Planning Information
Planning an installation is very important to ensure
safety and to save time and money. An installer must
predetermine where a fireplace will be set and how the
chimney system will be run.
5. No more than 2 offsets (4 total 30° elbows in U.S./or
2 total 45° elbows in Canada) per fireplace may be
used.
6. A guy wire stabilizer is required for chimneys extend-
ing more than 6’ (1.8m) above a roof line.
NOTE: If installing the EWF36CFTK at a later date and
if the hearth is being raised in front of the firepalce, the
fireplace must be raised to the same height.
The Ten Foot Rule
Major U.S. building codes specify a minimum chimney
height above the roof top. The “Ten Foot Rule” is a fire
safety rule and not a draft rule. To ensure proper draft,
it is recommended that you always meet or exceed the
“Ten Foot Rule,” especially when installing a termination
on a high pitch roof. (Fig. 5)
Mounting the Fireplace
The fireplace is shipped with lifting handles attached to
each side with lifting straps. NOTE: The lifting straps
are intended for ligting unit off of the skid and final po-
sitioning. Unit should remain on skid until final position-
ing. After fireplace is in position, the lifting handle and
straps may be removed or left in place.
The key points of the “Ten Foot Rule” are:
1. If the horizontal distance from the chimney to the
peak of the roof is 10’ (3m) or less, the top of the
chimney must be at least 2’ (610mm) above the peak
of the roof, but never less than 3’ (914mm) in height
above the highest point where it passes through the
roof.
A fireplace may only be mounted on the following sur-
faces:
1. A flat combustible surface.
2. A raised wooden platform.
3. A concrete block or other solid object placed beneath
each of the four (4) corners of the fireplace.
2. If a horizontal distance from the chimney to the peak
of the roof is more than 10’ (3m), a chimney height
reference point is established that is on the surface
of the roof a distance of 10’ (3m) from the chimney in
a horizontal plane. The top of the chimney must be
at least 2’ (610mm) above the reference point, but
never less than 3’ (914mm) in height above the high-
est point where it passes through the roof.
The fireplace must be spaced 1” from a combustible
back wall and 1” from a combustible side wall or sup-
port. (Page 13, Fig. 17)

heights.
Fig. 5 Ten Foot Rule illustration.
In planning a chimney system, it is important to know:
1. The height of a chimney is measured from the hearth
to the exit point on the termination.
2. A chimney cannot be offset more than 30° from a
vertical plane.
3. A chimney may run straight up or it may be neces-
sary to offset it to avoid obstructions.
4. The maximum length of an angled run (total chimney
system) is 20 feet.

Chimney Supports
Installation
The chimney system is supported by the fireplace for
vertical chimney heights less than 30’ (9m) above the
hearth. Chimney supports are required if the vertical
height exceeds 30’ (9m). Locate chimney supports
at ceiling holes or other structural framing at 30’ (9m)
heights. Spacing between chimney supports must not
exceed 30’ (9m). Use Chimney Support Model TCS8A.
(NOTE: The TCS8A cannot be mounted directly to
the fireplace.) Support provided by elbow straps fulfills
the support requirement only if they are spaced as pre-
viously described. (A chimney support is 2¹⁄₂" (64mm)
long when installed.)
Insulating Fireplace Enclosure
for Cold Climates
If you live in a cold climate, it is not required but
highly recommended that you insulate fireplace
enclosure to eliminate cold air penetration as much as
possible.
Insulate base of fireplace with a noncombustible
insulation rated for a minimum of 300° F. Insulating
is very important for outside wall installations over
a concrete slab. If fireplace is installed on a platform,
insulation should be placed on top of the platform
before fireplace is set. (Fig. 7)
Angled chimney runs require a support every 6’ (1.8m)
in addition to the elbow straps. Chimney supports are
used for this function. (Fig. 6)
When a fireplace is installed in a chase or on an
outside wall, enclosure should be treated like any
outside wall in a home. Insulation should be installed
on the inside wall as well as the outside wall(s). In a
chase, it is also a good idea to install a firestop at the
first ceiling level above the fireplace and enclose the
chase with sheeting material. Insulation may then be
installed above sheeting material to assure the space
around the fireplace is totally protected. (Fig. 2)
Chimney Sup-
port Strap
When installing the chimney, DO NOT caulk between
outer pipe and firestop. It is vital that some air be al-
lowed to flow through this very thin gap.
TCS8A
CAUTION: When installing a fireplace in an insu-
lated enclosure, be sure all required air spaces
are maintained. (Page 13, Fig. 17)
FP284a
Fig. 6 Chimney support installation.
Chase Installation
A chase is a vertical box-like structure which encloses
the fireplace and/or chimney. Chases are typically built
on the outside of the house with fireplace opening cut
into the outer wall of a room. (Page 5, Fig. 2)
If you need help in determining fireplace location or how
the chimney system should be run, contact your Ver-
mont Castings dealer for assistance.

Framing
Chimney Centerline
Actual Centerpoint
Framing can be constructed before or after the fireplace
is set in place, however, most installers build the frame
before setting the fireplace.
9���"
(241mm)
Frame fireplace with 2 x 4 lumber or heavier materi-
als. Refer to framing dimensions in Figure 1 for basic
fireplace specifications.
NOTE: Framing should be positioned to accommodate
wall covering and fireplace facing material.
Plumb Line
Plumb Bob
EB1 (Receptacle) Hookup
Option for Circulating Models Only
Wiring should be installed by a certified electrician.
Turn off circuit breaker before wiring models.
Imaginary Cen-
terpoint
Once fireplace is secured, complete wiring the fan kit.
Remove knockout in the center of the back of the EB1
and install listed cable clamps. Feed electrical wire
through listed cable clamp leaving approximately six (6)
inches of wire exposed through the EB1. Secure listed
cable clamp to the wire.
Attach white wire from power source to one (1) wire
of receptacle and secure with nut. Attach black wire
from power source to the other wire of receptacle and
secure with nut. Be sure nuts are secured tightly.
Secure EB1 assembly to inside of electrical box cover-
plate using two screws. Attach cover to face of the EB1
while being careful to position excess wire completely
within the EB1, then attach coverplate to fireplace.
Chimney Set-Up
Since you have already planned the chimney run, you
should know exactly how the installation is to be ac-
complished - how much pipe is required, the number of
elbows, if any, and type of termination to be used.
FPC556a
Fig. 8 Locate centerline of chimney with plumb line.
Offset Installation
CAUTION: Report to your dealer any parts damaged
in shipment, specifically check the end connection of
chimney sections and elbows.
In order to clear an obstruction, it may be necessary to
offset chimney from vertical. This is accomplished by
using elbows. Use the 30˚ Offset Elbow table on Page 6
to determine proper offset and parts required.
NOTE: The EWF36A fireplace must use CFM Corpora-
tion model triple wall 8” chimney components only. The
installation procedure described in this manual applies
only to this system.
Each offset requires two (2) elbows. The second elbow
is equipped with support straps. It is very important to
install the second elbow in each offset as close to the
ceiling or support as possible so that the elbow straps
can be secured to framing members to help support the
weight of the chimney.
Straight-Up Chimney Installation
To mark the centerline of the flue, put the fireplace
in final position and measure out from the wall: 9¹⁄₂"
(241mm). Mark a spot on the ceiling directly above the
fireplace. Draw a line parallel to the back wall through
this mark. (Fig. 8)
Determine offset distance of your chimney arrangement
from centerline of fireplace to centerline of chimney
where it is to pass through ceiling.
Locate center point of the chimney on ceiling as though
a straight up chimney arrangement is to be used. Mea-
sure your offset dimension from straight up chimney
center point on ceiling.
Using a plumb bob positioned directly over center point
of fireplace flue collar, mark the ceiling to establish the
chimney center point. (Fig. 8)

Securing the Fireplace
Two (2) nailing flanges are supplied with the fireplace.
To level the box and secure it firmly in place, remove
the nailing flanges from the hearth and install at the
sides of the fireplace as shown in Figure 12.
Slide fireplace into position.
Safety strips are used to ensure that any combustible
materials in front of the fireplace are protected even
though a noncombustible hearth extension is required.
When the finished extended hearth is added, the top
of the finished hearth must be flush with the bottom of
the fireplace. “Z” shaped metal safety strips have been
supplied with the fireplace and are required for instal-
lation. The safety strips provided have a 1” offset. For
applications with a greater offset, “Z” shaped strips will
have to be fabricated of metal. Overlap safety strips at
least 1/2” to provide a positive joint. The safety strips
must also extend at least 1¹⁄₂” (38mm) beyond the sides
of the fireplace. (Fig. 11)

Duct run must be limited to a maximum distance of 40
feet from the fireplace pipe collar to duct termination.
This will provide the least restriction to air flow. No more
than four (4) 90° elbows can be used. Duct run may
be horizontal, vertical, inclined or any combination of
these. Vertical duct runs must be at least three (3) feet
below the fireplace chimney flue exit. (Fig. 13) You are
now ready to install the AK-MST Outside Air Kit.

compete for air flow with exhaust fans, gas vent hoods
or other air consuming devices or appliances. It must
not be obstructed by rafters, insulation materials or
other obstructions. The less restrictive the air supply,
the better the AK-MST will perform.

future use.
Installing the Chimney System
Start by attaching the first chimney section to the collar
on top of the fireplace.
2. Slide the two (2) air duct assemblies provided with
the unit into the openings on each side of the unit.
(Fig. 14)
Install the pipe as pictured in Figure 16. When you
get a good lock, you will hear the pipe clearly snap
together. Once sections are snap-locked in place, it is
extremely difficult to get them apart. Make sure the
pipe is firmly snapped and locked together as each
pipe section is mounted.
3. Attach the air duct assemblies to the inside panel
with four (4) screws removed in Step 1. (fig. 14)
When installing elbows, only outer pipe will snap- lock.
Middle pipes simply slide into position. Be sure to
always attach straps on upper elbow to a structural
framing member. (Fig. 17)
Air Duct Assembly
Continue installing the pipe as required until pipe is
installed up through the ceiling. At this point, you must
install a firestop spacer.

Canadian Requirements
Installing the Firestop Spacer
in the Ceiling Hole
for Insulation Shield
In Canada, an attic insulation shield is required to
prevent attic insulaiton from contacxting the chimney
section. NOTE: If the attic insulation shield is used, the
firestop is not required in the attic installation. Framing
dimensions fr the chimney hole should measure 17¹⁄₂” x
17¹⁄₂” (445 x 445 mm). An attic shield MUST be installed
on top of attic joists (above the floor level). (Fig. 19)
A firestop spacer is used to keep pipe spaced properly
and required for safety.
Nail the firestop spacer (at each corner) to the framing
members of the ceiling hole. NOTE: A firestop spacer
is not required at the roof.
Hole sizes listed in Figure 9 for angled firestop spacers
provide minimum required air space to chimney pipe for
ceiling thickness up to 8” (203 mm). When combined
thickness of ceiling material, ceiling joists and flooring
material exceeds 8” (203 mm), adjustments must be
made in framing to assure that minimum air spaces to
chimney are maintained.
NOTE: In the U.S., it is a good idea, although not al-
ways required, to install an attic insulation shield where
blown-in insulation is planned to be used in the atic.

Continue Installing Pipe to Complete Run
DO NOT put any sealant around the area where the
outer pipe slides through the firestop spacer. If you seal
this area, it may cause a fire hazard.
Continue attaching pipe sections to complete system
to next level always being careful that the pipe is firmly
snapped locked in place before proceeding to next pipe
section.

Chimney Supports
Firestop Spacer
If chimney supports are required, they are installed the
same as elbows. Nail chimney support straps to adja-
cent structural framing, as shown on Figure 16. Bend
straps as necessary and make sure they are secure so
they will support the weight of the chimney. A chimney
support is 2¹⁄₂" (64 mm) long when installed. Consider
this dimension when determining how many straight
chimney sections are needed.
Joist
NOTE: If the attic insulation shield is used, the
firestop is not required in the attic installation.

Penetrating the Roof
Installing Chimney in a Chase
Run pipe to roofline. Since chimney system must be
vented to the out-of-doors, you must use an approved
CFM Corporation termination.
Refer to Figure 2, Page 5 for an illustration of a typical
chase installation.
CAUTION: Treatment of firestop spacers and construc-
tion of chase may vary with type of building. These
instructions are not a substitute for local building codes.
You must check your local building codes to determine
specific requirements for your city or state. NOTE:
Other building materials may be required in addition to
CFM Corporation Firestop Spacers.
If a chase is used, refer to the installation manual pro-
vided with the termination cap.
Locate Chimney Centerpoint on Roof
Use same procedure detailed in locating center point of
the flue system.
Drive a nail up through roof at the center point. This will
determine center point on outside of the roof.
Finishing
CAUTION: All joints between the finished wall and
the fireplace surround (steel front) must be sealed with
noncombustible material to prevent cold air leakage into
the room. (Fig. 20)
Cut and Frame Roof Hole
Size of roof hole varies with the type of chimney ter-
mination installed. Refer to installation instructions
provided with CFM Corporation chimney termination to
find correct size of roof hole.
NOTE: No material may cover black cast face.
Air Space Clearances
There must be a 2” (51 mm) air space between out-
ermost portion of chimney sections and any adjacent
combustible surfaces. (Combustible surfaces include
burnable materials such as: ceiling members, joists,
flooring, combustible insulation and roof structures.)
Combustible framing material MUST NOT
penetrate AIR SPACE (shaded areas)

WARNING: Do not pack required air spaces with
insulation or other materials.

Standoff
Mark an outline of the roof hole around the center of the
point nail. NOTE: Hole dimensions given in the chim-
ney top installation instructions are horizontal dimen-
sions; therefore, the hole size must be marked on the
roof accordingly.

Space to Sides
Cover the opening of the installed chimney so debris
cannot get into the system.
Firestop
Cut and frame the hole. It is good practice to use fram-
ing lumber that is the same size as the rafters. Install
the frame securely because the chimney top and flash-
ing anchored to the frame must be able to withstand
heavy winds.

Side Wall Protection
Mantels
Adjacent combustible side walls that are within mini-
mum dimensions shown in Figure 25 of the fireplace
opening must be protected with CFM Corporation Wall
Shield Model SP40 or a specifically built wall shield
described in Figure 20.
The height that a combustible mantel is fitted above the
fireplace is dependent on the depth of the mantel. This
also applies to the distance between the mantel leg (if
fitted) and the fireplace.
For the correct mounting heights and widths, refer to
Figures 22 and 23. When using paint or lacquer to finish
the mantel, such paint or lacquer must be heat resistant
to prevent discoloration.
The special wall shield design described in Figure 20 is
an alternate method of adding protection to side walls
and can be used in place of the SP40 with the same
wall clearances specified for the SP40. Rt must =1.85

Operation
Damper
Attach Handles
Primary Air Control
The fallaway handles are used to open and close the
front doors. Remove after each use so they will not get
hot. Keep in convenient location for each use. (Fig. 27)
Assemble the primary air control and damper handles
by passing the 3³⁄₈” screw through the ceramic shaft
and into the bright metal hub. Tighten carefully until
snug. Do not overtighten. Ceramic handle could crack.
(Fig. 28)

Fallaway Handle
Fig. 29 EWF36A controls.
The primary air control is located in the upper left
corner of the unit. (Fig. 27) It is the primary source of
air for starting, maintaining, and reviving the fire.
FP1397
Generally, more air entering the fireplace makes the fire
burn hotter and faster, while less air prolongs the burn.
Fig. 27 Insert fallaway handles into door handle stubs.
The air supply is open to the maximum when the control
lever is rotated clockwise, and closed when rotated
counterclockwise. To vary the burn rate, adjust the con-
trol to the desired position in between these extremes;
opening the primary air control makes the unit burn
hotter. Closing the control slows the unit down. You may
adjust to any position you desire.

The damper directs air flow within the fireplace.
Screw
The damper is operated by moving the lever located
in the upper right corner of the unit. It has two posi-
tions: Open to start or revive the fire and closed, for
normal operation and to control burn rate. The damper
is open when the lever is fully rotated counterclockwise
and pulled out and closed when pushed in. When the
damper is in the open position, with the lever pulled out,
and rotated fully in the clockwise direction, the handle
can ‘telescope’ back without closing the damper or any
damper movement. There are no intermediate settings
for the damper.
FP1396
Fig. 28 Assemble primary air control and damper handles.
EWF36A Controls
Three controls regulate the performance of the
EWF36A fireplace: A primary air control supplies oxy-
gen for the fire, the damper directs air flow within the
fireplace and a variable-speed fan control, or rheostat,
regulates the warm air flow into the room. (Fig. 29)
Primary Air Control
NOTE: Full clockwise or counterclockwise movement of
the damper handle is approximately 50°.
A single air control regulates the amount of heat the fire
will produce and how long it will burn.
NOTE: Always open the damper before opening the
doors. Close damper to set burn rate.

Vermont Castings EWF36A
Use the Air Control Settings
The Fan
that Work Best for You
Heated air from the fireplace is forced into the room by
an internal fan. The control for the fan is in the right
corner of the unit.
No single air control setting will fit every situation. Each
installation will differ depending on the quality of the
fuel, the amount of heat desired, and how long you wish
the fire to burn.
“Off” is to the far left.
“High” is just to the right of “Off.”
“Low” is to the far right.
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.
Variable adjustment of the fans is possible with any set-
ting between “high” and “low.”
For best results, coordinate fan speed with the setting
of the primary air control. For example, when the air
control lever is set at “low,” also set the fan at “low.”
With the air control set for maximum heat, set the fan at
“high.”
Too much draft may cause excessive temperatures
in the fireplace. On the other hand, too little draft can
cause backpuffing into the room and/or the “plugging” of
the chimney or combustor.
Glass Doors
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 part of the EWF36A front. A
sign of inadequate draft is smoke leaking into the room
through the stove or chimney connector joints, low heat,
and dirty glass.
The EWF36A is intended for use with the doors fully
closed or fully open only when optional spark screen
is installed. (Fig. 30) NOTE: When operated with the
doors open and spark screen in place, the damper
MUST be in the open position.
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.
Another option for getting more combustion air to the
stove is to duct air directly from the outside to the stove.
In fact, in some areas provisions for outside combustion
air are required in all new construction.

Your EWF36A is designed so that it is possible to
incorporate outside air for combustion. Directions for
installing the optional AK-MST outside air ducts are
included with the kits and beginning on Page 11 of this
instruction.
Burn Only High-Quality Wood
The EWF36A is designed to burn natural wood only; do
not burn fuels other than that for which it was designed.
You will enjoy the best results when burning wood that
has been adequately air-dried. Avoid burning “green”
wood that has not been properly seasoned.
When first using the stove, keep track of the settings
of the air controls. 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.
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.
For areas that do not have a supply of hardwood, com-
monly burned softwoods include tamarack, yellow pine,
white pine, Eastern red cedar, fir, and redwood. These
too should be properly dried. Your EWF36A will accept
wood up to 24” (610 mm). Longer wood pieces work
better than short ones.
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.
Wood should be stored under cover to maintain dry-
ness, and should be dried at least six months for
optimum heating and fire-viewing performance. 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.

Vermont Castings EWF36A
5. Once a good ember bed of at least 2-3” (51-76 mm)
has formed, let the fire burn hot for an additional ten
to fifteen minutes.
Starting and Maintaining a Wood Fire
Burn solid wood fuel only in the EWF36A, and burn
it directly on the grate. Do not elevate the fuel. Do
not burn coal or other fuels.
6. Close the damper and the primary air control to a
medium-low setting as described on Page 18. The
fire volume will diminish immediately, but the fire-
place will continue to heat up. Maintain control of
the fire using the primary air control, and remember:
reduce the setting for less heat, increase the set-
ting for more heat. Refer to the air control settings
information on Page 18 for recommended settings at
different burn rates.
Minimize thermal stress by allowing the plates to adjust
gradually during an initial break-in fire by following
Steps 1-3 below.
WARNING: Operate your EWF36A only with the
doors fully closed. If the door is left partially open,
gas and flame may be drawn out of the fireplace
opening, creating risks of both fire and smoke.
1. Open the primary air control fully.
2. Open the damper.
DO NOT OVERFIRE THIS HEATER. Overfiring may
cause a house fire, or can result in permanent damage
to the stove. If an exterior part of the EWF36A glows,
you are overfiring.
3. Lay some crumpled newspapers on the bottom
grate. Place on the paper six or eight pieces of dry,
finely-split kindling. On the kindling lay two or three
larger sticks of split dry wood approximately 1-2”
(25-51 mm).
Reloading and Reviving a Wood Fire
• Open the damper and set the air control on “High,”
and wait at least fifteen seconds for the draft to
increase. Open the door slowly.
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.
• Check the ash level, and empty the ash pan if nec-
essary. Replace the pan.
Also, never use gasoline-type lantern fuel, kerosene,
charcoal lighter fluid, or similar liquids to start or “fresh-
en up” a fire in this heater. Keep all such liquids well
away from the heater while it is in use.
• Add the fuel, smaller pieces first. If it is necessary
to use wood smaller than the 24” (610mm) optimum
size, be sure to fill the firebox as completely as pos-
sible by loading the wood pieces alternately on the
left and right. Split wood will fill the firebox more
completely and reduce the frequency of reloading.
4. Light the newspaper and close the door. Gradually
build up the fire by adding a few 3-5” (80-120 mm)
diameter splits.
If you have an ember bed of at least 2-3” (51-76 mm),
leave the thermostat set on “high” for 10-15 minutes. If
the ember bed is less than 2-3” (51-76 mm), you may
have to let it burn longer.
If this is your initial break-in fire, let the fire burn brightly,
but not to excess. Control the fire’s intensity by adjust-
ing the air control lever. After an hour or so stop adding
wood so that the fire dies out gradually.
Finally, close the damper and adjust the air control and
fan speed for your desired heat level.
For ongoing operation after the initial break-in, continue
to add a few sticks at a time of a progressively larger
size. Continue until you have a live ember bed at least
2-3” (51-76 mm) deep. This may take an hour or longer.
NOTE: If the charcoal bed is relatively thick and your
fuel is well-seasoned, it is possible to add fresh fuel
(smaller pieces first), close the door and damper, and
reset the air control within five minutes.
CAUTION: THE EWF36A IS HOT WHILE IN OPERA-
TION! KEEP CHILDREN, CLOTHING, AND FURNI-
TURE AWAY. CONTACT MAY CAUSE SKIN BURNS.
Special Tactics for Cold-Climate Heating
NOTE: Some chimneys need to be “primed,” or
warmed up, before they will draw sufficiently to open
the damper. 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 should heat the chimney enough to initi-
ate a draft.
The EWF36A is capable of producing in excess of
100,000 Btu’s/hour and heating an area of up to 2,500
sq. ft.(558 sq. m) However, many factors affect heating
performance and can influence the extent to which the
EWF36A can heat a given area.
A well-insulated home, located in a moderate climate
and with the EWF36A Fireplace located centrally in
an open floor plan, will be easier to heat than a drafty
home in the far north in which the EWF36A is installed
on an exterior wall at the end of a long house.
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.

Vermont Castings EWF36A
Different results may be experienced even in the same
installation if you switch from burning good, dry wood to
wood that is partially rotted or inadequately seasoned.
Empty the ash pans regularly, typically every one to
three days. The frequency will vary depending on how
you operate your EWF36A: If you burn more wood at
higher heat output settings, and ash will accumulate
faster.
To compensate for these factors in cold climates, it may
be necessary to operate the EWF36A with the air con-
trol set to a higher level more of the time.
Ash should be removed frequently and placed outdoors
in a metal container with a tight-fitting lid. The closed
container of ash should be placed on a noncombustible
floor or on the ground, well away from all combustible
materials, pending final disposal. If the ash is disposed
of by burial in soil or otherwise locally dispersed, it
should be retained in the closed container until all cin-
ders have thoroughly cooled. Wood ash may be used
as a garden fertilizer.
Remove and Store Ash Safely
Check the ash pan before reloading the stove, and
empty if necessary using the following procedure:
•
•
•
Open the damper.
Open the load door.
Remove the ash pans from under the hearth
brick. The EWF comes with a cover for the ash
pan. To install this cover, hold just above the ash
pans with the handle on the cover closest to you.
Slide the cover onto the top of the pan as you
pull the pan out. As the pan slides out, the flange
on the back of the cover should slide into the slot
in the back of the ash pan and the flange on the
front of the cover will slide over the handle on
the ash pan. CAUTION: Do not pull the pan out
too far before the cover engages the slot. Ash
may contain hot coals and must be treated with
extreme care. Hold the covered ash pan with both
hands to avoid dropping or spilling the ashes.
Take the pans outdoors and empty the ash into
an ash container.
CAUTION: Never use your household or shop vacuum
cleaner to remove ash from the fireplace; always re-
move and dispose of the ash properly.
•
•
Before replacing the ash pan, clear away any ash
that has spilled over the sides and back of the
pan.
•
Replace the ash pans and front door.

tance, the gasket isn’t snug enough at that spot. Con-
tinue to make small adjustments until the setting is right.
Ash residue that accumulates on the glass should be
removed periodically to prevent etching. To clean the
glass, follow this procedure:
If additional adjusting of the latch does not enable the
door to seal sufficiently in one area, try “adjusting” the
gasket in that area. Pack more cement or a smaller
diameter gasket into the channel beneath the gasket so
that the main gasket is raised and makes contact with
the door frame. This procedure should solve the prob-
lem. If the gasket needs replacing, follow the directions
beginning on Page 23.
•
•
Be sure the glass is completely cool.
Cleaning with water will work in most cases. Use
a glass cleaner especially made for this purpose
only if deposits are especially heavy. (If heavy
deposits are a frequent occurrence, however,
evaluate your operating techniques.)
•
•
Rinse the glass thoroughly.
Dry the glass completely.
The Catalytic Element
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.
NOTE: The EWF36A glass is coated with a special
material on the outside that helps reflect heat back
into the fire chamber. Do not attempt to remove
this coating.
Adjust the Door Latch Periodically
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 de-
termine when it needs to be replaced. A nonfunctional
combustor will result in a loss of heating efficiency, and
an increase in creosote and emissions.
The front door of the fireplace should close securely to
prevent accidental opening and should close tightly to
prevent air from leaking into the fire chamber. The door
handles will be positioned vertically when the door is
closed.
Over a period of time, the gasket around the door will
compress and the latch may need adjustment. To ad-
just the handle, follow this procedure (Fig. 31):
Inspection and Cleaning
1. Loosen the small lock nut with a wrench.
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 performances
as outlined in the next section.
2. Extend the striker screw one turn by turning it with
an Allen wrench.
3. Retighten the lock nut, while at the same time hold-
ing the striker screw with the Allen wrench to prevent
its turning.
Test the door seal. Close the door on a dollar bill and
attempt to pull it free. If the bill is freed with little resis-

Vermont Castings EWF36A
When to Suspect a Combustor Problem
Wedge (In Place)
The best way to evaluate the performance of your
EWF36A’s combustor is to observe the amount of smoke
leaving the chimney - both when the combustor has
“lighted-off” and when it has not. Follow these steps:
• With a fire going and the combustor properly activat-
ed, with the damper closed to route smoke through
it as described in the Operation Section, go outside
and observe the smoke leaving the chimney.
Wedge
Catalyst As-
sembly

• Then, open the stove damper and once again check
the smoke leaving the chimney.
Fig. 32 Carefully tap out the wedges, then slide the Catalyst
Assembly out of fireplace.
You should see significantly more smoke when the
stove damper is open and exhaust does not pass
through the combustor. However, be careful not to
confuse smoke with steam from wet wood. Steam dis-
sipates in the air quickly; smoke does not.
sages. Such abrasion can scrape the thin coating of
platinum (the catalyst) off the ceramic base, shorten-
ing the catalyst’s life and reducing its effectiveness.
5. 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.
If this test indicates a problem, consider other possible
factors as well, such as the weather or a change in the
quality of your fuel. In warm weather, 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.
6. If the element is in good condition and clean, rein-
stall it in the fireplace.
Burning “green” (insufficiently seasoned) wood will
result in poorer performance than burning properly
seasoned fuel. You may have to run your fireplace hot-
ter (more air) to achieve acceptable performance using
green or wet wood.
Operate the stove in your usual manner for two weeks,
inspecting the chimney and the chimney connector
frequently during this period.
If creosote does not build up as fast, it is likely that 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
that proper performance continues.
Also consider any changes in your operating routine.
Once you have ruled out any other possible causes for
a decline in performance, inspect and clean the com-
bustor if necessary.
If you continue to find a significant creosote buildup or if
you continue to see excessive smoke form the chimney,
the catalytic element will need to be replaced. Contact
your nearest Vermont Castings authorized dealer.
Inspecting the Combustor
Use a flashlight and mirror, if necessary, to examine
the combustor. If no fly ash or damage is visible, the
inspection is complete. If closer examination, cleaning
or replacing is needed, go to the next section.
NOTE: Use only the replacement catalyst supplied by a
Vermont Castings dealer.
Removing, Cleaning or
Replacing the Combustor
How to Replace Gaskets
The EWF36A uses rope-type fiberglass gaskets to
make a tight seal between some parts. With use, par-
ticularly on those parts that move, gaskets can become
brittle and compressed and can begin to lose their ef-
fectiveness. These will need periodic replacement.
1. Allow fireplace to cool.
2. Tap the left and right wedges back and remove. (Fig.
32)
3. Carefully slide catalyst assembly to the back of the
fireplace and out of the retaining brackets.
All of the gaskets used are made of fiberglass. The
four sizes of replaceable gasket are listed below, along
with their application.
4. 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. Do not push anything through the honey-
comb; do not use compressed air to clear the pas-

Should you need to change a replaceable gasket, 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.
The procedure for replacing gaskets is the same,
regardless of the gasket location. Four easily-accom-
plished steps are involved:
Learn to Recognize —
and Avoid — Creosote
The EWF36A has been designed to reduce creosote
build-up significantly. However, regular chimney in-
spection 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.
1. Remove the existing fiberglass 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 gas-
ket.
3. Apply a thin bead of stove cement to the newly-
cleaned groove.
When wood is burned slowly, it produces tar, organic
vapors and moisture which 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” (3 mm) or more — it
should be removed to reduce the risk of a chimney fire.
4. Pack a new gasket into the groove. Wait until you
have placed all but a couple inches from the end
before you trim the end to an exact fit.
5. Place door back on fireplace, latch door and keep
closed for 1/2 hour to insure cement has set.
Replacing the Door Gaskets
Remove the door by lifting it straight up off its hinge
pins. Lay it face down on a padded surface.
If you do experience a chimney fire, act promptly to:
Follow steps 1-4 as described above.
•
Close the primary air control lever and the
damper
Get everyone out of the house.
Call the Fire Department.
Replace Damaged Door Glass Immediately
•
•
Do not operate the fireplace with damaged glass door.
Use the following procedure for glass replacement.
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 fireplace cool
completely. Remove the termination top. Then, using a
strong light, sight down into the chimney flue.
NOTE: Replace glass only with the replacement glass
made for this unit, available from your authorized
dealer.
• Remove the door and loosen the retaining clips which
hold the glass to the door frame. Remove clips. Use
caution when handling broken glass.
Clean the chimney using a specially designed brush the
same size and shape as the flue liner. Flexible fiber-
glass 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 on top of the fireplace.
• Examine the gasket that seals the glass to the door
frame. Replace if necessary with gasket obtained from
your local Vermont Castings’ Authorized Dealer. See
the directions for gasket replacement on Page 23.
If you can not do the chimney inspection yourself, con-
tact your local Vermont Castings’ Authorized Dealer, or
engage a professional chimney sweep to perform the
inspection and cleaning of the chimney.
• Check the flat surface of the door frame, and clear
away debris if necessary.
• Install the new glass.
• Secure the clips, being careful not to overtighten. Be
sure the glass is firmly seated against the gasket.
• Replace door.

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 product must be installed or serviced by a qualified installer,
preferably NFI or WETT (Canada) certified, as prescribed by the
local jurisdiction. It must be installed and operated at all times
in accordance with the Installation and Operating instructions
furnished with the product. Any alteration, willful abuse, accident, or
misuse of the product shall nullify this warranty.
2. This warranty is transferable; however, proof of original retail pur-
chase is required.
3. 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.
Any woodburning stove or part thereof that is repaired or replaced dur-
ing 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 misuse of the stove as described in
the Owner’s Guide, nor does it cover any 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.
Limited 1 Year Warranty
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.
5. This warranty does not cover a stove repaired by someone other
than a Vermont Castings Authorized Dealer.
6. 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.)
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. 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.
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. 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.
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.
9. CFM Corporation shall have no obligation to enhance or update any
unit once manufactured.
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.
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.
