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.

The gas control is equipped with a captured screw type
pressure test point, therefore it is not necessary to provide a 1/8” test point up stream of the control.
When using copper or flex connector use only approved
fittings. Always provide a union when using black iron
pipe so the gas line can be easily disconnected for
burner or fan servicing. See gas specification for pressure details and ratings.
The fireplace valve must not be subjected to any test
pressures exceeding 1/2 psi. Isolate or disconnect this
and any other gas appliance control from the gas line

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.
