Encore 1450 Non-Catalytic Woodburning Stove

Installation

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.

Outside Air

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

tested clearance requirements.

• The ﬂoor protector is large enough and is con-

structed properly to meet all tested requirements.

Another solution is to install a permanent outside air

supply to the stove and/or room. In fact, bringing air for

combustion from outside the home directly to the air in-

let of the stove is required for new construction in some

areas. The Encore NC is equipped with an outside con-

nection as standard equipment.

• You have all necessary permits from local author-

ities.

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 and meets current UL and ULC safety

standards, and gives the name of the testing laboratory.

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 NC, refer to Figure 2 for

suggested chimney heights at various altitudes. Chim-

ney height should be measured from the ﬂue collar to

the top of the chimney. The recommended minimum

chimney height is 16’ (4.9 m).

However, codes vary in different areas. Before starting

the installation, review your plans with the local building

authority. Your local dealer can provide any additional

information needed.

For any unresolved installation issues, refer to the

National Fire Protection Association’s publication ANSI/

NFPA 211 Standard for Chimneys, Fireplaces, Vents

and Solid Fuel Burning Appliances. For Canada, the

equivalent publication is CSA CAN-B365 Installation

Code for Solid Fuel Burning Appliances and Equipment.

These standards are the basis for many national codes.

They are nationally recognized and are accepted by

most local authorities. Your local dealer or your local

building ofﬁcial may have a copy of these regulations.

Encore 1450 Non-Catalytic Woodburning Stove

Masonry Chimneys

What Kind of Chimney to Use

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.

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 that complies with the requirements

for Type HT chimneys in the Standard for Chimneys,

Factory-Built, Residential Type and Building Heating

Appliance, UL 103. (Fig. 3) The chimney and chimney

connector must be in good condition and kept clean.

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.

A prefabricated double-

wall insulated chimney

The chimney should be thoroughly cleaned before use.

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.

A prefabricated metal chimney must be one tested and

listed for use with solid-fuel burning appliances to the

High-Temperature (H.T.) Chimney Standard UL-103-

1985 (2100°F) for the United States, and High Temper-

ature (650°C) Standard ULC S-629 for Canada.

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.

DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE

SERVING ANOTHER APPLIANCE.

The chimney should extend at least 3’ (914 mm) above

the highest point where it passes through a roof, and at

least 2’ (610 mm) higher than any portion of a building

within 10’ (3 m). (Fig. 4)

Chimney Size

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

for venting into a masonry chimney with a nominal

ﬂue size of 8” x 8” (203 x 203 mm) or 8” x 12” (203 x

305mm), and into a round ﬂue with nominal ﬂue size of

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

is approved for venting into a masonry chimney with a

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

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

For proper draft and good performance, any chimney

used with an Encore should extend at least 16’ (5 m)

above the ﬂue collar of the stove.

Whatever the ﬂue collar size, an Encore may be vented

into larger chimneys as well. However, chimneys

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

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.

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.

Consult your local dealer about these special pieces.

Double-wall Chimney Connectors

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.

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 the

stove’s exhaust gases, and may release toxic fumes

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

8 “ (203mm) in diameter.

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.

NOTE: For installations us-

ing double-wall connectors,

minimum clearances must

conform to the listed clear-

ances in the clearance chart

on Page 15.

Fig. 5 the crimped end

of the connector points

toward stove.

In horizontal runs of chimney connector, maintain a dis-

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

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

Slope horizontal runs of connector upward 1/4” per foot

(6mm per meter) going from the stove toward the chim-

ney. The recommended maximum length of a horizontal

run is 3’ (1m), and the total length should be no longer

than 8’ (2.4m). In cathedral ceiling installations, extend

the prefabricated chimney downward to within 8’ (2.4)

of the stove.

If the Encore is equipped with

the 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 connec-

tor.

Securing the Single-wall Connector to a

Prefabricated Chimney

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.

Wear gloves and protective eyewear when drilling,

cutting or joining sections of chimney connector.

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. 5)Using the holes in the ﬂue collar as guides,

drill 1/8” (3mm) 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.

Special adapters are available from your local dealer

which connect the prefabricated chimney to the chim-

ney connector. The top of such adapters attach directly

to the chimney or to the chimney’s ceiling support pack-

age, while the bottom of the adapter is screwed to the

chimney connector.

• 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 connector serve

as guides when you drill 1/8” (3mm) holes in the bot-

tom of the next section.

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.

• Secure the chimney connector to the chimney. In-

structions for various installations follow.

• Be sure the stove and chimney connector are in-

stalled at the correct distances from nearby com-

bustible materials as per tested clearance. Refer to

Encore Clearance Diagrams.

Securing the Single-wall Connector to a

Masonry Chimney

Fireplace Installations

Both freestanding masonry chimneys and ﬁreplace ma-

sonry 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 recommen-

dations in the Wall Pass-Through section later in this

manual.

Above the Fireplace

The Encore may be connected to a chimney above

a ﬁreplace opening. (Fig. 8) 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 are 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 24” (610mm). To ﬁnd out

how much this clearance may be reduced with heat

shields, refer to the clearance chart on Page 15.

Fig. 9 In this installation, the chimney connector enters the

In the United States, the National Fire Protection As-

sociation (NFPA) has established guidelines for passing

chimney connectors through combustible walls. Many

building code inspectors follow these guidelines when

approving installations.

ST244

Fig. 8 In this installation, the chimney connector is attached

to the chimney above the ﬁreplace opening.

Figure 10 shows one NFPA-recommended method.

All combustible material in the wall is cut away from

the single-wall connector to provide the required 12”

(305mm) clearance. Any material used to close up the

opening must be noncombustible.

Through the Fireplace

If your ﬁreplace opening height is at least 26¹⁄₂"

(675mm), you may install an Encore through the open-

ing 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. 9)

Three other methods are also approved by the NFPA:

• Using a section of double-wall chimney with a 9”

(229mm) clearance to combustibles.

Fireplace installations, whether connected to the ﬂue

above or through the ﬁreplace opening, have special

clearance requirements to adjacent trim and the mantel.

You’ll ﬁnd the required safe clearances for Encore ﬁre-

place installations on Page 12 and Figure 16.

• Placing a section of chimney connector inside a

ventilated thimble, which in turn is separated from com-

bustibles by 6” (152mm) of ﬁberglass insulating mate-

rial.

• Placing a section of chimney connector inside a

section of 9” (230mm) diameter, solid-insulated, factory-

built chimney, with 2” (50mm) of air space between the

chimney section and combustibles.

Floor protection requirements also apply to ﬁreplace

installations. This information is on Page 10.

Wall Pass-Throughs

In Canada, The Canadian Standards Association has

established different guidelines. Figure 10 shows one

method, in which all combustible material in the wall is

cut away to provide the required 18” (457mm) clear-

ance for the connector. The resulting space must re-

main 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

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

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 1450 Non-Catalytic Woodburning Stove

Wall Stud

Floor Protection

A tremendous amount of heat radiates from the bottom

plate of your stove. The ﬂoor area directly under and

around the stove will require protection from radiant

heat as well as from stray sparks or embers that may

escape the ﬁrebox.

Chimney

Connector

Heat protection is provided through the bottom heat

shield. Spark, ember and thermal protection must be

provided by a ﬂoor protector constructed with noncom-

bustible material as speciﬁed.

12” Noncombustible

Material

Most installations will require the bottom heat shield be

attached. Only when the stove is placed on a complete-

ly noncombustible surface such as unpainted concrete

over earth may it be used without the heat shield.

Floor Pro-

tection

ST493

Even when the bottom heat shield is installed, you

must provide special protection to the ﬂoor beneath.

For installation with the heat shield attached, use an

approved 1/2” (13 mm) noncombustible hearth pad with

k = 0.84 BTU/in ft²hr °F or an equivalent material with

an R-value of at least 0.59. (Refer to “How to Determine

if Alternate Floor Protection Materials are Acceptable”

section) The ﬂoor protector may be covered with a

decorative noncombustible material if desired. Do not

obstruct the space under the heater.

Fig. 10 An approved wall pass-through for the United States.

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. In Canada, this type of installation must conform

to CAN/CSA-B365, Installation Code for Solid Fuel

Burning Appliances and Equipment.

NOTE: Do not vent your Encore into a factory-built

(zero-clearance) ﬁreplace. These appliances together

with their speciﬁc chimneys are designed as a sys-

tem for use as ﬁreplaces. It may void the listing or be

hazardous to adapt factory-built ﬁreplaces for any other

use.

Protection requirements vary somewhat between the

Untied States and Canada as follows:

U. S. installations the ﬂoor protector is required under

the stove and must extend at least 16” (not including

the ash lip) from the front of the stove (“F”, Fig. 12), and

at least 6” from the sides and rear. (“D” and “E”, Fig.

12) It must also extend under the chimney connector

and 2” to either side. (“C”, Fig. 12) For the 8” (203 mm)

connector, the protector must be a minimum of 12”

(305 mm) wide. For the 6” (152 mm) connector, the

protector must be 10” (254 mm) wide. The protector

must be centered under the connector.

18” (460mm) clear

space all around

the pipe

To meet these requirements, a ﬂoor protector must be

at least 39” wide and 45” deep.

In Canada: A noncombustible ﬂoor protector is required

under the stove as well. The ﬂoor protector must

extend 18” (450 mm) to the front (“F”, Fig. 12), and 8”

(200 mm) from the sides and rear. (“D” and “E”, Fig. 12)

ST494

To meet these requirements, a ﬂoor protector must be

at least 43” (1092 mm) wide and 49” (1245 mm) deep.

Fig. 11 An approved wall pass-through for Canada.

Floor protection also must extend under the chimney

connector and 2” (51 mm) to either side. (“C”, Fig. 12)

For the 8” (203 mm) connector, the protector must be

a minimum of 12” (305 mm) wide. For the 6” (152 mm)

connector, it must be at least 10” (254 mm) wide. The

protector must be centered under the connector.

DO NOT CONNECT AN ENCORE TO ANY AIR DIS-

TRIBUTION DUCT OR SYSTEM.

How to Determine if Alternate Floor

Protection Materials are Acceptable

Floor Protection for Fireplace Installations

Do not assume that your ﬁreplace hearth is completely

noncombustible.

All ﬂoor protection must be noncombustible (i.e. met-

als, brick, stone, mineral ﬁber boards, etc.). Any organic

materials (i.e. plastics, wood paper products, etc.) are

combustible and must not be used. The ﬂoor protection

speciﬁed includes some form of thermal designation

such as R-value (thermal resistance) or k-factor (ther-

mal conductivity).

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. 13) 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.

Procedure:

Encore 1450 Non-Catalytic Woodburning Stove

The Encore 1450 includes a bottom heat shield that is

needed in most installations. Refer to Page 9 for more

information on required ﬂoor protection. In addition, top

exit installations that do not include wall protection must

include a vertical ﬂue collar heat shield. (Consult clear-

ance chart on Page 15.) The vertical ﬂue collar heat

shield is sold as a separate accessory.

Keep the Stove a Safe Distance

from Surrounding Materials

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.

In general, the greatest clearance is required when you

place a stove and its connector without accessory heat

shields near walls without heat shields.

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 UL and ULC standards. These clearance require-

ments must be strictly observed.

For example, when the Encore is installed parallel to

the rear wall and no shields are used, the rear edge

of the top must be at least 29” (737 mm) from the wall

behind it and at least 17” (432 mm) from walls on either

side.

If the Encore is installed in a corner and no shields

are used, the corners of the stove must be at least 28”

(711 mm) from nearby walls.

In addition, furnishings and other combustible materi-

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

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

the stove and moveable combustible items such as dry-

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

ing those clearance areas empty assures that nearby

surfaces and objects will not overheat.

The least clearance is required when the connector, as

well as the wall, have heat shields or when a double

wall connector and wall shields are used.

When shields are attached to the stove or chimney

connector, they are mounted away from the stove or

connector surface on noncombustible spacers. Air ﬂow-

ing between the stove (and/or chimney connector) and

attached shields carries away heat. Do not block the air

ﬂow by ﬁlling these gaps with any material.

The shiny shield surface facing the heat source must be

left unpainted, enabling it to reﬂect heat back towards

the stove or connector and away from the wall.

Clearances may be reduced only by means approved

by the regulatory authority, and in accordance with the

clearances listed in this manual.

Because of their restricted air ﬂow and heat retention

characteristics, speciﬁc construction requirements and

special clearances apply to installations into alcoves.

Refer to the diagrams on Page 10, and contact your

Vermont Castings Dealer for details before beginning

an alcove installation.

Wood framing requires pro-

tection from radiant heat

ST247e

Fig. 13 Combustible supporting timbers may lie beneath

ﬁreplace hearths, requiring additional ﬂoor protection.

NOTE: ALCOVE INSTALLATION OF THE ENCORE

IS NOT PERMITTED IN CANADA.

Reducing Clearances Safely with Shields

Clearance requirements are established to meet every

installation possibility, and they involve the combination

of four basic variables:

Wall Shields

One way to reduce clearances is with a wall shield

constructed of 24 gauge or heavier sheet metal, or of

another noncombustible material such as 1/2” (13 mm)

insulation board or common brick “laid on ﬂat,” with the

3¹⁄₂" (90mm) side down.

• When the chimney connector has no listed heat

shield mounted on it.

• When the chimney connector has a listed heat

shield mounted on it.

Shields must be spaced out from the combustible

surface 1" (25 mm) on noncombustible spacers, as in

Figure 14. The spacers should not be directly behind

the stove or chimney connector.

• When the wall has no listed heat shield mounted

on it.

• When the wall has a heat shield mounted on it.

Encore 1450 Non-Catalytic Woodburning Stove

Air must be able to ﬂow between the wall and the

shield. At least 50% of the bottom 1" (25 mm) of the

shield should be open and the shield must be open at

the top. Use metal screening, as in Figure 14, to keep

stray objects from falling behind the shield.

Fireplace Mantel and Trim Shields

A ﬁreplace installation requires special clearance be-

tween the side of the stove and the right and left walls,

between the side of the stove and the decorative side

trim on the ﬁreplace face, and between the top of the

stove and the mantel.

The shield for a top-exit stove must extend 10"

(254 mm) above the top of the stove; for a rear exit

conﬁguration, the shield must be 36” (914 mm) high.

The shield for the chimney connector must be 30” (762

mm) wide, centered behind the pipe; for installations

that use an approved prefabricated chimney to pass

through the ceiling, the chimney connector shield must

stop 1” (25 mm) below the ceiling.

Noncombustible shields installed 1” (25 mm) from the

combustible surface on noncombustible spacers, called

ventilated shields, may be used to reduce clearances.

To protect a mantel from the heat of an Encore in a

ﬁreplace installation, use a custom-made ventilated

mantel shield that is at least 48” (1219 mm) long, that is

centered over the stove. (Fig. 15) Ventilated shields for

side trim must extend the full length of the trim.

Air Flow

An unprotected mantel (“A”, Fig. 16) cannot be more

than 9 (229 mm) deep and must have a minimum clear-

ance of 38” (965 mm), measured from the stove’s top

plate. With a ventilated shield, this clearance may be

reduced safely to 22” (559 mm).

Unprotected top trim (B) protruding 3/4” (19 mm) or less

from the face of the ﬁreplace must be a minimum of 27”

trim shield, this clearance may be reduced safely to 20”

(508 mm).

it is subject to the requirements for wall clearance.

Chimney Connector Heat Shields

Chimney Connector Heat Shields should be used when

it is necessary to protect nearby combustibles from the

heat of the connector. The ceiling above horizontal runs

of chimney connector must be protected as well if the

clearance is inadequate.

1" (25mm)

In top-exiting installations, the connector shield must

extend to a point exactly 36” (914 mm) above the ﬂue

collar or to an elbow in the connector, whichever is less.

If the top-exiting connector extends to the ceiling where

it connects with a prefabricated insulated metal chim-

ney, an additional ceiling heat shield must be installed

that is 24” (610 mm) in diameter and that extends 1” (25

mm) below the ceiling. The ceiling shield must be con-

structed of 24 gauge or heavier sheet metal, and must

be centered on the chimney.

Encore 1450 Non-Catalytic Woodburning Stove

Operation

The Encore NC Controls

Two controls regulate the performance of the Encore

NC: a primary air control supplies oxygen for the

ﬁre, and a damper directs air ﬂow within the stove to

activate and deactivate the non-catalytic combustion

system. Except when starting or reviving a ﬁre, add-

ing fuel or when the stove doors are open, the damper

should always be closed. Operation for extended pe-

riods with the bypass open could result in overﬁring of

the stove causing a possible safety hazard and damage

to the stove.

Low Heat

High Heat

Symbols cast into the stove indicate the correct direc-

tions for opening and closing the controls. The symbols

assume that you are facing the front of the stove.

ST637

Fig. 34 The handle may be positioned anywhere between the

two extremes for different heat levels.

Door Handle

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 before and whenever the griddle

or doors are opened.

Air Control

Lever

The damper is closed when the handle points forward.

Smoke from the ﬁre is directed through the secondary

combustion system where it can be further burned for

greater efﬁciency, before passing up the chimney.

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 34.

The Encore may be used as a ﬁreplace with the

front doors open or removed, BUT only when it is

equipped with an 8” (203 mm) ﬂue collar and only

when the optional spark screen is placed correctly

in the opening to protect against the possibility of

sparks and embers leaving your stove. The test

standard for your stove when it is operated in this

mode is UL 737.

Handle

Use only the Encore spark screen, item #0127, with

your Encore. Encore spark screens are available

from your Vermont Castings’ Dealer.

approved for operation with the front doors open if

equipped with the optional 6” (150 mm) ﬂue collar.

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

latch stub and turn it clockwise. (Fig. 37)

Andirons Help Protect the Glass

Your stove has andirons to keep logs away from the

glass panels. The andirons are essential to maintain

clear ﬁre viewing, and should be left permanently in

place. Since the andirons may slightly hinder refueling

through the front doors, many stove owners will prefer

the convenience of top loading through the griddle.

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.

ST544

Fig. 37 To open the front doors, turn the handle clockwise.

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 are harmful to the stove, chimney system

and the environment. The wood should be 18-20” (457-

610 mm) in length.

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

the handle in the right door ﬁrst clockwise to the open

position and swing the door closed. Finally, push on the

door as you turn the handle counterclockwise (down).

The doors will draw in slightly, and the handle should

offer some resistance as you turn it to the closed posi-

tion.

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.

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. (Fig. 33)

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. The basic difference between hard and

soft wood is their density. Hardwoods, because of their

greater density, burn longer than softwoods and can

increase the time between refuelings.

WARNING: For safety and greatest efﬁciency,

operate your stove only with all doors/griddles fully

closed. The test standard for your stove when it is

operated in this mode is UL 1482.

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

is stored in a dry condition, the better heating and ﬁre

viewing 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 Pages 25-27 for details on how the installation

affects performance.

DO NOT OPERATE THE STOVE WITH THE ASH

DOOR OPEN. OPERATION WITH THE ASH DOOR

OPEN CAN CAUSE AN OVERFIRING CONDITION

TO OCCUR. OVERFIRING THE STOVE IS DANGER-

OUS AND CAN RESULT IN PROPERTY DAMAGE,

INJURY OR LOSS OF LIFE.

Too much draft may cause excessive temperatures in

the Encore, and could even damage the stove. On the

other hand, too little draft can cause backpufﬁng into

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

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.

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 output and

dirty glass.

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.

Starting and Maintaining a Wood Fire

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 help

provide the fresh air needed.

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.

The bypass damper must be open when starting a

ﬁre or when refueling.

Another option for getting more combustion air to the

stove is to duct air directly from outdoors to the stove.

In some areas provisions for outside combustion air are

required in all new construction.

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

not burn garbage. Never use ﬂammable ﬂuids such

as gasoline, gasoline type lantern fuel, kerosene,

charcoal lighter ﬂuid, naptha, engine oil or similar

liquids to start or “freshen up” a ﬁre in this heater.

Keep all such liquids well away from the heater

while it is in use.

Your Encore is equipped to deliver outside air for com-

bustion.

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.

Most installations do not require a large amount of com-

bustion air, especially if adequate draft is available. Do

not attempt to increase the ﬁring of your heater by

altering the air control adjustment range outlined in

these directions.

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.

Encore 1450 Non-Catalytic Woodburning Stove

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 while the heater is in operation. Larger pieces of

charcoal allow more air to circulate under the wood,

resulting in the ﬁre reviving more quickly.

ST265

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:

Fig. 39 Add larger pieces of wood as the ﬁre begins to burn

well.

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

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

top thermometer. Adjust the air control lever as neces-

sary to control the ﬁre.

1. Open the damper.

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

the cement is normal for the ﬁrst few ﬁres.

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.

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, en-

couraging a good draft.

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

ﬁrst), and close the griddle.

4. Allow the stove to regain its “thermal momentum”

before closing the damper. This may take 15--20

minutes.

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.

5. Close the damper and set the air control lever for the

desired heat output. When the surface temperature

reaches 450°F (230°C), adjust the air control for the

amount of heat you desire.

NOTE: If the charcoal bed is relatively thick {about 2”-

3” (52-76 mm)} deep, and if your fuel is well seasoned,

it is possible to add fresh fuel (smaller pieces ﬁrst),

close the door and damper, and reset the primary air

control for the desired heat output within ﬁve minutes.

If your Encore has been broken-in previously using,

continue to build the ﬁre gradually. Add larger wood with

a diameter of 3-4” (76-102 mm). Continue adding split

logs of this size to the briskly-burning ﬁre until there is

a glowing ember bed at least 3” (76 mm) deep. A good

ember bed is necessary for proper functioning of the

combustion system and may take an hour or more to

establish.

WARNING: FIREPLACE STOVES EQUIPPED WITH

DOORS SHOULD BE OPERATED ONLY WITH

DOORS FULLY OPEN OR DOORS FULLY CLOSED.

IF DOORS ARE LEFT PARTLY OPEN, GAS AND

FLAME MAY BE DRAWN OUT OF THE FIREPLACE

STOVE OPENING CREATING RISKS FROM BOTH

FIRE AND SMOKE.

CAUTION: The Encore will be hot while in opera-

tion. Keep children, clothing and furniture away.

Contact may cause skin burns.

DO NOT OVERFIRE THIS HEATER. Overﬁring may

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

age to the stove. If any part of the Encore glows, you

are overﬁring.

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

Ash Removal and Disposal

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

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

ward.

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

and the cavity areas of the stove. 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.

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.

• 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.

Open

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.

ST545

Fig. 41 Turn the handle to the ash pan compartment clock-

wise to open and counterclockwise to close.

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.

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:

• 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.

CAUTION: Never use your household or shop vacuum

cleaner to remove ash from the stove; always remove

and dispose of the ash properly.

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

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

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

curely closed. (Fig. 42)

Encore 1450 Non-Catalytic Woodburning Stove

Draft Management

A stove is part of a system which includes the chim-

ney, the operator, the fuel and the home. Each part of

the system affects how well the stove operates. When

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

works well.

it takes less heat from the stove to heat it up and keep

it warm.

Flue Sizing

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

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

chimney serves an airtight stove, “more” is not “better”;

in fact, it can be a disadvantage. Exhaust gases move

more slowly through larger chimneys and can lose

more heat to the chimney walls. This weakens the draft

strength. If an oversized ﬂue is also outside the house,

the heat it absorbs gets transferred to the outdoor air

and the ﬂue is further cooled.

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 larger 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 depend entirely on the draft

of the chimney.

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

uninsulated liner is a second choice - the liner keeps

the exhaust path restricted to its original size, but the

air around the liner must still be heated. This makes the

warm-up process take longer.

Depending on the features of your installation - (i.e.

metal or masonry chimney installed, 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 is a list of features and their effects.

Pipe & Chimney Layout

Every turn the exhaust 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, and into a verti-

cal chimney. If you are starting from scratch, use this

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

chimney, locate the thimble about midway between the

stove top and the ceiling. This achieves several goals:

it allows the exhaust gases to speed up before turning,

it leaves some pipe in the room for heat transfer, and

gives you long-term ﬂexibility to install a future 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 8 feet (2.4m) of single-

wall stove pipe between the stove and a chimney; lon-

ger runs can cool the exhaust gases enough to cause

draft and creosote problems. Use double-wall stove

pipe for long runs.

Metal Chimney

Most factory-made metal 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. Metal doesn’t have the good looks

of masonry, but it often performs much better.

Single venting

Each ‘airtight’ stove requires its own chimney. If an air-

tight stove is vented to a ﬂue that also serves an open

ﬁreplace, it is easier for the chimney draft to pull air

in through those channels than it is to pull air through

the stove, and performance suffers. Imagine a vacuum

cleaner with a hole in the hose to see the effect here.

In some cases the other appliance can even cause a

negative draft through the airtight, and result in a dan-

gerous draft reversal.

Indoor / Outdoor location

Because the chimney must keep the smoke warm, it is

best to locate it inside the house. The relatively warm

house then surrounds the chimney keeping it warm.

This also means that heat from the chimney walls will

transfer to the house and not be wasted outdoors. An

indoor chimney will not lose its heat to the outdoors, so

Encore 1450 Non-Catalytic Woodburning Stove

Creosote

Draft Testing

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

organic tar that can condense in the ﬂue if the exhaust

gases cool too much. Condensed creosote is volatile,

and can fuel chimney ﬁres if it gets hot enough. All the

factors that affect chimney draft also affect creosote

condensation - so use installation features and opera-

tional steps that encourage good draft and minimize

creosote production.

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.

Test chimney draft with a draft gauge.

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. Canadian law

requires a matching liner to serve any stove or insert

vented through a ﬁreplace chimney; in the US, the Na-

tional Fire Protection Association recommends a liner if

the chimney is more than three times bigger (in square

area) than the outlet on the stove or insert. Some locali-

ties enforce the NFPA guidelines as part of their build-

ing codes.

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 com-

petition between the stove and other equipment that

removes air from the house - 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 equipment. 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, adapters are available to connect

an air duct for outdoor combustion air.

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 and is stored, covered from the

elements. Softwoods burn well, but not as long as hard-

wood. ‘Green’ wood has more moisture in it; it will burn,

but more of the heat from the ﬁre is needed to drive the

extra moisture off the wood. This reduces the amount

of heat that reaches your home and can contribute to a

creosote problem. There are moisture meters available

for ﬁrewood; you can also judge your wood by its ap-

pearance 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.

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 until they

are dense enough and hot enough to ignite. If your

stove back-puffs, you should open the damper to direct

more heat up the chimney to allow the smoke to rise

to the ﬂue more quickly, let more air into the ﬁrebox.

Smaller loads of wood, larger pieces of wood and

avoiding overly dry wood loaded into a very hot stove

may help this problem. If back-pufﬁng persists, contact

your dealer or qualiﬁed chimney sweep to help diag-

nose the problem.

Maintenance

Keep Your Stove Looking New

Removing the Glass

and Working Its Best

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.

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

cool completely before beginning any maintenance

procedure.

Care of the Cast Iron Surface

2. Remove the screws that hold the retainer clips in

place, and remove the clips.

An occasional dusting with a dry rag will keep the painted

cast iron of your Encore looking new.

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

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

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

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

with a wire brush to remove any loose paint or dust.

Remove the griddle and set it aside.

Installing the Glass

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.

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.

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.

Care of the Porcelain Enamel Surface

Right Door

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.

2. Secure the glass on both doors with the retainer

clips, but leave the screws a little loose.

Replace Broken Glass Immediately

3. Gradually tighten all the screws by hand a little at

a time in order to apply even pressure to the glass

panel.

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

damaged.

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.

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.

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.

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.

doors to each other.

Adjust the Door Latches

If you need to change a gasket, ﬁrst obtain an appropri-

ate replacement from your Vermont Castings’ Autho-

rized Dealer.

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.

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.

Over time, the gasket around the doors will compress

and the latches may need adjustment.

The procedure for replacing gaskets is the same re-

gardless of the gasket location. Follow these steps:

To adjust the latches on the doors, 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 repeated

small adjustments until the setting is right.

1. Remove the existing gasket by grasping an end and

pulling ﬁrmly.

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

the channel of any remaining cement or bits of gasket.

(Fig. 47)

5/16” diameter gasket seals the following parts:

• The ﬂue collar to the stove back

• The lower ﬁreback to the sides

• All connections between the major stove plates

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

from unraveling.

The Chimney System

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.

5. Lay an unbroken 1/8” (3mm) bead of gasket cement

in the newly-cleaned channel.

6. Starting at one end, press the gasket into the chan-

nel. (Fig. 47) Ensure a good joint where the gasket

meets before trimming any excess. Do not overlap the

gasket ends or leave ends with ragged edges.

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 —1/8” (3mm) or more — it

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

Sto

ST561

To reduce the amount of creosote that may form, re-

member to provide adequate air for combustion and to

strive for small, intense ﬁres rather than large, smolder-

ing ones.

Fig. 47 Lay a bead of gasket cement then press gasket in

place.

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).

You can never be too safe. Contact your local ﬁre

authority for information on what to do in the event of

a chimney ﬁre, and have a clearly understood plan on

how to handle one.

8. Clean any excess cement from around the chan-

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

thoroughly.

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.

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 28.

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.

All Gasketed Construction

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.

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.

If you cannot inspect or clean the chimney yourself,

contact your local Vermont Castings’ Dealer or a profes-

sional chimney sweep.

Encore 1450 Non-Catalytic Woodburning Stove

Maintenance Schedule

The Stove

The Chimney Connector

TWO WEEKS:

• Inspect the chimney connector and chimney. Clean if

necessary.

DAILY:

• Clear any ash build-up from around the air holes and

combustion ﬂow path in the lower ﬁreback.

TWO MONTHS:

• Inspect the chimney and chimney connector. Pay

particular attention to the horizontal runs of chimney

connector, and the elbows. Clean the system if nec-

essary.

• Ashes should be removed before they reach the top

of the ash pan. Check accumulation at least once a

day.

ANNUAL SPRING CLEANING:

• Keep the area around the stove clear of any combus-

tible materials such as wood, furniture or clothing.

TWO MONTHS:

• Disassemble the chimney connector and take it

outdoors for inspection and cleaning. Replace weak

sections of connector.

• Inspect the chimney for signs of deterioration. Re-

pairs to a masonry chimney should be made by a

professional mason. Replace damaged sections of

prefabricated chimney. Your local Vermont Castings

dealer or a chimney sweep can help determine when

replacement is necessary.

• Check door handle to be sure it is working properly.

Gasketing becomes compressed after a period of

time. Adjust handle tightness if necessary.

• Check leg bolts and heat shield screws; tighten if

necessary.

ANNUAL SPRING CLEANING:

• Thoroughly clean the chimney.

• Check gasketing for wear, and replace if necessary.

• Remove ashes from the ash pan and replace with a

moisture absorbing material (such as kitty litter) to

keep the interior of the stove dry.

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

pipe heat shields if your stove is equipped with them.

Clean surfaces are better heat reﬂectors than dirty

surfaces.

• Touch up the black paint.

• Inspect for and remove ash build-up behind the com-

bustion package. This should be done in conjunction

with annual cleaning of the chimney connector since

this inspection is most conveniently done through the

ﬂue collar opening. Inspect the passages to either

side of the combustion package (a mirror will be

helpful) and vacuum away ash using a ﬂexible vacu-

um hose inserted into each passage. Care should be

taken not to damage the white ﬁbrous material in this

rear chamber. (Fig. 48)

Encore 1450 Non-Catalytic Woodburning Stove

LIMITED LIFETIME Warranty

For Vermont Castings Encore, Non-Catalytic Wood Stove

Limited Lifetime Warranty

CFM Corporation warrants that all refractory brick and

material used in this product will be warranted against

deterioration not resulting from physical damage or

overloading of the woodstove for the lifetime of this

product. This coverage includes the components of

the EverBurn System: “shoe, fountain, and ﬁreback.

Coverage is provided only to the original purchaser.

common carrier. Contact Vermont Castings Authorized

Dealer from whom you purchased your stove or CFM

Corporation if the purchase was direct. (Do not oper-

ate the stove as this may negate the ability to process

the claim with the carrier).

6. Claims are not valid where the installation does not

conform to local building and ﬁre codes or, in their ab-

sence, to the recommendations in our Owners Guide.

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

humidity environment, can be corrosive to the porce-

lain 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 3 Year Warranty

All cast iron parts are warranted for a period of three

years against breakage, cracking or burn-through.

Limited 1 Year Warranty

The following part of the woodburning stove are

warranted to be free of defects in material and work-

manship for a period of one year from the date you

receive it: The handles, glass door panels, door

gasketing and porcelain ﬁnish. Any of these items

found to be defective will be repaired or replaced at

no charge, upon the return of the part with postage

prepaid to a Vermont Castings Authorized Dealer.

8. CFM Corporation shall have no obligation to enhance

or update any unit once manufactured.

IN NO EVENT SHALL CFM Corporation BE LIABLE FOR

INCIDENTAL AND CONSEQUENTIAL DAMAGES. ALL

IMPLIED WARRANTIES, INCLUDING THE IMPLIED

WARRANTIES OF MERCHANTABILITY AND FITNESS,

ARE LIMITED TO THE DURATION OF THIS WRITTEN

WARRANTY. THIS WARRANTY SUPERCEDES ALL OTHER

ORAL OR WRITTEN WARRANTIES.

Any parts 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.

Some states do not allow the exclusion or limitations of

incidental and consequential damages or limitations on

how long an implied warranty lasts, so the above limi-

tations may not apply to you. This warranty gives you

speciﬁc rights and you may have other rights, which vary

from state to state.

Exclusions & Limitations

1. This warranty is non-transferable.

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 pig-

ments has burned off. Overﬁring in enamel stoves is

identiﬁed by bubbling, cracking, chipping and discolor-

ation 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 Owners Guide, nor does it cover a

stove which has been modiﬁed unless authorized by a

CFM Corporation representative in writing. This war-

ranty does not cover damage to the stove caused by

burning salt saturated wood, chemically treated wood,

or any fuel not recommended in the Owners Guide.

4. This warranty does not cover a stove repaired by

someone other than a Vermont Castings Authorized

Dealer.

1. Name, address, and telephone number of the pur-

chaser

2. Date of Purchase.

3. Serial number from the label on the back

4. Nature of the defect or damage.

5. Any relevant information or circumstances, e.g., instal-

lation, mode of operation when defect was noted.

A warranty claim will then start in process. CFM Corpo-

ration reserves the right to withhold ﬁnal approval of a

warranty claim pending a visual inspection of the defect

by authorized representatives.

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

by this warranty but is subject to a claim against the
