-
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 pipeline can be brought in through the rear
of the appliance 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.

Fig. 7 Remote switch wiring diagram for R models.
Alternate Switch Location
The remote switch can be installed on the front/side
of the access door. Simply mount the switch to the
bracket provided and screw the bracket to either side
of the frame, lining up the screws with the pre-punched
holes. (Fig. 8)
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 form the gas line when
pressure testing.
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
when pressure testing.
Remote ON/OFF Switch
Do not wire the remote ON/OFF wall switch for this gas
appliance into a 120v power supply.
1. Thread wire through the electrical knockout located
on either side of the unit. Take care not to cut the
wire or insulation on metal edges. Ensure the wire is
secured and protected form possible damage. Run
one end of the gas control valve and the other end to
the conveniently located wall switch.

Fig. 8 Alternate switch location.
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.

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. 20)
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).

Install the 4” (102 mm) vent to the appliance collar and
secure with three (3) sheet metal screws. Install the 7”
(178 mm) vent pipe tot he appliance collar and secure
with three (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 there is no downward slope
away from the appliance when connecting
the vent or elbow.
STEP 5
Guide the venting through the vent hole a 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 reali
gn the venting at the appliance flue collars.

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. 26 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.
Step 4
Assemble the flex vent to the collars on the termination
as you did on the appliance.

• 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. 29)
This does not apply if the 90° elbows are used to
increase or redirect a vertical rise. (Fig. 30, 31)
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’
(5.2 m). In Figure 31 Dimension A plus B must not be
greater than 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” (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
is 270°. (Fig. 32)
