Meet Your New Woodburning Fireplace
Your new fireplace is a highly engineered system
designed to provide maximum pleasure with troublefree operation. It can only perform to its fullest potential
if you operate and care for it properly. This manual is
provided to help you do that.
The first things you should know are the basic parts
of your particular fireplace model and what each part
does. This will give you a better understanding of the
descriptions that follow in this manual. It is important
to note that all of these parts have been engineered
to work together. If you decide to use some unapproved part or make any modification, the fireplace
will not operate as it was engineered to and, therefore, may possibly cause a fire hazard.
CFM Corporation warranty will be voided by, and
CFM Corporation disclaims any responsibility for
the following actions:
• Installation of any damaged fireplace or chimney
component;
• Modification of the fireplace, chimney assembly
or any of the component parts thereof; (except
for chase flashings as detailed in CFM Corporation
Chimney Top installation instructions).
• Installation other than as instructed by
poration
CFM Cor-
or
• Installation and/or use of any component part not
manufactured or approved by
combination or assembly with a
fireplace system, notwithstanding any independent testing laboratory or other third party approval of such component parts or accessory.
Any of the above actions may possibly cause a fire
hazard.

WARNING
Risk of fire! Do not install a firescreen on
this prefabricated fireplace. A firescreen
will prevent proper ventilation and increase
the risk of a chimney fire.
NOTE: Remove the warranty card from the plastic bag in which you found this owner’s manual.
The warranty for your fireplace is located on the
back page of the installation instructions. Keep the
warranty in a safe place for future reference if you
should ever need service covered under this warranty. Fill out the warranty card and mail it to CFM
Corporation. In order to validate your warranty, it is
mandatory that you write the serialization number
(a series of letters and numbers located below the
model number) on the warranty card. The serial
number is stamped into the black plate attached to
the inner dome side of the firebox.
For better understanding of your fireplace, familiarize
yourself with the following parts and terminologies used
in this manual:
The firebox is the main cavity of the fireplace where
the fire is built. Its shape and size are designed to
promote efficient burning of the fire and to reflect the
maximum amount of heat through the fireplace opening
into the room.
The hearth is the floor of the firebox. It is made of a
refractory material and functions as a base for the fire
grate to rest on.
The chimney is the complete vertical structure that
houses the flue. With CFM Corporation fireplaces, the
chimney utilizes a special air-cooled design that keeps
the outside of the chimney from getting too hot.
The flue is the innermost passageway of the chimney
system through which the smoke and gases from the
fire travel to the out-of-doors.
The damper is the door to the flue that prevents loss
of heated room air from escaping up the flue when
the fireplace is not in use. The damper must be in the
open position whenever fire is burning so that smoke
and gases can escape up the flue rather than into the
room. It should not be closed until the fire is completely
out. The BR, BC, BCMH, TF, TL, CR, SR, ODSR, SC,
SHR, ODSHR, TSH, STR, TST, CVR and EWF Series
fireplace damper operates only in the full open or full
closed position. The control is located in the front firebox dome areas. (Figs. 1, 2, 3, 4 & 5)
The EWF damper is open to start or revive the fire and
closed, for normal operation and to control burn rate.
NOTE: Always open the damper before opening the
doors. Close damper to set burn rate.
The WMC Series fireplace damper is adjustable to help
provide a more efficient fireplace operation. Dampering
down the open flue further intensifies the firebox heat
exchanger temperature by reducing the loss of hot flue
gases. The adjustable damper control is located in the
center just below the top outlet grille. (Fig. 1) Refer to
Proper Operating Procedure on Page 4.

The firescreen is a protective curtain of wire mesh that
helps keep sparks and hot embers from leaving the
firebox. The firescreen should always be kept closed
whenever a fire is burning in the firebox.
Your fireplace may also include many of the following
energy efficient components that provide additional
heat output and efficient home operation:
Heat-Circulation adds to the standard radiant heat
output of a traditional fireplace by distributing useful
amounts of convective heat into the home. Heat-circulating fireplaces circulate cool room air around the hot
firebox where it is warmed and returned to the room as
beneficial heat. The BC, BCMH, TL, SC, WMC, BFC
and EWF Series fireplace models feature heat circulation.
The Heat Exchanger is a multiple wall construction
that directs room air around the firebox and back into
the room of a heat-circulating fireplace system. Heat
transfer from the hot fire to the circulating room air occurs through these passageways. The heat exchanger
is the heart of a heat-circulating system which provides
the extra room heat that is lost with conventional fireplaces.
The Air Inlet/Outlet Grilles are part of the heat-circulation system. Cool room air enters through the bottom
grille and/or lower side inlet grilles and travels through
the heat exchanger passageways. The resulting hot air
is then returned to the room through the upper outlet
grille.
NOTE: Air inlet/outlet grilles should never be covered or blocked off. The heat-circulation system
is also used as fireplace cooling system for safe
operation.
Outside Combustion Air: A fire requires a sufficient
amount of air in order to burn properly. Insufficient air
will cause smoking, sooting and harmful gases to filter
out of the fireplace into the room. As the fire burns in
the firebox, replacement air enters the firebox opening
from the room to make up the loss of combustion air.
Often tightly sealed and well insulated homes do not
provide sufficient amounts of air for this natural replacement process. To maintain a constant flow of combustion air, direct outside air may be needed.
CFM Corporation fireplaces are designed with outside
air capabilities which supply outside combustion air
directly to the firebox. The air system requires ducting
from fireplace to an outside air source at time of original
installation. The WMC, BR, BC, BCMH, TF, TL, CR, SC,
SHR, ODSHR, TSH, SR, ODSR, STR, TST and CVR
Series fireplaces offer this feature as standard equipment. The BFC fireplace includes integral outside air
and no additional ducting is necessary.
If your fireplace is equipped with outside air, the control
lever will be located at the front edge of the left side
brick on the BR, TF, SR, ODSR, WMC, STR and TST
Series. On the CR Series fireplaces, it is located at the
lower left or right corner of the air inlet. On the SHR,
ODSHR and TSH Series, the control lever is located in
the center, just above the left side brick. Refer to Page
6 for proper operation procedure.
Primary Air Control: On the EWF Series fireplace, the
primary air control regulates the amount of heat the fire
will produce and how long it will burn. The primary air
control is located in the upper left corner of the unit. It
is the primary source of air for starting, maintaining and
reviving the fire.
The air supply is open to the maximum when the control
lever is rotated clockwise on the EWF36A or pushed
down on the EWF30 and closed when rotated counterclockwise on the EWF36A or pushed up on the EWF30.
To vary the burn rate, adjust the control 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 can adjust to any
position you desire.
Glass Doors improve fireplace efficiency to help save
home energy. When firing a fireplace, the need for
combustion air draws room air into the firebox where it
mixes with the hot flue gases and then is expelled up
the open flue. The loss of preheated room air is most
significant when burning a low intensive fire which
normally occurs during start-up and shutdown of the
fireplace. CFM Corporation glass doors are specially
designed to reduce the amount of heated room air
loss and, at the same time, allow the proper amount
of combustion air to be filtered into the firebox for safe
operation.
When using glass doors on a heat-circulating fireplace,
the controlled combustion air also intensifies the heat
exchanger temperature and slows the fuel burning rate.
The result is maximum heating while using the least
amount of fuel. Glass doors are standard equipment on
WMC, BFC and EWF Series fireplaces and are offered
as optional accessories for all other CFM Corporation
fireplace models. Refer to proper operation procedures
on Page 6 and 7.
Forced Air Circulation: Heat-circulating fireplaces use
the natural process of hot air rising to distribute heat
from the fireplace to the room. This principle is sufficient for small room application. To distribute a constant
flow of warm air further into a larger room, forced air
fans are recommended. To determine if the fireplace is
equipped with fans, use a flashlight and look through
the lower inlet air grille. CFM Corporation offers optional
fan kits for all heat-circulating models. For easy installation of an optional fan kit, the fireplace should be wired

during its installation. Fans are standard equipment for
WMC and BFC units.
NOTE: CFM Corporation Forced Air Systems are
designed to distribute heat at a specific cfm rate.
Any attempt to increase air movement through the
heat exchanger will decrease the heat transfer time
which will result in cooler heat circulation temperatures.
Energy efficient options such as glass doors and fans
(Heat-circulating models) can easily be added after
your original fireplace installation. Refer to Page 11 for
description and proper model number.
How to Operate Your Fireplace
Your fireplace can provide countless hours of pleasure
and security. However, use your fireplace carefully
because any time you build a fire inside a house, a
problem may develop.
1. Open Flue Damper
The flue damper is meant to be closed only when the
fire is completely out and the fireplace is not in use.
This prevents the loss of room air up the open flue. Re
member, the damper must always be in the “fully open”
position when a fire is burning.
WMC Damper: The WMC Series fireplace flue damper
is “opened” and “closed” by a knob located just below
the top outlet grille. (Fig. 1) The damper is adjustable
and may be adjusted to a partially open position as
long as the glass doors are closed and smoke buildup
does not occur in the firebox. Most efficient operation is
obtained in the least open position. When refueling, fully
open damper before opening glass doors.
BR, BC, BCMH, TF, TL, CR, SR, ODSR and SC Se
ries Damper: The flue damper is located in the dome
area in the middle of the firebox. The damper is opened
by rotating the lever to the right. The damper is closed
by pushing the lever to the left and is locked closed by
the damper clip located on the dome. The damper is
not adjustable and must only be operated in the
fully open position. (Fig. 2)

STR, TST & CVR Series Damper: The flue damper
is located in the dome area in the middle of the firebox. The damper is opened by pushing the lever in an
upward direction. The damper is closed by pulling the
lever down toward the hearth brick at the bottom of the
fireplace. The damper is not adjustable and must
only be operated in the fully open position. (Fig. 3)
SHR, ODSHR & TSH Series Damper: The flue damp-
er is “opened” and “closed” by an actuator handle and
linkage located in the front of the combustion dome of
the fireplace. The damper is not adjustable and must
be operated in the fully open position. (Figs. 4 & 5)
EWF Series Damper: The flue damper control is locat-
ed in the upper right corner of the fireplace. The damper
is open when the lever is rotated clockwise and pulled
out on the EWF36A and pulled out on the EWF30.
Open the damper to start or revive a fire. The damper is
closed when pushed in. For the EWF36A only, when the
damper is in the open position, with the lever pulled out,
and rotated in the fully clockwise direction, the handle
can ‘telescope’ back without closing the damper or any
damper movement. There are no intermediate settings
for the damper.

2. Building the Fire
To build a fire, a basket grate should be used to raise
the fuel off the hearth. Combustion air needs to flow up
through the fuel for proper burning. Most CFM Corporation fireplaces come equipped with a basket grate.
A specially designed basket grate is required for your
fireplace. When replacing the basket grate, a specific
model must be used. Refer to Page 11 for the model
number.
The EWF does not use a basket type grate. Build the
fire directly on the grate. Do not elevate the wood.
Place a generous amount of crumpled or twisted newspaper under the grate on the hearth. Allow a few ends
of the paper to extend out beyond the log area for later
lighting. Arrange kindling (small diameter sticks) in a
crisscross pattern on top of the paper.
Place a large diameter log, preferably one that has
been split, across the grate within approximately 1/2” of
the back wall of the fireplace. Place a second split log
1” to 2” in front of the first log. Place a third split log on
top of the other two, forming a crude pyramid. Be sure
the irregularities of the logs form air spaces between
the logs. (Fig. 6) If they do not, place a few sticks of
kindling between the logs to separate them slightly.
Additional logs may be added as needed to maintain
heat output. Logs should be split preferably in quarter
sections or smaller pieces. Split logs have more burning surfaces than whole logs and burn more readily.
The type and condition of wood that you use to build
your fire will have a great effect on the heat output of
your fireplace. For best results use oak, maple, birch,
hickory, apple or similar hardwoods. The wood should
be dry and seasoned 9 months to a year before use.

Soft woods, are not as desirable as hardwoods because they burn quickly and can cause resin build up
in the flue. Wet or green wood smolders and often
smokes.
The use of artificial logs of any type has
been found to create smoking and sooting
problems. These types of materials have
also been found to increase the danger
of fire. For these reasons the use of any
type of artificial log is prohibited in any of
our products. The use of any artificial logs
will void any warranty associated with our
products.
Caution: Do not burn scrap lumber, pine branches,
trash, plastic, flame colorants, soot cleaners or
other chemicals or compounds.
3. Starting the Fire
Before starting the fire, make sure the damper is in the
fully open position.
Lay a sheet of newspaper on top of the logs and set it
afire. This warms the chimney, improving the flow of hot
air from the fire when it is started.
When warm-up newspaper is partially burned, ignite
the starter paper under the kindling. Close the fireplace
screens as soon as you have completed this step.
When firing a new fireplace, you may smell a slight odor
and see smoke coming from the fireplace or the heatcirculating outlet grilles. This is the paint curing and oil
burning off the metal. This is normal and will disappear
after the first few fires. If your fireplace is equipped with
glass doors and outside air, open the doors and close
the outside air. The odors and smoke will be drawn into
the firebox and expelled up the flue.
NOTE: Never use gasoline, gasoline type lantern
fuel, kerosene, charcoal lighter fluid or similar
liquids to start or ‘freshen up’ a fire in this fireplace
while it is in use.
4. Open Outside Air Damper
Your fireplace may be equipped with outside combustion air. To determine, refer to “Outside Combustion Air”
on Page 3.
If your fireplace has outside air, the air damper should
be ‘closed’ prior to starting fire. Start the fire and allow
the firebox to preheat 5-10 minutes, then ‘open’ the
air damper. The heat from the hot firebox will draw the
outside air in more effectively.
CR Air Damper. To ‘open’, push control rod to right
and pull out. To ‘close’, push control lever away from
the front face until it stops. Damper is spring-loaded and
will hold closed.
BR, BC, BCMH, TF, TL, SR, ODSR, SC, STR, TST,
CVR, WMC Series Air Damper. To ‘open’, push the
control lever down toward the hearth brick. To ‘close’,
pull the control lever up and over. (Fig. 7)
SHR, ODSHR, TSH Air Damper. To ‘open’, push con
trol lever up and back. To ‘close’, pull lever forward and
down. (Fig. 8)
NOTE: To ‘open’ or ‘close’ damper during firing,
use a long metal probe such as a fireplace poker
to operate lever. Do not use your hand as control
lever is hot.

5. Primary Air Control
The EWF has a single air control that regulates the
amount of heat the fire will produce and how long it will
burn.
The Primary Air Control is located in the upper left cor
ner of the unit. It is the primary source of air for starting,
maintaining and reviving the fire.
Generally, more air entering the fireplace makes the fire
burn hotter and faster, while less air prolongs the burn.
The air supply is open to the maximum when the control
lever is rotated clockwise on the EWF36A or pushed
down on the EWF30 and closed when rotated counterclockwise on the EWF36Aor pushed up on the EWF30.

position you desire.
6. Operating Glass Door
WARNING: Use only glass doors approved by CFM
Corporation for use with your particular fireplace.
If your fireplace is equipped with glass doors, start the
fire and leave the doors fully open. AFTER the fire is
well started, then the doors may be closed. We recommend for the most efficient use of glass doors on
all models of CFM Corporation fireplaces, except for
models BFC, EWF and WMC Series, that doors must
be fully open when firing at a ‘moderate’ to ‘hot’ rate.
Firing at a ‘low’ to ‘moderate’ rate or allowing fire to die
out, doors should be closed. The BFC, EWF and WMC
Series fireplaces are designed for maximum heat output with doors fully closed at all times.
NOTE: The BFC fireplace should be operated only with
the doors fully closed.
NOTE: The EWF fireplace should be operated only
with the doors fully closed or fully open only when the
optional spark screen is installed.
WARNING: FIREPLACES EQUIPPED WITH DOORS
SHOULD BE OPERATED WITH DOORS FULLY
OPEN OR DOORS FULLY CLOSED. IF DOORS ARE
LEFT PARTLY OPEN, GAS AND FLAME MAY BE
DRAWN OUT OF THE FIREPLACE OPENING CRE
ATING RISKS OF BOTH FIRE AND SMOKE. Refer to
Figure 9 for correct door positions.
Do not close the glass doors on an excessively hot fire.
This could remove the temper from the glass, causing
it to crack into small pieces. The glass must be allowed
to warm slowly. The tempered glass in the doors will
withstand a gradual temperature rise to 550° F, which
is more than a normal fire will create. An excessively
hot fire can be created by such things as pitch laden
logs, very dry mill end lumber or large amounts of paper
or cardboard cartons. Keep the fire well back from the
doors and never let flames contact the glass.
Breakage may occur if the glass doors are mishandled.
Always use caution when operating the doors and do
not slam or force them into position.
MD706-7
Fig. 9 Top view of glass door operation.
8 20000706
Please note that under moderate firing, some discoloration may occur on brass door frames. Keeping the fire
small and toward the back of the fireplace will prevent
this discoloration.
7. Operating Fan
If your fireplace is heat-circulating with a fan option,
build the fire in the normal manner with the fan(s) ‘
OFF’.
Preheat your firebox and heat exchanger system for 20
- 30 minutes. After a good fire has developed, turn the
fan switch to the ‘ON’ position and heated air will immediately flow from the grille.
8. Tending the Fire
The heat output of a fireplace depends on how well
you build and tend the fire. A well-tended fire assures a
constant heat output. Keep the fire burning at a con
stant level by adding additional logs as necessary. Use
a poker to push the burning logs together into a tight
group at the back of the fireplace each time you add
new logs. Keep the bed of hot ashes located directly
under the logs. This aids in maintaining the fire, but do
not let the ashes get so deep that they interfere with
adequate air flow up through the logs.
Except when adding logs to the fire, the firescreen
should always be kept closed whenever there is a fire
burning in the firebox.
9. At the End of the Day
If your fire has not burned itself out by bedtime, you
may wish to use your tongs to stand any burning logs
on end in the corners of the firebox. In this position,
they usually will quickly burn out and will provide good
base for your next fire. Be sure the firescreen or glass
doors are kept closed and the damper kept open until
the fire is completely out.
10. Disposal of Ashes
Clean the ashes from the firebox before starting each
fire. Ashes should be placed in a metal container with
a tight fitting lid. The closed container of ashes should
be placed on a noncombustible floor or on the ground,
well away from all combustible material, pending final
disposal. If the ashes are disposed of by burial in soil
or otherwise locally dispersed, they should be retained
in the closed container until all cinders have thoroughly
cooled.
Leave only enough ashes to insulate the cold hearth so
the fire will start faster. Excessive ash levels will slow
the burning of your fire and cause your grate to burn out
quickly.
11. Operation of BFC36, Clean-Burning Fireplace
The BFC36 fireplaces have been designed specifically
to reduce smoke and hydrocarbon emissions; however,
the performance of these fireplaces depends on proper
operation. In order to reduce emissions use only well
seasoned firewood. Avoid slow burning smoldering
fires and maintain a hot coal bed on which to place new
wood.
High firebox temeratures help to ensure effective opera
tion of these clean-burning models.
The BFC36 clean-burning fireplaces must be burned
with the cabinet doors fully closed in order to reduce
emissions. Any modifications to the internal components of these fireplaces will likely cause an increase in
emissions. Always use the correct model grate and do
not remove any brick components, baffles or hardware
from the firebox.
12. Operation of EWF36A fireplace.
The EWF36A meets the US Environmental Protection
Agency’s emission limts for wood heaters sold after
July 1, 1990.
The catalytic combustion system in your EWF produces
the best conditions for secondary combustion.
When the stove damper is closed, smoke goes through
the catalytic element, burning at temperatures of
500-600°F (260-315°C), half the temperature normally
needed for unaided secondary combustion.
The catalytic element is a ceramic “honeycomb” coated
with a noble metal, usually platinum. The element is in
the secondary combustion chamber, made of a special high-temperature insulating refractory material.
The chamber provides the correct environment necessary for secondary combustion of the fuel (smoke).
Closing the damper may also reduce draft. Closing
the damper too soon may put out the fire or deactivate
the combustor. Close the damper only when the fire is
well established. When starting a fire, wait until there is
an ember bed of at least 3-4 inches before closing the
damper.
13. Operation of EWF30
The EWF30 meets the US Environmental Protection
Agency’s emission limits for wood heaters sold after
July 1, 1990.
The non-catalytic combustion system produces the
proper conditions for secondary combustion.
When the damper is closed, smoke goes through the
refractory combustion chamber at the back of the until.
Inside this chamber is where the secondary combustion
occurs.
Like the EWF36A, closing the damper too quickly is
detrimental to secondary combustion. When starting a
fire, wait until there is an ember bed of at least 3” - 4”
(76-102 mm) before closing the damper.
