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 CFM Corporation gas fireplace to
give off some odor the first time it is burned. This is due
to 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 (10) hours the first time you use it. If the op-
-
tional fan kit has been installed, place the fan switch in

Twist Lock Pipes
When using 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 sliding joints of any telescopic
vent section used in the system.
To join twist lock pipes together, simply align the beads
of the male end with the grooves of the female end,
twisting the pipe until the flange on the female end
contacts 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. (Fig. 18)
To make it easier to assembly 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
TWL100
Horizontal dimension from the outside face of the
wall to the center of the fireplace vent flange
The Vent Graph should be read in conjunction with the
following vent installation instructions to determine the
relationship between the vertical and horizontal dimensions fo 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. 19),
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 unit is 11’
(3.4m) the horizontal run to the face of the outer wall
must not exceed 14’ (4.3m).
EXAMPLE B:
If the vertical dimension from the floor of the unit is 7’
(2.1m), the horizontal run to the face of the outer wall
must not exceed 8¹⁄₂’ (2.6m).

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” (508mm). (Fig. 20, 21)
• Only one 45° elbow is allowed in these installations.
• Minimum clearances between vent pipe and combustible materials are as follows:
Locate and cut the vent opening in the wall.
For combustible walls first frame in opening. (Fig. 22)
NOTE: When using flex vent, the opening will have to
be measured according to the 1” (25mm) rise in 24”
(610mm) vertical run.
Combustible Walls:
x 240 mm) hole through the exterior wall and frame as
shown. (Fig. 22)
Noncombustible Walls: Hole opening should be 7¹⁄₂”
(191mm) 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. 23)
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. 21)
Cut a 10³⁄₈”H x 9³⁄₈” W (265 mm

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. 24) Attach the termination to the
wall as outlined in the instruction sheet supplied with
the termination.
