IMPORTANT:
PLEASE REVIEW THE FOLLOWING CAREFULLY
Remove any plastic from from parts before turning the fireplace ON.
It is normal for fireplaces fabricated of steel to give off some
expansion and/or contraction noises during the start up or cool
down cycle. Similar noises are found with your furnace heat
exchanger or car engine.
It is not unusual for your gas fireplace to give off some odor
the first time it is burned. This is due to the curing of the paint
and any undetected oil from the manufacturing process.
Please ensure that your room is well ventilated-open all
windows.
It is recommended that you burn your fireplace for at least ten
four (4) hours the first time you use it. If the optional fan kit
has been installed, place the fan switch in the “OFF” position
during this time.

aesthetic purposes. We recommend a noncombustible
hearth which projects out 12” (305mm) or more from the
front of the fireplace.
Cold climate installation recommendation:
When installing this unit against a
non-insulated exterior wall or chase,
it is mandatory that the outer walls
be insulated to conform to applicable
insulation codes.
NOTE: Never allow vapor barrier to contact the
outer casing of this fireplace or venting.
Framing and Finishing
1. Choose the unit location.
2. Place the unit into position and secure it to the floor
with 1¹⁄₂” (38mm) screws, or nails. The holes to
secure the unit to the floor are located just behind
the access door grille on the left and right side of the
unit.
3. Frame in the fireplace with a header across the top.
It is important to allow for the finished wall face when
setting the depth of the frame.
4. Attach the fireplace to the frame using the adjust
able frame drywall strips (located behind the access
door for shipping). Preset the depth to suit the facing
material of the wall. The strips are adjustable to 1/2”
(13 mm), 5/8” (16 mm) or 3/4” (19 mm). (Fig. 4)
5. Screw through the slotted holes in the drywall strip
and into the pre-drilled holes in the fireplace side.
Measure from the face of the fireplace to the face of
the drywall strip to confirm the final depth.

Gas Line Installation
When purging gas line, the front window
frame assembly must be removed.
1. The gas pipeline can be brought in through the rear
of the fireplace as well as the bottom. Knockouts are
provided on the bottom behind the valve to allow for
the gas pipe installation and testing of any gas connection. It is most convenient to bring the gas line in
from the rear right side of the valve as this allows fan
installation or removal without disconnecting the gas
line.
The gas line connection can be made with prop
erly tinned 3/8” copper tubing, 3/8” rigid pipe or an
approved flex connector. Since some municipalities have additional local codes, it is always best to
con- sult your local authority and the National Fuel
Gas Code, ANSI Z223.1/NFPA 54 in the USA or the
CSA-B149.1 installation codes.
*Adhere to the following installation requirements in the State
of Massachusetts:
• The installer must be a licensed plumber or gas fitter.
• Flex connectors must be Massachusetts approved, cannot
exceed 36” (914 mm) in length, must be a minimum 1/2”
dia. and may not penetrate a wall.
1/2” Gas Supply
1/2” NPT X 3/8” Flare Shut-off Valve
-
5. For natural gas, a minimum of 3/8” iron pipe with a
gas supply pressure of 4.5” w.c. (from the gas meter). Consult with local gas utility and ANSI Z223.1/
NFPA 54 if any questions arise concerning pipe
sizes.
6. Turn the gas supply to ‘ON’ and check for leaks. DO
NOT USE OPEN FLAME FOR THIS PURPOSE.
Use an approved leak testing solution.
7. The appliance and its appliance main gas valve
must be disconnected from the gas supply piping
system during any pressure testing of that system at
test pressures in excess of 1/2 psig (3.5K Pa).
8. This appliance must be isolated from the gas supply
piping system by closing its equipment shut off valve
during any pressure testing of the gas supply piping
system at test pressures equal to 1/2 psig (3.5K Pa).
Always check for gas leaks with a mild
soap and water solution. Do not use an
open flame for leak testing.
When using copper or flex connector use only approved
fittings. Always provide a union when using black iron
pipe so that the gas line can be easily disconnected
for burner or fan servicing . See gas specifications for
pressure details and ratings.
The fireplace valve must not be subjected to any test
pressures exceeding 1/2 psi. Isolate or disconnect this
or any other gas appliance control from the gas line
when pressure testing.

(from valve)
FP297A
Fig. 5 Typical gas supply installation.
2. The gas control inlet is 3/8” NPT. typical installation
layout for rigid pipe is shown in Figure 8.
NOTE: All models are equipped with a flex tube
with a shut off valve having a 1/2” NPT inlet. The
flex line with shut off is shipped in the control
valve compartment. Using two wrenches, tighten the flexible tube at the shut off valve and at
the gas control
3. When using a flex connector,* use only approved
fittings. When a union is installed, provide easy
access in its placement for servicing. Refer to gas
specification for pressure details and ratings.
4. When a vertical section of gas pipe is required for
the installation, a condensation trap is needed. In
Canada see CSA-B149.1 for code details. See the
National Fuel Gas Code ANSI Z223.1/NFPA 54 in
the USA.
EB-1 Electrical Box
The fireplace, when installed, must be
electrically connected and grounded in
accordance with local codes or, in the absence of local codes, with the current CSA
C22.1 Canadian Electrical Code.
For USA installations follow local codes
and the national electrical code ANSI/
NFPA No. 70.
It is strongly suggested that the wiring of
the EB-1 Electrical Junction Box be carried
out by a licensed electrician.
Ensure that the power to the supply line
has been disconnected before commencing this procedure.

plate and refit the EB-1 assembly to the unit with the
screw removed in step 1.
Your fireplace is approved to be vented either through
the side wall, or vertical through the roof.
• Only CFM Corporation venting components specifically approved and labelled for this fireplace
may be used.
• Venting terminals shall not be recessed into a wall or
siding.
• Horizontal venting which incorporates the twist lock
pipe must be installed on a level plane without an
inclining or declining slope.
• Horizontal venting which incorporates the use of flex
venting shall have an inclining slope from the unit of
1” (25 mm) per 24” (610 mm).
There must not be any obstruction such as bushes,
garden sheds, fences, decks or utility buildings within
24” from the front of the termination hood.
Do not locate termination hood where excessive snow
or ice build up may occur. Be sure to check vent termination area after snow falls, and clear to prevent accidental blockage of venting system. When using snow
blowers, make sure snow is not directed towards vent
termination area.

Twist Lock Pipes
When using CFM Corporation twist-lock pipe it is not
necessary to use sealant on the joints. The only areas
of the venting system that need to be sealed with high
temperature silicone sealant are the collars on the
fireplace and termination, and the sliding joint of any
telescopic vent section used in the system.
To join the twist lock pipes together, simply align the
beads of the male end with the grooves of the female
end, then while bringing the ends together, twist the
pipe until the flange on the female end contacts the
external flange on the male end. It is recommended that
you secure the joints with three (3) sheet metal screws,
however this is not mandatory with twist lock pipe.
To make it easier to assemble the joints we suggest
putting a lubricant (Vaseline or similar) on the male end
of the twist lock pipe prior to assembly.

How to Use the Vent Graph
The vent chart should be read in conjunction with the
following vent installation instructions to determine the
TWL100

the center of the fireplace vent flange
Sidewall vent graph showing the relationship between vertical
and horizontal dimensions for a Direct Vent flue system.
Fig. 10 Sidewall venting graph. (Dimensions in feet)
relationship of the vertical and horizontal dimensions of
the vent system.
1. Determine the height of the center of the horizontal
vent pipe exiting through the outer wall. Using this
dimension on the Sidewall Vent Graph (Fig. 10),
locate the point intersecting with the slanted graph
line.
2. From the point of this intersection, draw a vertical
line to the bottom of the graph.
3. Select the indicated dimension, and position the
fireplace in accordance with same.
Example A:
If the vertical dimension from the floor of the fireplace
is 11’ (3.4 m) the horizontal run to the face of the outer
wall must not exceed 14’ (4.3 m).
Example B:
If the vertical dimension from the floor of the unit is 7’
(2.14 m), the horizontal run to the face of the outer wall
must not exceed 8¹⁄₂’ (2.6 m).

Rear Wall Vent Application
When installed as a rear vent unit this appliance may be
vented directly to a termination located on the rear wall
behind the appliance.
• Only CFM Corporation venting components are
approved to be used in these applications (See
‘Venting Components’ listed for different installation
requirements).
• The maximum horizontal distance between the rear
of the appliance (or end of the transition elbow in a
corner application) and the outside face of the rear
wall is 20” (508 mm). (Fig. 11, 12)
• Only one 45° elbow is allowed in these installations.
• Minimum clearances between vent pipe and com-
bustible materials are as follows:
Top - 2” (51 mm)
Sides - 1” (25 mm)
Bottom - 1” (25 mm)

Step 1
Locate and cut the vent opening in the wall. For combustible walls first frame in opening. (Fig. 13)
NOTE: When using flex vent, the opening will have to
be measured according to the 1/2” (13 mm) rise in 12”
(305mm) vertical run.
Combustible Walls:
Cut a 10³⁄₈”H x 9³⁄₈” W (265 x 240
mm) hole through the exterior wall and frame as shown.
(Fig. 13)
Noncombustible Walls:
Hole opening should be 7¹⁄₂”
(191 mm) diameter.
Zero clearance sleeve is only required for
combustible walls.
Step 2
Measure wall thickness and cut zero clearance sleeve
parts to proper length (Maximum 12” / 305 mm). Assemble sleeve to its maximum opening (10³⁄₈” x 9³₈”)
and attach to firestop assembly. (Fig. 14)
Step 3
Measure the horizontal length requirement for the venting including a 2” (51 mm) overlap, i.e. from the elbow
to the outside wall face plus 2” (51 mm). (Fig. 12)

Step 4
Install the 4” (102 mm) vent to the appliance collar and
secure with 3 sheet metal screws. Install the 7” (178
mm) vent pipe to the appliance collar and secure with 3
sheet metal screws. It is not necessary to seal this connection. If a 45° elbow is being used attach the elbow
to the appliance in the same manner then attach the
venting to the elbow.
It is critical that there is no downward
slope away from the appliance when connecting the vent or elbow.
Step 5
Guide the venting through the vent hole as you place
the appliance in its installed position. Guide the 4” (102
mm) and 7” (178 mm) collar of the vent termination into
the outer ends of the venting. Do not force the termination. If the vent pipes do not align with the termination,
remove and realign the venting at the appliance flue
collars. (Fig. 15) Attach the termination to the wall as
outlined in the instruction sheet supplied with the termination.

Follow Steps 1 and 2 on Page 13.
Step 3
Install the 4” (102 mm) flex vent pipe to the appliance
collars described in “General Information Assembling
Vent Pipes”, Page 10. If the installation requires a 45°
angle, grasp the vent pipe close to the appliance collar
and bend to 45°. DO NOT exceed 45°. (Fig. 16)
Install the 7” vent pipe in the same manner as Step 2.
Termination
Flex Section
Appliance Collars
Since it is very important that the venting system maintain its balance between
the combustion air intake and the flue
gas exhaust, certain limitations as to vent
configurations apply and must be strictly
adhered to.
The Vent Graph shows the relationship between vertical and horizontal side wall venting and will help to
determine the various dimensions allowable.
Minimum clearance between vent pipes
and combustible materials is 1”(25mm) on
top, bottom and sides unless otherwise
noted.
When vent termination exits through foundations less
than 20” below siding outcrop, the vent pipe must
flush up with the siding. It is always best to locate the
fireplace in such a way that minimizes the number of
offsets and horizontal vent length.
The horizontal vent run refers to the total length of vent
pipe from the flue collar of the fireplace to the face of
the outer wall.
Horizontal plane means no vertical rise exists on this
portion of the vent assembly.
FP1473
Fig. 16 Grasp the vent pipe close to the collar and bend to
45° angle. Do not exceed 45°.
NOTE: There must be a 1/2” (13 mm) rise in a 12” (305
mm) length of flex vent. (Minimum 1” (25 mm) rise.)
Step 4
Assemble the flex vent to the collars on the termination
as you did on the appliance.

• The maximum horizontal vent run is 20 ft. (6.1 m)
when the vertical vent rise is 7¹⁄₂ ft. (2.3 m). (Fig. 18)
• The maximum number of 90° elbows per side wall
installation is three (3).
• If a 90° elbow is used in the horizontal vent run
(level height maintained) the maximum horizontal
vent length is reduced by 36” (914 mm). (Fig. 19)
This does not apply if the 90° elbows are used to
increase or redirect a vertical rise. (Fig. 20)
Example: According to the chart the maximum
horizontal vent length in a system with a 7.5’ (2.3
m) vertical rise is 20’ (6 m) and if a 90° elbow is
required in the horizontal vent it must be reduced to
17’ (5.2 m). In Figure 19 Dimension A plus B must
not be greater than 17’ (5.2 m).
