This appliance may be installed in an aftermarket permanently located, manufactured home or mobile home,
where not prohibited by local codes.
This appliance is only for use with the type of gas indicated on the rating plate. This appliance is not convertible
for use with other gases, unless a certified kit is used.
IMPORTANT:
PLEASE REVIEW THE FOLLOWING CAREFULLY
Remove any plastic from trim 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 (10) 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.

Your fireplace is approved to be vented either through
the side wall, or vertically through the roof.
• Only CFM Corporation venting components specifi-
cally approved and labelled for this fireplace may be
used.
• If vent termination is installed in an accessible loca-
tion, Vent Termination Guard #53525 shall be installed.
• Vent terminations 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
1/2” (13 mm) per 12” (305 mm).
There must not be any obstruction such as bushes,
garden sheds, fences, decks or utility buildings within
24” (610 mm) 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.
Location of Vent Termination
It is imperative the vent termination be located observing the minimum clearances as shown on the next
page.

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 sliding joints 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 pipe 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.

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 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).

Vertical Sidewall Applications
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”(25 mm) 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.
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.
FP1473
Fig. 24 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”

Step 4
Assemble the flex vent to the collars on the termination
as you did on the appliance.

This does not apply if the 90° elbows are used to
increase or redirect a vertical rise. (Fig. 28, 29)
Example: According to the vent graph (Page 15) 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’

• 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” (45 cm). 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 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 silicone.
STEP 5
Measure the horizontal length requirement including a
2” (51 mm) overlap, i.e. from the elbow to the outside
wall finish plus 2”, or the distance required if installing a
second 90° elbow. (Fig. 24)
Always install horizontal venting on a level
plane.
STEP 6
Use appropriate length of pipe section - 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

Below Grade Installations
When it is not possible to meet the required vent terminal clearances of 12” (305 mm) above grade level
a snorkel kit is recommended. This allows installation
depth of down to 7” (178 mm) below grade level. The
7” 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.
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
elbow) to the face of the exterior wall. See the Sidewall
Venting Graph for extended horizontal run if the vertical
exceeds 24” (610 mm).
1. Establish vent hole through the wall. (Fig. 31)
2. Remove soil to a depth of approximately 16”
(406 mm) below base of snorkel. Install window
well (not supplied). Refill hole with 12” (305 mm) of
coarse gravel leaving a clearance of approximately
4” (102 mm) below snorkel. (Fig. 37)
3. Install vent system. See Page 18, Steps 2 through 5.
4. Ensure a watertight seal is made around the vent
pipe coming through the wall.
5. Apply high temperature sealant caulking (supplied)
around the 4” and 7” snorkel collars.
6. Slide the snorkel into the vent pipe and secure to the
wall.
7. Level the soil to maintain a 4” (102 mm) clearance
below snorkel. (Fig. 37)

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. 40)
• Up to two 45° elbows may be used within the hori-
zontal 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’ (2.5m) 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 sys-
tem 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 combustion dome. Clean if necessary.
Fig. 64 Flame adjustment knob for SIT valve.
The Manual ON/OFF valve was designed particularly
for the main burner operation. The main burner flame
can be turned on and off as desired. This valve is recommended to be set to the “ON” position when lighting
the unit. (Fig. 65)

4. Sequence is failure code followed by light not blink
-
ing for 30 seconds.
5. In the event of multiple failure codes, next failure
code follows previous failure code by approximately
3 seconds.
If an Error Code 3 is observed while performing the
testing, complete the following:
1. Make sure the spade connectors are pushed all the
way on. If the Error Code 3 is still showing, then go
to the next step.
2. Switch the front two thermopile leads with the back
two. Be sure the white lead is connected to the
spade with the white dot next to it. If the Error Code
3 is still showing, replace the thermopiles.
If an Error Code 8 is observed while performing the
testing, complete the following:
1. Confirm the valve is not in REMOTE mode.
• If the valve is producing Error Code 8 and in RE-
MOTE mode, the valve is defective and should be
replaced.
• If the valve is in LOCAL mode and producing Er-
ror Code 8, then go to the next step.
