 8-32 x 2” slot head

machine screw.

5. Tighten securely.

Attach the Damper Handle

Use the 1/4” -20 x 3” screw to attach the damper handle

to the damper stub on the left side.

Assemble the Removable Insert Handle

The white removable insert handle opens and closes the

front doors. Remove after each use so it won’t get hot.

Store it in the handle holder installed behind the right

front leg. Assemble the handle by passing the 86 mm

(3³⁄₈") screw through the ceramic shaft and into the bright

metal nub. Tighten carefully until snug.

Operation

For the greatest air supply and maximum heat output

(but the shortest burn time), move the lever toward the

front of the stove. For a ﬁre that will last longer with less

heat, move the lever toward the rear of the stove.

The Encore Controls

Two controls regulate the performance of the Encore: a

primary air control supplies oxygen for the ﬁre, and a

damper directs air ﬂow within the stove to activate and

deactivate the catalytic combustor.

The Encore’s air control system also features an

automatic thermostat to ensure an even heat output

at whatever manual setting you select. The thermostat

senses the heating and cooling of the stove surface

and adjusts the air shutter accordingly.

Symbols cast into the stove are reminders of the correct

directions for opening and closing the controls. The

symbols assume that you are facing the front of the

stove.

A Single Air Control Regulates

Heat Output and Burn Time

The damper handle on the left side of the stove opens

and closes the damper to direct air ﬂow within the

stove.

The primary air control lever, located on the right side

of the stove, controls the amount of incoming air for

starting, maintaining, and reviving a ﬁre.

The damper is open when the handle points to the

back of the stove, enabling smoke to pass directly into

the chimney. The damper must be open when starting

or reviving a ﬁre, and whenever the griddle or doors are

opened.

More air entering the stove makes the ﬁre burn hotter

and faster, while less air prolongs the burn at a lower

heat level. High and low settings appear in Figure 20.

The damper is closed when the handle points forward.

Smoke from the ﬁre is directed through the catalytic

combustion system where it can be further burned for

greater efﬁciency, before passing up the chimney.

To reduce the risk of breaking the glass, avoid striking

the glass or slamming the doors.

When not using the door handle, store it in the holder

behind the right front leg of the stove.

When closing the damper, be sure to pull ﬁrmly

Infrared Reﬂective Glass Panels

for Clear Fire Viewing

Two Ways to Add Fuel

The Encore’s griddle lifts for convenient top-loading of

logs, and is the easiest way to regularly add fuel.

The inner surfaces of the infrared reﬂective glass

panels are kept at a higher temperature than the outer

surface. This design, along with a preheated ‘airwash,’

makes clear ﬁre viewing possible at most levels of

operation.

In addition, however, the front doors open for adding an

occasional log to a ﬁre. The Encore is not approved

in Europe for operation with the front doors open.

To open the front doors, insert the handle into the door

latch stub and turn it to the left and up. (Fig. 23)

Andirons Help Protect the Glass

Your stove has andirons to keep logs away from the

glass panels. The andirons are essential to maintain

clear ﬁreviewing, and should be left permanently in

place. Since the andirons may slightly hinder refueling

through the front doors, most stove owners will prefer

the convenience of top loading through the griddle.

Handle

Quadrants

Burn Only High-Quality Wood

The Encore is designed to burn natural wood only; do

not burn fuels other than that for which it was designed.

You’ll enjoy the best results when burning wood that

has been adequately air-dried. Avoid burning “green”

wood that has not been properly seasoned, or cord-

wood dried more than two years. Do not burn con-

struction materials; they often contain chemicals and

metals that can damage the catalytic combustor. The

wood should be 400-500 mm (18-20”) in length.

ST639

Fig. 22 the Encore’s hinged griddle makes it easy to top-load

wood.

To close them, always close the left door ﬁrst. Turn the

handle in the right door to the left and up (to the open

position) and close it. Finally, push on the door as you

turn the handle to the right and down. The doors will

draw in slightly, and the handle should offer some resis-

tance as you turn it to the closed position.

The best hardwood fuels include oak, maple, beech,

ash, and hickory that has been split, stacked, and air-

dried outside under cover for at least one year.

If hardwood is not available, you can burn softwoods

which include tamarack, yellow pine, white pine, East-

ern red cedar, ﬁr, and redwood. These too should be

properly dried.

Encore Woodburning Stove

Store wood under cover to keep it dry. The longer it is

stored, the better heating and ﬁreviewing performance

you will enjoy. Even for short-term storage, however,

keep wood a safe distance from the heater and keep

it out of the areas around the heater used for refueling

and ash removal.

The control setting also depends on your particular

installation’s “draft,” or the force that moves air from the

stove up through the chimney. Draft is affected by such

things as the length, type, and location of the chimney,

local geography, nearby obstructions, and other factors.

Refer to Page 23 for details on how the installation af-

fects performance.

A Surface Thermometer is a

Valuable Guide to Operation

Too much draft may cause excessive temperatures in

the Encore, and could even damage the combustor.

On the other hand, too little draft can cause backpufﬁng

into the room and/or the “plugging” of the chimney or

combustor.

An optional surface thermometer lets you know when

to adjust the air control, when to refuel, and when your

catalyst is operating properly. (Fig. 24)

How do you know if your draft is excessively high or

low? Symptoms of too much draft include an uncontrol-

lable burn or a glowing-red stove part. A sign of inad-

equate draft is smoke leaking into the room through the

stove or chimney connector joints, low heat, and dirty

glass.

ST523

In some newer homes that are well-insulated and

weather-tight, poor draft may result from insufﬁcient air

in the house. In such instances, an open window near

the stove on the windward side of the house will provide

the fresh air needed.

Fig. 24 Take temperature readings with the thermometer

located in the middle of the griddle.

For example, when the thermometer registers at least

230° C (450° F) after start-up you know the stove is

hot enough to begin catalytic combustion and it may

be time to close the damper. Note that the stove will

warm up much sooner than the chimney, though; a

warm chimney is the key to easy, effective stove opera-

tion. Please review the draft management information

on Page 23 to see how the size, type, and location of

your chimney will affect your stove operation. When

thermometer readings drop below 175° C (350° F) it’s

time to adjust the air control for a higher burn rate or to

reload the stove. A temperature reading over 385° C

(750° F) is a sign to cut back on the air supply to slow

the burn rate.

In some areas provisions for outside combustion air

are required. Refer to section 2 of Document J which

requires an outside air vent for appliances with power

outputs over 5 kW. Always refer to national and local

codes to determine your speciﬁc requirements.

Your Encore will accept a duct to deliver outside air for

combustion.

When ﬁrst using the stove, keep track of the air control

settings. You will quickly ﬁnd that a speciﬁc setting will

give you a ﬁxed amount of heat. It may take a week or

two to determine the amount of heat and the length of

burn you should expect from various settings.

Use the following temperature ranges as a guide to

operation:

Most installations do not require a large amount of

combustion air, especially if adequate draft is available.

Do not for any reason attempt to increase the ﬁring

of your heater by altering the air control adjustment

range outlined in these directions.

• Readings in the 175-260° C (350-500° F) range

indicate low to medium heat output.

• 260-315° C (500-600° F) readings indicate me-

dium heat output.

Use the following air control settings as a starting point

to help determine the best settings for your installation.

Each is described as a fraction of the total distance the

lever may be moved from right to left.

• Readings of 315-400° C (600-750° F) indicate

high heat output. Operating your Encore continuously at

griddle temperatures of 385° C (750° F) or higher may

damage the cast iron or enamel ﬁnish.

Encore Woodburning Stove

To determine whether the combustor is operating, ob-

serve the amount of smoke leaving the chimney when

the damper is activated and when it is not. This proce-

dure is described on Page 27.

High-Efﬁciency Wood Burning with

Catalytic Combustion

An Encore leaves the factory with the combustor in-

stalled.

Avoid using a full charge of very dry wood in the ﬁre-

box. This may result in continuous very high tempera-

tures in the secondary combustion area and damage

the combustor. Wood which has been split, and stored

under cover for more than 18 months may be consid-

ered very dry. Also, do not use a full load of dry slab

wood or scrap wood. For long burns, use a mix of dry

and moderately dry wood.

In the United States, it is against the law to operate this

wood heater in a manner inconsistent with operating

instructions in this manual, or if the catalytic combustor

is deactivated or removed. The components of the cata-

lytic combustion system in your Encore work together to

produce optimum conditions for secondary combustion.

When the damper is closed, smoke travels through

the catalytic element, which causes ignition of smoke

at temperatures of 260-315° C (500-600° F), half the

temperature normally required for unaided secondary

combustion.

Conditioning Your Stove

Cast iron is extremely strong, but it can be broken with

a sharp blow from a hammer or from the thermal shock

of rapid and extreme temperature change.

The catalytic element is a ceramic “honeycomb” coated

with the catalytic material. The element is located in the

secondary combustion chamber, molded from a special

high-temperature insulating refractory material. The

chamber provides the correct environment necessary

for secondary combustion of the fuel (smoke).

The cast plates expand and contract with changes in

temperature. When you ﬁrst begin using your Encore,

minimize thermal stress by allowing the plates to adjust

gradually during three or four initial break-in ﬁres follow-

ing Steps 1-3 below.

Closing the damper exposes the smoke to the combus-

tor. If the combustor is at least 316° C (600° F), it will

begin to burn the smoke.

Starting and Maintaining a Wood Fire

Burn only solid wood in the Encore, and burn it directly

on the grate. Do not elevate the fuel. Do not burn coal

or other fuels.

Closing the stove damper may also reduce the draft,

so to avoid putting out the ﬁre or deactivating the

combustor, close the damper only when a ﬁre is well-

established. When starting a ﬁre, wait until the ﬁre is

well established and there is an ember bed of at least

76-102 mm (3-4”) before closing the damper.

The damper must be open when starting a ﬁre or

when refueling.

Do not use chemicals or ﬂuids to start the ﬁre. Do

not burn garbage or ﬂammable ﬂuids such as gaso-

line, naptha, or engine oil.

Never kindle a ﬁre with colored paper or paper that

has colored ink or a glossy surface, and never burn

treated wood, garbage, solvents, or trash. All of these

may poison the catalyst and prevent it from operating

properly. Never burn cardboard or loose paper except

for kindling purposes. Never burn coal; doing so can

produce soot or large ﬂakes of char or ﬂy ash that can

coat the combustor and cause smoke to spill into the

room. Coal smoke also can poison the catalyst so that it

won’t operate properly.

1. Open the stove damper, and open the primary air

control fully.

2. Place several sheets of crumpled newspaper in the

stove. DO NOT use glossy advertisements or col-

ored paper, as they can poison the catalyst. Place

on the paper six or eight pieces of dry kindling split

to a ﬁnger-width size, and on the kindling lay two or

three larger sticks of split dry wood approximately

25-51 mm (1-2”) in diameter.

In general, the ﬁre must be sufﬁciently well-established

to ensure that catalytic activity is initiated. When ﬁrst

starting a ﬁre, a medium- to high- ﬁring rate must be

maintained until the stove, catalyst, and fuel are all

stabilized at the proper operating temperatures.

Even though it is possible for the ﬁre to get quite hot

within a few minutes after a ﬁre is started, the combus-

tor may stop working or the ﬁre may go out if the ﬁre

is allowed to die down immediately as a result of the

damper being closed. Once the combustor starts work-

ing, heat generated by burning the smoke will keep it

working.

Encore Woodburning Stove

NOTE: Stove installations vary, and the operating

guidance given here is only a starting point. The draft

management information on Page 25 will explain in

detail how the features of your installation may help or

hinder good draft.

Never use gasoline-type lantern fuel, kerosene, char-

coal lighter ﬂuid, or similar liquids to start or “freshen

up” a ﬁre. Keep all such liquids well away from the

Encore while it is in use.

3. Light the newspaper and close the door. Gradually

build up the ﬁre by adding a few 76-127mm (3-5”) di-

ameter splits. If this is one of the ﬁrst few “break-in”

ﬁres, let the ﬁre burn brightly, and then let it die out.

During the break-in ﬁres, do not let the stove get hot-

ter than 260° C (500° F) as measured on an optional

stove-top thermometer. Adjust the air control lever as

necessary to control the ﬁre.

Refuel While the Embers Are Still Hot

When reloading, best results will be achieved if you ﬁrst

de-ash the stove by stirring the fuel bed to allow ash to

fall through the grate into the ash pan.

Do not break the charcoal into very small pieces or

pound or compress the charcoal bed.

It is important that air can circulate through the charcoal

bed during the burn. Larger pieces of charcoal allow

more air to circulate under the wood, resulting in the

ﬁre reviving more quickly.

Some odor from the stove’s hot metal, the paint, and

the cement is normal for the ﬁrst few ﬁres.

NOTE: Some chimneys need to be “primed,” or

warmed up, before they will draw sufﬁciently to start

a ﬁre. To correct this situation, roll up a couple pieces

of newspaper, place them on top of the kindling and

toward the back of the stove, light them, and close

the doors. This will encourage smoke to rise rapidly,

encouraging a good draft.

Once the draft is established, open the front door and

light the rest of the fuel from the bottom. Do not light

the main bed of fuel until the chimney begins drawing,

and repeat the procedure as often as necessary if the

initial attempt is unsuccessful.

ST264a

4. If your Encore has been broken-in previously using

Steps 1-3, continue to build the ﬁre gradually. Add

larger wood with a diameter of 76-102 mm (3-4”).

Continue adding split logs of this size to the briskly-

burning ﬁre until there is a glowing ember bed at

least 76 mm (3”) deep. A good ember bed is neces-

sary for proper functioning of the catalytic system

and may take an hour or more to establish.

Fig. 27 Add full-size logs when the kindling has burned down

to a bed of embers.

For best results when refueling, wear stove gloves to

protect your hands, add fuel while the stove still has

plenty of glowing embers to re-kindle the ﬁre, and

include some smaller pieces of wood in the new fuel

load to help the stove regain its operating temperature

quickly. Use this sequence as a guide to successful

refueling.

NOTE: Door handles can be hot. A glove has been in-

cluded with your stove.We recommend using this glove

whenver operating door or damper controls and espe-

cially when operating the top griddle.

1. Open the damper.

2. De-ash the stove as described above. Open the

front doors and check the level of ash in the ash

pan. Empty the pan if necessary and replace it in the

stove. Close the front doors.

3. Open the griddle, load the wood (smaller pieces

ﬁrst), and close the griddle.

fresh fuel (smaller pieces ﬁrst), close the door and

damper, and reset the primary air thermostat for the

desired heat output.

• Remove the ash pan, making sure to keep it level.

• To keep the cover from sliding off and to keep ash

from falling on the ﬂoor, do not tilt the ash pan for-

ward.

CAUTION: The Encore will be hot while in opera-

tion. Keep children, clothing and furniture away.

Contact may cause skin burns.

If the stove is in operation, close the ash door while

disposing of the ash.

• Properly dispose of the ash in a metal container with

a tight-ﬁtting lid. Store the container outdoors away

from all combustible material.

DO NOT OVERFIRE THIS HEATER. Overﬁring may

cause a house ﬁre, or can result in permanent dam-

age to the stove and to the catalytic combustor. If

any part of the Encore glows, you are overﬁring.

• Return the ash pan to its original position in the

stove, and close and latch the ash door.

• Do not operate the stove with the ash door open.

This will result in over-ﬁring, and could cause dam-

age to the stove, void the warranty, or even lead to a

house ﬁre.

Ash Disposal

You should remove ash before it reaches the top of the

ash pan. Check the level at least once a day. Every few

days, clear any ash from the outer edges of the ﬁrebox.

Most of the ash will fall through the grate. Slice or stir

the ash with a shovel or poker so that it falls through the

grate slots.

Empty the ash pan regularly, typically every one to

three days. The frequency will vary depending on how

you operate your Encore: ash will accumulate faster at

higher heat outputs.

IMPORTANT: Check the level of ash in the ash pan

before reloading the stove. If the ash level is close to

the top edge of the pan, empty the pan according to this

procedure:

Remove ash frequently and place it outdoors in a

metal container with a tight-ﬁtting lid. Place the closed

container of ash on a noncombustible ﬂoor or on the

ground, well away from all combustible materials, pend-

ing ﬁnal disposal. If the ash is disposed of by burial in

soil or otherwise locally dispersed, it should be kept in

the closed container until all cinders have thoroughly

cooled.

• Open the damper.

• Open the griddle or front doors, and use a shovel or

poker to stir excess ash through the ash slots in the

grate down into the ash pan.

You can use wood ash as a garden fertilizer.

• Close the griddle or doors, and unlatch the ash door.

It will pivot, swinging the ash pan out of the stove.

CAUTION: Never use your household or shop vacuum

cleaner to remove ash from the stove; always remove

and dispose of the ash properly.

• Slide the cover onto the pan, making sure it is se-

curely closed. (Fig. 28)

Encore Woodburning Stove

Draft Management

Flue Sizing

A stove is part of a system, which includes the chimney,

the operator, the fuel, and the home. The other parts of

the system will affect how well the stove works. When

there is a good match between all the parts, the system

works well.

The inside size of a chimney for an ‘airtight’ stove

should match the size of the stove’s ﬂue outlet. When

a chimney serves an airtight, more is not better; in fact,

it can be a disadvantage. Hot gases lose heat through

expansion; if we vent a stove with a 152 mm 96”) ﬂue

collar {181 sq cm (28 sq. in.) area} into a 254 x 254 mm

(10” x 10”) ﬂue, the gases expand to over three times

their original size. This cools the gases, which weak-

ens draft strength. If an oversized ﬂue is also outside

the house, the heat it absorbs gets transferred to the

outdoor air and the ﬂue usually stays cool.

Wood stove or insert operation depends on natural

(unforced) draft. Natural draft occurs when the smoke

is hotter (and therefore lighter) than the outdoor air at

the top of the chimney. The bigger the temperature

difference, the stronger the draft. As the smoke rises

from the chimney it provides suction or ‘draw’ that pulls

air into the stove for combustion. A slow, lazy ﬁre with

the stove’s air inlets fully open indicates a weak draft.

A brisk ﬁre, supported only by air entering the stove

through the normal inlets, indicates a good draft. The

stove’s air inlets are passive; they regulate how much

air can enter the stove, but they don’t move air into it.

It’s common for a masonry ﬂue, especially one serving

a ﬁreplace, to be oversized for the stove. It can take

quite a while to warm up such a ﬂue, and the results

can be disappointing. The best solution to an oversized

ﬂue is an insulated steel chimney liner, the same diam-

eter as the stove or insert’s ﬂue outlet; the liner keeps

the smoke warm, and the result is a stronger draft. An

uninsulated liner is a second choice - the liner keeps

the smoke restricted to its original size, but the smoke

still must warm up the air around the liner. This makes

the warm-up process take longer.

Depending on the features of your installation - steel or

masonry chimney, inside or outside the house, matched

to the stove’s outlet or oversized - your system may

warm up quickly, or it may take a while to warm up and

operate well. With an ‘airtight’ stove or insert, one which

restricts the amount of air getting into the ﬁrebox, the

chimney must keep the smoke warm all the way to the

outdoors. Some chimneys do this better than others.

Here’s a list of features and their effects.

Pipe & Chimney Layout

Every turn the smoke must take as it travels to the

chimney top will slow it down. The ideal pipe and chim-

ney layout is straight up from the stove, to a completely

straight chimney. If you’re starting from scratch, use this

layout if possible. If the stovepipe must elbow to enter a

chimney, locate the thimble about midway between the

stove top and the ceiling. This achieves several goals:

it lets the smoke speed up before it must turn, it leaves

some pipe in the room for heat transfer, and it gives you

long-term ﬂexibility for installing a different stove without

relocating the thimble.

Masonry Chimney

Masonry is a traditional material for chimneys, but it

can perform poorly when it serves an ‘airtight’ stove.

Masonry is a very effective ‘heat sink’ - it absorbs a lot

of heat. It can cool the smoke enough to diminish draft.

The bigger the chimney, the longer it takes to warm up.

It’s often very difﬁcult to warm up an outdoor masonry

chimney, especially an oversized one, and keep it warm

enough to maintain an adequate draft.

There should be no more than 2.4 m (8’) of single-wall

stove pipe between the stove and a chimney; longer

runs can cool the smoke enough to cause draft and

creosote problems. Use double-wall stove pipe for long

runs.

Steel Chimney

Most factory-made steel chimneys have a layer of

insulation around the inner ﬂue. This insulation keeps

the smoke warm. The insulation is less dense than ma-

sonry, so a steel chimney warms up more quickly than

a masonry chimney. Steel doesn’t have the good looks

of masonry, but it performs much better.

Single venting

Each ‘airtight’ stove requires its own ﬂue. If an airtight

stove is vented to a ﬂue that also serves an open ﬁre-

place, or a leakier stove, it’s easier for the chimney draft

to pull air in through those channels than it is to pull air

through the airtight, and performance suffers. Imagine

a vacuum cleaner with a hole in the hose to see the ef-

fect here. In some cases the other appliance can even

cause a negative draft through the airtight, and result in

a dangerous draft reversal.

Indoor / Outdoor location

Because the chimney must keep the smoke warm, it’s

best to locate it inside the house. This uses the house

as insulation for the ﬂue and allows some heat release

into the home. An indoor chimney won’t lose its heat

to the outdoors, so it takes less heat from the stove to

heat it up and keep it warm.

Encore Woodburning Stove

smoke rise to the ﬂue more quickly, let more air into the

ﬁrebox, and avoid big loads of ﬁrewood. You should

always see lively, dancing ﬂames in the ﬁrebox; a lazy,

smoky ﬁre is inefﬁcient, can lead to back-pufﬁng, and

can contribute to creosote buildup in the chimney.

Creosote

Creosote is a by-product of slow wood-burning. It’s an

organic tar that can condense in the ﬂue if it’s dense in

the smoke, and slow-moving, and cools off to less than

143° C (290° F). Condensed creosote is volatile, and

can generate chimney ﬁres if it gets hot enough. All the

features that affect chimney draft also affect creosote

condensation - so use whatever combination of installa-

tion features and operational steps will encourage good

draft and minimize creosote production.

Draft Testing

An easy way to test your chimney draft is to close the

stove’s damper, wait a few minutes to let the airﬂow

stabilize, then see whether you can vary the strength

of the ﬁre by swinging the air control open and closed.

Results are not always instant; you may need to wait

a few minutes for a change in the air control setting to

have an effect on the ﬁre. If there’s no change, then the

draft isn’t strong enough yet to let you close the damper,

and you’ll need to open it for a while longer and manage

the ﬁre with the air inlet until the draft strengthens. If you

keep track of your burning habits and relate them to their

effects on the stove’s operation, you’ll be rewarded with

good performance and a safe system.

Because letting the smoke cool off and slow down is

one of the keys to creosote production, it makes sense

to line a chimney to match the stove’s outlet size, for

safety reasons as well as performance. Consult a quali-

ﬁed installer and check local and national codes for

recommended chimney size.

Fuel

Even the best stove installation will not perform well

with poor fuel. The best fuel is hardwood that has air-

dried 12-18 months. Softwood burns, but not as long as

hardwood. Fairly ‘green’ wood has a good amount of

moisture in it; it will burn, but some of the heat potential

is used to drive the remaining moisture off the wood.

This reduces the amount that reaches your home and

can contribute to a creosote problem. There are mois-

ture meters available for ﬁrewood; you can also judge

your wood by its appearance and weight. If you get it

green, lift a piece and get a sense of its weight; it can

lose a third or more of its weight as it dries. Also look at

the ends of a log; as it dries it shrinks and often cracks.

The more weathered and cracked a piece is, the drier

it is.

In many cases, local or national codes require the

installation of permanently open air vents, particularly

with larger appliances (i.e. above 5 kW). Refer to these

codes to determine speciﬁc requirements for your

installation.

Negative Pressure

Good draft also depends on a supply of air to the stove;

a chimney can’t pull in more air than is available to it.

Sluggish draft results when a house is tight enough to

prevent the ready ﬂow of air to the stove, or by competi-

tion between the stove and other equipment that sends

indoor air outside - especially power-driven equipment

like range hoods, clothes dryers, etc. If the chimney

draws well with all other equipment turned off (or

sealed, in the case of ﬁreplaces and/or other stoves),

then you simply need to be careful with timing the use

of the other gear. If you need to crack a nearby window

or door to enable the chimney to pull well, that’s a sign

that you should install an outside-air intake to bring

combustion air directly to the stove. For most of our

stoves we carry adapters to attach to the stove to con-

nect an air duct for outdoor combustion air.

Dry wood burns readily with a good chimney draft. But

with modern stoves, especially catalytic ones, the wood

can be too dry. While extra-dry wood has little creosote

in it, the remainder can ‘gas out’ from the wood quickly

and densely enough to overload the catalytic burner.

If you hear a rumbling or roaring noise, like a propane

torch, from the stove, that is a sign the catalyst is seri-

ously overﬁring. The catalyst is a platinum ﬁlm on a

ceramic base; the metal can get to higher temperatures

than the ceramic can take, and overﬁring the catalyst

can break it. Dry wood can also burn out faster than

you want. If your dry wood burns out too quickly or

overloads the catalyst you can mix in greener wood to

slow the ﬁre down.

Conclusion

Wood-burning is an art rather than a science. Once the

stove and chimney system are in place, you can only

vary your technique, mostly your timing, to achieve

good results. If you keep track of your burning habits

and relate them to their effects on the stove’s operation,

you’ll be rewarded with good performance and a safe

system.

Back-pufﬁng

Back-pufﬁng results when the ﬁre produces volatile

gases faster than the chimney draft pulls them out of

the ﬁrebox. The gases back up in the ﬁrebox till they’re

dense enough and hot enough to ignite. If your stove

back-puffs, you should open the damper to let the

dealer.

1. Remove the right and left door assemblies by raising

the door until the lower hinge pin clears its drilling;

then, angle the door bottom slightly outward and

pull down to release the upper hinge pin. Place the

doors face down on a padded work surface.

Keep Your Stove Looking New

and Working Its Best

Let the ﬁre in the stove go out and allow the stove to

cool completely before beginning any maintenance

procedure.

2. Remove the screws that hold the retainer clips in

place, and remove the clips. On the right door, re-

move the Phillips head machine screw that secures

the door manifold to the upper right of the door (as it

faces you). Swing the door manifold out of your way

and remove the clip beneath it as well.

Care of the Cast Iron Surface

An occasional dusting with a dry rag will keep the painted

cast iron of your Encore looking new.

The stove’s paint can be touched up as needed. First,

mask the areas, such as enamelled parts, glass, or

handles, around the spot to be painted. Clean the spot

with a wire brush. Remove the griddle and set it aside.

3. Carefully lift the broken glass panel from the door.

Then, touch up the stove with Vermont Castings’ high

temperature stove paint. Apply the paint sparingly; two

light coats of paint are better than a single heavy one.

Care of the Porcelain Enamel Surface

Use a dry or slightly damp rag or soft brush to remove

spills or stains. For difﬁcult jobs that require a cleaning

agent, use only a kitchen appliance cleaner or polish

recommended for use on enamel surfaces.

Cleaning the Glass

Most of the carbon deposits on the glass will burn off

during hot ﬁres.

Retainer Clips (4)

ST640

However, the ash residue that accumulates on the

glass surface should be removed regularly to prevent

etching. To clean the glass, follow this procedure:

Installing the Glass

• Be sure the glass is completely cool.

• Clean the glass with water or a cleaner made espe-

cially for this purpose. Do not use abrasive cleaners.

Check the gasket around the window; it should be soft

and resilient so the glass will seal properly against the

door. Replace the gasket if it has hardened or if it is

compressed.

• Rinse the glass thoroughly.

• Dry the glass completely.

1. Center the ﬁrst pane of glass on the gasket. Be sure

to place the glass so the infrared reﬂective coating is

on the exterior side.

Replace Broken Glass Immediately

Do not operate your stove if the glass in the doors is

damaged.

2. Secure the glass on both doors with the retainer

clips except the one that belongs under the manifold

of the right door, but leave the screws a little loose.

If you need to replace the glass, use only the high tem-

perature ceramic glass supplied by Vermont Castings.

Do not use substitutes. Be sure to specify left or right

glass; the panels are not interchangeable.

Position the remaining clip under the right door

manifold, and swing the manifold back into position

on the door. Make sure the screw passing through

the end of the manifold nearest the center of the

door also passes through the retainer clip.

2. Turn the pressure screw approximately one half turn

clockwise.

3. Tighten the lock nut. Keep the pressure screw from

turning as you tighten the nut. Re-test the damper.

3. Replace the doors on the stove. Remove the griddle

so you can reach in through the opening to posi-

tion the manifold. Move the door manifold as high

as possible without actually touching the upper air

manifold, and as far toward the center of the stove

as possible without hitting the door manifold on the

other door. Tighten all screws.

4. Open and close the doors to check that the door

manifold does not interfere with either of the other

manifolds. Adjust as necessary.

Check the Operation

of the Primary Air Shutter

The primary air shutter is located at the back of the ash

drop and is visible from the back of the stove. (Fig. 31)

The shutter must open and close freely when you move

the thermostat lever. If it does not, remove any obstruc-

tion. If you need assistance, consult your local Vermont

Castings Authorized Dealer.

ST642

Fig. 32 Adjusting the damper.

Tighten the Damper Handle as Needed

A handle on the left side of the stove controls the

damper. The handle attaches to the damper rod with a

set screw. Periodically check the set screw and tighten

as necessary.

How to Adjust the Door Latches

The Encore’s front doors, as well as its ash pan door,

should close securely to prevent accidental open-

ing and to keep air from leaking into the stove. On

adequately adjusted doors, the handles should resist

slightly as they are turned to the closed position and the

doors themselves should be drawn slightly toward the

stove.

Over time, the gasket around the doors will compress

and the latch may need adjustment.

Primary Air

Shutter

To adjust the handle on the front doors, open the

door on which the handle is mounted and rotate the

handle one full turn counterclockwise. Since this handle

is threaded into the front door, a complete revolution will

adjust it enough so the doors close securely.

ST641

Fig. 31 The primary air shutter must move freely.

Do not change the adjustment of the cable in an at-

tempt to gain increased ﬁring. The air shutter controls

how much air can enter the stove, but chimney draft

is the force that pulls air into the stove. If changing the

thermostat handle position does not lead to changes in

the ﬁre’s intensity, it is probably due to weak chimney

draft (in the case of a weak ﬁre you can’t increase) or

an air leak in the stove (in the case of a ﬁre you can’t

decrease).

To adjust the latch on the ash pan door, loosen the

small lock nut, rotate the striker screw a half-turn, and

re-tighten the small lock. Hold the striker screw to keep

it from turning as you tighten the lock nut. Make repeat-

ed small adjustments until the setting is right.

Adjust the Damper as Needed

The tension on the Encore’s damper is adjustable to

compensate for compression of the gasket that seals

the damper to the upper ﬁreback. To adjust the damper:

1. Remove the griddle. Loosen the lock nut at the cen-

ter of the damper.

• Then, open the stove damper and once again

check the smoke leaving the chimney. Signiﬁcantly

more smoke should be seen when the stove damper is

open and exhaust does not pass through the combus-

tor. Be careful not to confuse smoke with steam from

wet wood, however. Steam dissipates in the air quickly;

smoke does not.

If this test indicates a problem, consider other possible

factors as well, such as the time of year or a change in

the quality of your fuel. In spring and fall, draft is weaker

than it is in colder winter weather, and ﬁres can burn

sluggishly. Small, hot ﬁres are a good solution under

these conditions.

Fig. 33 Turn the door latch striker screw in or out to tighten or

The Catalytic Element

Also, consider any changes in your operating routine.

Inspection and Cleaning

Once you have ruled out any other possible causes for

a decline in performance, you may inspect the combus-

tor.

This wood heater contains a catalytic combustor, which

needs periodic inspection and replacement for proper

operation. In the United States it is against the law to

operate this wood heater in a manner inconsistent with

the operating instructions in this manual, or if the cata-

lytic element is deactivated or removed.

Inspecting the Combustor

1. Release the hood from the ﬁreback by swinging the

hood upward and then sliding it to either side. (Fig.

34)

2. Using a ﬂashlight, and a mirror if necessary, exam-

ine the combustor. If no ﬂy ash or damage is visible,

the inspection is complete and you may replace the

hood. If further examination or cleaning is necessary,

go to Step 3.

Under normal operating conditions, the catalytic com-

bustor should remain active for two to six years (de-

pending on the amount of wood burned). However, it

is important to monitor the combustor periodically to

ensure that it is functioning properly, as well as to deter-

mine when it needs to be replaced. A non-functioning

combustor will result in a loss of heating efﬁciency, and

an increase in creosote and emissions.

Hood

Inspect the combustor “in place” for ﬂy ash accumula-

tion and physical damage three times per year. Do not

remove the combustor unless a more detailed inspec-

tion is warranted because of diminished performance

as outlined below.

The refractory package that houses the catalytic com-

bustor should be inspected annually for a buildup of ﬂy

ash and cleaned if necessary. This may be done when

you examine the combustor.

Fireback

ST643

When to Suspect a Combustor Problem

Fig. 34 Release the hood by lifting its bottom edge and slid-

ing to one side.

The best way to evaluate the performance of your

Encore’s combustor is to observe the amount of smoke

leaving the chimney — both when the combustor has

achieved “light-off” and when it has not. Follow these

steps:

3. Release the ﬁreback by prying the left and right

wedges upward. (Fig. 35)

4. Swing the ﬁreback forward and up to remove it from

the stove. (Fig. 36)

5. Remove the catalytic combustor’s refractory access

cover, then remove the combustor.

• With a ﬁre going and the combustor properly ac-

tivated, with the damper closed to route smoke through

it as described in the Operation Section, go outside and

observe the smoke leaving the chimney.

Operate the stove in your typical manner for two weeks,

inspecting the chimney and the chimney connector

frequently during this period.

Fireback

If creosote is not building up as fast, it is likely the

performance change was caused by ﬂy ash deposits

on the catalytic element. However, continue the inspec-

tions of the chimney system for a few weeks to ensure

proper performance continues.

If you continue to ﬁnd a signiﬁcant creosote buildup or if

you continue to see excessive smoke from the chimney,

the catalytic element will need to be replaced. Contact

your nearest Vermont Castings’ Authorized Dealer for

information about a replacement element.

Vermont Castings dealer.

6. Check the combustor’s honeycomb-like element

for a buildup of ﬂy ash. If any is evident, take the

combustor outside and clean it by blowing air gently

through it.

7. Inspect the element for damage or degradation.

Although small hairline cracks will not affect per-

formance, the element should be essentially intact.

If the element is broken in pieces or has sections

missing, it should be replaced. Call your local Ver-

mont Castings’ Authorized Dealer for a replacement

element.

Replace the Stove Gaskets as Needed

Your Encore uses rope-type ﬁberglass gaskets to make

a tight seal between some parts. With use, particularly

on those parts that move, gaskets can become brittle

and compressed and can begin to lose their effective-

ness. These will need periodic replacement.

All of the gaskets are made of ﬁberglass. The sizes of

replaceable gasket are listed below, along with their

applications.

While the catalytic element is removed, check the

condition of the secondary air probe. Use an inspec-

tion mirror to locate the probe within the combustion

chamber. The probe should extend 25-38 mm (1” to

1¹⁄₂”) into the chamber and show no signs of deteriora-

tion, such as warping, corrosion, or short length. (Fig.

37) A damaged secondary air probe can affect catalytic

performance. If the probe needs replacement, contact

your local dealer.

meets before trimming any excess. Do not overlap the

gasket ends or leave ends with ragged edges.

7. Press the gasketed part ﬁrmly against its normal

mating surface to seat the gasket evenly in its channel.

Close and latch the door to do this, or tap other parts

with the rubber mallet (or hammer/block of wood).

Wait until the ﬁre is out and the stove has cooled. Be

sure to follow the standard safety procedure for working

with dusty materials: Wear safety goggles and a dust

mask.

8. Clean any excess cement from around the chan-

nel, then let the cement that holds the new gasket dry

thoroughly.

The procedure for replacing gaskets is the same re-

gardless of the gasket location. Follow these steps:

1. Remove the existing gasket by grasping an end and

pulling ﬁrmly.

Adjust the Door If Necessary

The stove’s door(s) may need adjustment after you

have regasketed it. Initially, it may require loosening to

accommodate the new gasket; after a few weeks, it

may need tightening to compensate for compression of

the new gasket. The directions for adjusting the doors

are on Page 22.

2. Use a wire brush or the tip of a screwdriver to clean

the channel of any remaining cement or bits of gasket.

(Fig. 38) Remove stubborn deposits of cement with a

cold chisel if necessary.

Permanent Encore Gaskets

Other gaskets form seals between non-moving parts,

but these are not subject to the same wear and dete-

rioration as gaskets on moving parts. It is unlikely that

you will ever need to replace these gaskets unless the

involved parts are disassembled and then put back

together. If this is the case, the job should be done only

by a qualiﬁed service technician.

4. Remove the gasket from the channel, place it on a

wood cutting surface, and cut it at the marked spot with

a utility knife. Twist the ends slightly to keep the gasket

Creosote

Your Encore is designed to reduce creosote build-up

signiﬁcantly. However, regular chimney inspection and

maintenance must still be performed. For safety, good

stove performance, and to protect your chimney and

chimney connector, inspect your chimney and chimney

connector on a regular schedule. Clean the system if

necessary. Failure to keep the chimney and connector

system clean can result in a serious chimney ﬁre.

ve Gasket

Sto

When wood is burned slowly, it produces tar, organic

vapors and moisture that combine to form creosote.

The creosote vapors condense in the relatively cool

chimney ﬂue of a slow-burning ﬁre. As a result, creo-

sote residue accumulates on the ﬂue lining. When ignit-

ed, this creosote makes an extremely hot ﬁre within the

ﬂue system that can damage the chimney and overheat

adjacent combustible material. If a signiﬁcant layer of

creosote has accumulated —3 mm (1/8”) or more — it

should be removed to reduce the risk of a chimney ﬁre.

If you do experience a chimney ﬁre, act promptly

to:

Annual Maintenance

Every Spring, at the end of the heating season, perform

a thorough cleaning, inspection and repair. The stove

and chimney system should be inspected and main-

tained by a qualiﬁed engineer and include the following:

• Close the damper and thermostat lever.

• Get everyone out of the house.

• Call the Fire Department.

You should inspect the system every two weeks during

the heating season as part of a regular maintenance

schedule. To inspect the chimney, let the stove cool

completely. Then, using a strong light, sight up through

the ﬂue collar into the chimney ﬂue. If it is not possible

to inspect the ﬂue system in this fashion, the stove must

be disconnected to provide better viewing access.

• Thoroughly clean the chimney and chimney connec-

tor.

• Inspect the chimney for damage and deterioration.

Replace weak sections of prefabricated chimney.

Have a mason make repairs to a masonry chimney.

• Inspect the chimney connector and replace any

damaged sections.

Clean the chimney using a brush the same size and

shape as the ﬂue liner. Flexible ﬁberglass rods are used

to run the brush up and down the liner, causing any

deposits to fall to the bottom of the chimney where they

can be removed through the clean-out door.

• Check gasketing for wear or compression, and re-

place if necessary.

• Inspect and clean the catalytic element, and vacuum

out the ash at the bottom of the back plate after re-

moving the lower ﬁreback. Lightly clean the refracto-

ry assembly that houses the element but be careful

not to damage the refractory material, which is very

fragile.

Clean the chimney connector by disconnecting the sec-

tions, taking them outside, and removing any deposits

with a stiff wire brush. Reinstall the connector sections

after cleaning, being sure to secure the joints between

individual sections with sheet metal screws.

• Check door and damper handles for tightness. Ad-

just if needed.

If you cannot inspect or clean the chimney yourself,

contact your local Vermont Castings’ Dealer or a profes-

sional chimney sweep.

• Check heat shield screws. Tighten as necessary.

• Clean dust from the inner sides of bottom, rear and

connector heat shields.

• Remove ashes from the ash pan and replace with

moisture absorbing material (such as cat litter) to

keep the stove interior dry.

• Touch up the paint on black stoves.

Encore Woodburning Stove

Appendix: Catalytic Combustor

In any chemical reaction, including the combustion

Masking and Poisoning

process, there are certain conditions which must be

met before the reaction can take place. For example, a

reaction may require a certain temperature, or a certain

concentration of the reactants (the combustion gases

and oxygen), or a certain amount of time. Catalysts,

though not changed themselves during the reaction,

have the ability to act at a molecular level to change

these requirements. In the Encore’s secondary com-

bustion chamber the catalyst reduces the temperature

at which secondary combustion can start from the 540-

650° C (1000 - 1200° F) range to the 260-315° C (500

- 600° F) range, increasing efﬁciency, and reducing

creosote and emissions.

While the catalyst itself does not enter into the combus-

tion process, certain elements, such as lead and sulfur,

can attach to the active sites on the surface of the hon-

eycomb. Though the catalyst is still there, it is covered,

or masked, by the contaminant, and cannot function. To

avoid this situation, it is important not to burn anything

in your Encore that is a source of these contaminants.

Particularly avoid painted or treated wood, coal, house-

hold trash, colored papers, metal foils, or plastics.

Chemical chimney cleaners may also contain harmful

elements. The safest approach is to burn only untreat-

ed, natural wood.

The catalytic reaction does have some limitations of its

own. Primary among these is that the reactants (the

gases) come into close physical contact with the cata-

lyst itself.

Flame Impingement

The catalytic element is not designed for exposure to

direct ﬂame. If you continually overﬁre your Encore, the

chemistry of the catalyst coating may be altered, inhibit-

ing the combustion process.

To ensure the necessary contact, the catalytic element

in your Encore is composed of a ceramic base in the

shape of a honeycomb. Each of the honeycomb’s many

surfaces carries a coating of the catalyst (usually a

noble metal such as platinum or palladium). The large

surface area exposed in this form ensures that the com-

bustion gases have the greatest opportunity to come in

contact with the catalyst.

Thermal degradation of the ceramic base may also oc-

cur, causing the element to disintegrate. Stay within the

recommended guidelines of the Operation section.

Mechanical Damage

If the element is mishandled, damage may occur.

Always treat the element carefully. Remember the cata-

lyst is made of a ceramic material; treat it as you would

ﬁne china. Hairline cracks will not affect the perfor-

mance of the catalyst, as long as the steel sleeve holds

the element in the proper position.

Loss of catalytic activity will be apparent in several

ways. First you may notice an increase in fuel con-

sumption. Second, there will be a visible increase in the

rate at which creosote builds up in your chimney con-

nector system. You may also notice a heavy discharge

of smoke from the chimney. There are a number of

catalytic problems which can cause loss of activity:

Peeling

The surface coat may peel if the catalytic element is

frequently subjected to excessive temperatures. Follow

the operating instructions carefully to avoid this type of

damage.

Blockage

While the honeycomb pattern ensures good contact, it

also increases the resistance to ﬂow of the combustion

gases, and, because of the many surfaces, provides

more places for creosote and ﬂy ash to deposit. It is

important to follow the operating instructions in order

to minimize these deposits, and to periodically inspect

your catalyst for signs of blockage.

General

Every Vermont Castings’ Encore is equipped with either

a Corning “Long-Life”^®or a Technical Glass Products

“Honeycomb”^®combustor. The products are equivalent.

If you must ship your catalytic element for any reason,

remember its fragile nature. Place the element in a

plastic bag, and package it with a generous amount of

shock absorbing material.

Encore Woodburning Stove

Warranty

Limited 3 Year Warranty

CFM Corporation warrants that this woodburning stove will be free

of defects in material and workmanship for a period of three years

from the date you receive it, except that the catalyst, thermostat

assembly, handles, glass door panels, cement, and gasketing shall

be warranted as described below.

CFM Corporation will repair or replace, at its option, any part found

to be defective upon inspection by a Vermont Castings, Authorized

Dealer. The customer must return the defective part or the stove, with

shipping prepaid, to the Authorized Dealer or pay for any Authorized

Dealer in-home travel fees or service charges for in-home repair work.

It is the dealer’s option whether the repair work will be done in the cus-

tomer’s home or in the dealer’s shop. If, upon inspection, the damage

is found to be the fault of the manufacturer, repairs will be authorized at

no charge to the customer for parts and/or labor.

Exclusions & Limitations

1. This warranty is transferable; however, proof of original retail pur-

chase is required.

2. This warranty does not cover misuse of the stove. Misuse includes

overﬁring which will result if the stove is used in such a manner as

to cause one or more of the plates to glow red. Overﬁring can be

identiﬁed later by warped plates and areas where the paint pigment

has burned off. Overﬁring in enamel ﬁreplaces is identiﬁed by bub-

bling, cracking, chipping and discoloration of the porcelain enamel

ﬁnish. CFM Corporation offers no warranty on chipping of enamel

surfaces. Inspect your woodburning stove prior to accepting it for

any damage to the enamel.

3. This warranty does not cover misuse of the stove as described

in the Owner’s Guide, nor does it cover an stove which has been

modiﬁed unless authorized by a CFM Corporation representative in

writing. This warranty does not cover damage to the stove caused

by burning salt saturated wood, chemically treated wood, or any fuel

not recommended in the Owner’s Guide.

Any woodburning stove or part thereof that is repaired or replaced

during the limited warranty period will be warranted under the terms of

the limited warranty for a period not to exceed the remaining term of the

original limited warranty or six (6) months, whichever is longer.

4. This warranty does not cover a stove repaired by someone other

than a Vermont Castings Authorized Dealer.

Limited 1 Year Warranty

5. Damage to the unit while in transit is not covered by this warranty

but is subject to a claim against the common carrier. Contact

Vermont Castings Authorized Dealer from whom you purchased

your stove or CFM Corporation if the purchase was direct. (Do not

operate the stove as this may negate the ability to process the claim

with the carrier.)

The following parts of the woodburning stove are warranted to be free

of defects in material and workmanship for a period of one year from

the date you receive it: The thermostat assembly, handles, glass door

panels, cement, and gasketing. Any of these items found to be defec-

tive will be repaired or replaced at no charge, upon the return of the

part with postage prepaid to a Vermont Castings Authorized Dealer.

6. Claims are not valid where the installation does not conform to local

building and ﬁre codes or, in their absence, to the recommendations

in our Owner’s Guide.

Any part repaired or replaced during the limited warranty period will

be warranted under the terms of the limited warranty for a period not

to exceed the remaining term of the original limited warranty or six (6)

months, whichever is longer.

7. The salt air environment of coastal areas, or a high-humidity en-

vironment, can be corrosive to the porcelain enamel ﬁnish. These

conditions can cause rusting of the cast iron beneath the porcelain

enamel ﬁnish, which will cause the porcelain enamel ﬁnish to ﬂake

off. This warranty does not cover damage caused by a salt air or

high-humidity environment.

Limited Catalyst Warranty

The catalyst will be warranted for a six year period as follows: If the

original catalyst or a replacement catalyst proves defective or ceases to

maintain 70% of its particulate emission reduction activity (as measured

by an approved testing procedure) within 24 months from the date the

stove is received, the catalyst itself will be replaced free.

8. CFM Corporation shall have no obligation to enhance or update any

unit once manufactured.

IN NO EVENT SHALL CFM CORPORATION BE LIABLE FOR INCI-

DENTAL AND CONSEQUENTIAL DAMAGES. ALL IMPLIED WAR-

RANTIES, INCLUDING THE IMPLIED WARRANTIES OF MERCHANT-

ABILITY AND FITNESS, ARE LIMITED TO THE DURATION OF

THIS WRITTEN WARRANTY. THIS WARRANTY SUPERCEDES ALL

OTHER ORAL OR WRITTEN WARRANTIES.

From 25 - 72 months a pro-rated credit will be allowed against a re-

placement catalyst and the cost of labor necessary for its installation at

the time of replacement.

For stove purchases made after June 30, 1990, a third year

(25 - 36 months) of no charge replacement will be made when combus-

tor failure is due to thermal degradation of the substrate (crumbling of

ceramic material). The customer must pay for any in-home travel fees,

service charges, or transportation costs for returning the stove to the

Authorized Dealer.

Some states do not allow the exclusion or limitations of incidential and

consequential damages or limitations on how long an implied warranty

lasts, so the above limitations may not apply to you. This warranty gives

you speciﬁc rights and you may have other rights which vary from state

to state.

If a defect is noted within the warranty period, the customer should

contact a Vermont Castings Authorized Dealer or CFM Corporation if

the purchase was direct with the following information:

1. Name, address, and telephone number of the purchaser.

2. Date of purchase.

Any replacement catalyst will be warranted under the terms of the

catalyst warranty for the remaining term of the original warranty. The

purchaser must provide the following information in order to receive a

replacement catalyst under the terms of this limited warranty:

1. Name, address and telephone number.

3. Serial number from the label on the back.

4. Nature of the defect or damage.

5. Any relevant information or circumstances, e.g., installation,

mode of operation when defect was noted.

2. Proof of original purchase date.

3. Date of failure of catalyst.

4. Any relevant information or circumstances regarding determina-

tion of failure.

A warranty claim will then start in process. CFM Corporation reserves

the right to withhold ﬁnal approval of a warranty claim pending a visual

inspection of the defect by authorized representatives.

5. In addition, the owner must return the failed catalyst.
