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
the “OFF” position during this time.

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 height and widths, refer to
Figures 4a, 4b and the Mantel Chart below.
The distances and reference points are not affected by
the fitting of a bay window front trim kit.
Noncombustible mantels and legs may be installed at
any height and width around the appliance. When using
paint or lacquer, it must be heat resistant to prevent
discoloration.
20012322

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. 17)
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. 18),
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’
(3.4 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’
(2.1m), 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. 19, 20)
• Only one 45° elbow is allowed in these installations.
• Minimum clearances between vent pipe and combustible materials are as follows:

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

FP1472
Fig. 25 There must be a 1/2” rise per foot length.
Vertical Sidewall Application
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, showing the relationship between ver
tical and horizontal side wall venting, will help to determine the various dimensions allowable.
Minimum clearance between vent pipes and combustible materials is one inch (25 mm) on top, bottom and sides unless otherwise noted.
When vent termination exits through foundations less
than 20” (508 mm) below siding outcrop, the vent pipe
must flush up with the siding.
It is 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 (or the top of
the Transition Elbow) to the face of the outer wall.
Horizontal plane means no vertical rise exists on this
portion of the vent assembly.
When installing the appliance as a rear
vent unit, the 90° or 45° Transition Elbow
attached directly to the rear of the unit is
NOT INCLUDED in the following criteria
and calculations, and unless specifically
mentioned should be ignored when calculating venting layouts.
• The maximum number of 90° elbows per side wall
installation is three (3). (Fig. 26)
• If a 90° elbow is fitted directly on top of the fireplace
flange the maximum horizontal vent run before the
termination or a vertical rise is 36” (914 mm). (Fig.
27)

• If a 90° elbow is used in the horizontal vent run
(level height maintained) the horizontal vent length
is reduced by 36” (914 mm). (Fig. 28, 29) This does
not apply if the 90° elbows are used to increase or
redirect a vertical rise. (Fig. 26)
Example: According to the vent graph (Page 14) the
maximum horizontal vent length in a system with a 7¹⁄₂’
(2.3 m) 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).

• The maximum number of 45° elbows permitted per
side wall installation is two (2). These elbows can be
installed in either the vertical or horizontal run.
• For each 45° elbow installed in the horizontal run,
the length of the horizontal run MUST be reduced by
18” (457 mm). This does not apply if the 45° elbows
are installed on the vertical part of the vent system.
• The maximum number of elbow degrees in a system

Step 1
Locate vent opening on the wall. It may be necessary
to first position the fireplace and measure to obtain hole
location. Depending on whether the wall is combustible
or noncombustible, cut opening to size. (Fig. 31) (For
combustible walls first frame in opening.)
NOTE: When using flex vent, the opening will have to
be measured according to the 1/2” (13 mm) rise in 12”
(305 mm) vent run.
Combustible Walls: Cut a 9³⁄₈”H x 9³⁄₈”W (240 mm x
240 mm) hole through the exterior wall and frame as
shown. (Fig. 31)

Measure wall thickness and cut zero clearance sleeve
parts to proper length (MAXIMUM 12” / 305 mm).
Assemble sleeve and attach to firestop with #8 sheet
metal screws (supplied). Install firestop assembly. (Fig.
32)
Zero clearance sleeve is only required for
combustible walls.
Step 3
Place fireplace into position. Measure the vertical height
(X) required from the base of the flue collars to the center of the wall opening. (Fig. 33)
Fig. 33 Vertical height requirements.
Step 4
Apply a band of silicone to the inner and outer flue
collars of the fireplace and using appropriate length of
pipe section(s) attach to fireplace with three (3) screws.
Follow with the installation of the inner and outer elbow,
again secure joints with three (3) sheet metal screws.
Wipe off any excess high temperature sealant.
Step 5
Measure the horizontal length requirement including a
2” (51mm) overlap, i.e. from the elbow to the outside
wall face plus 2” (51mm) (or the distance required if
installing a second 90° elbow). (Fig. 34)
Always install horizontal venting on a level
plane.
Step 6
Use appropriate length of pipe sections - telescopic or
fixed - and install. The sections which go through the
wall are packaged with the starter kit, and can be cut to
suit if necessary.
Sealing vent pipe and firestop gaps with high temperature sealant will restrict cold air being drawn in
around fireplace.

7” collard into their respective vent pipes. Double check
that the vent pipes overlap the collars by 2” (51 mm).
Secure the termination to the wall with screws provided
and caulk around the wall plate to weatherproof. As an
alternative to screwing the termination directly to the
wall, you may also use expanding plugs or an approved
exterior construction adhesive. You may also attach the
termination with screws through the inner body into the
4” vent pipe, however for this method, you must extend
the 4” pipe approximately 6” (152 mm) beyond the outer
face of the wall.
Support horizontal pipes every 36”
(914 mm) with metal pipe straps.

first spring 6³⁄₄” (172 mm) from the flex pipe end to the
unit.
Step 5
Slide the 7” (178 mm) flex vent pipe over the 4” flex
vent pipe and secure the 7” collar as described on Page
13.
Step 6
Bend the flex pipe horizontal so the bottom of the horizontal pipe measure 6¹⁄₂” (165 mm) from the top of the
unit immediately after the 90° formation. (Fig. 36) Be
sure to follow the 1/2” (13 mm) rise in a 12” (305 mm)
horizontal run rule.
Step 7
Install the 4” flex then 7” flex to the termination.
NOTE: The 40” (1016 mm) flex vent is used for 90° off
the top of the unit then out the back wall.
Follow Step 1 and 2 on Page 18.
Step 3
Install the four (4) spacer springs on the 4” flex vent
pipe. When installing the spacer springs around the 4”
pipe, stretch the spring to approximately 15” (381 mm),
wrap the spring around the pipe and interlock the ends
of the spacer spring approximately 2” (51 mm). Measure 6³⁄₄” (172 mm) from the end of the pipe. Place the
next spring 5” (127 mm) from the previously installed
spring. Place the next spring 6” (152 mm) from the last
spring. Finally place the last spring 12” (305 mm) from
the last spring installed. (Fig. 35)

Below Grade Installation
When it is not possible to meet the required vent terminal clearances of 12” (305 mm) above grade level, a
snorkel kit is recommended. It allows installation depth
down to 7” (178 mm) below grade level. The 7” (178
mm) is measured from the center of the horizontal vent
pipe as it penetrates through the wall.
Ensure the sidewall venting clearances are observed. If venting system is installed below ground,
we recommend a window well with adequate and
proper drainage to be installed around the termination area.
If installing a snorkel, a minimum 24” (610 mm) vertical
rise is necessary. The maximum horizontal run with the
24” vertical pipe is 36” (914 mm). This measurement
is taken from the collar of the fireplace (or transition

Vertical Through-the-Roof Application
This gas fireplace has been approved for:
• Vertical installations up to 40’ (12 m) in height. Up
to a 10’ (3 m) horizontal vent run can be installed
within the vent system using a maximum of two 90°
elbows. (Fig. 39)
• Up to two 45° elbows may be used within the horizontal run. For each 45° elbow used on the horizontal plane, the maximum horizontal length must be
reduced by 18” (450 mm).
Example: Maximum horizontal length:
No elbows = 10’ (3 m)
1 x 45° elbow = 8.5’ (2.6 m)
2 x 45° elbows = 7’ (2.1 m)
• A minimum of an 8’ (2.5 m) vertical rise is required.
• Two sets of 45° elbow offsets may be used within the
vertical sections. From 0 to a maximum of 8’ (2.5 m)
of vent pipe can be used between elbows. (Fig. 40)
• 7DVCS supports offsets. (Fig. 42) This application
will require that you first determine the roof pitch
and use the appropriate starter kit. (Refer to Venting
Components List)
• The maximum angular variation allowed in the system is 270°. (Fig. 40)
• The minimum height of the vent above the highest
point of penetration through the roof is 2’ (610 mm).

Inspecting the Venting System
This appliance venting system is designed and constructed to develop a positive flow adequate to remove
flue gases to the outside atmosphere.
Any foreign objects in the venting system, except those
designed specifically for the venting system, may cause
spillage of flue gases.
To inspect the venting system, make sure the main gas
valve is off. Remove window frame assembly (Refer to
Window Frame Assembly Removal Section). Using a
flashlight, check the area above the baffle in the com
bustion dome. Clean if necessary.
