also applies to the distance between the mantel leg (if
fitted) and the fireplace.
For the correct mounting height and widths refer to
Figs. 3a and 3b, and the following Mantel Charts.
The fitting of a bay window trim kit does not effect
the distances and reference points referred to in the

Gas Line Installation Remote ON/OFF Switch
When purging the gas lines, the front window frame assembly must be removed.
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.
The gas line connection can be made with properly
tinned 3/8” copper tubing, 3/8” rigid pipe or an approved flex connector. Since some municipalities have
additional local codes, it is always best to consult your
local authority and the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 in the USA or the CSA-B149.1 installation code.

Always check for gas leaks with a mild
soap and water solution. Do not use an
open flame for leak 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.

Canadian Installations:
Venting system must be installed in accordance with the
current CSA-B149.1 installation code.
USA Installations:
General Information Assembling Vent Pipes
* Be sure the vent is actually crushed before proceeding. Apply a tug to be sure the vent will not slip off the
collars.
Repeat process with 7” flex vent pipe. The same procedure must be performed on the vent side.
The venting system must conform with local codes and/
or the current National Fuel Gas code ANSI Z223.1/
NFPA 54.
Only venting components manufactured by CFM Corporation can be used in Direct Vent systems.
Flex Vent Pipes
Before joining the flex vent pipe to the unit, apply a
bead of high temperature sealant* (provided) to the 4”
pipe exiting the fireplace. Secure flex vent piep in place
with a hose clamp (provided).
*Be sure the flex pipe overlaps at least 1” (25mm) onto
the collars of the fireplace and termination. If the ter
mination has an internal bead, be sure to overlap and
secure 1” (25mm) past the bead.

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 collars on the
fireplace and termination, and the sliding joint 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.

How to Use the Vent Graph
The vent chart should be read in conjunction with the
following vent installation instructions to determine the
relationship of the vertical and horizontal dimensions of
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. 13)
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 11ʼ (3.4m) the horizontal run to the face
of the outer wall must not exceed 14ʼ (4.3m).
Example B:
If the vertical dimension from the floor of the unit is
7ʼ (2.14m), the horizontal run to the face of the outer
wall must not exceed 8¹⁄₂ʼ (2.6m).

Rear Wall Venting Applications
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. (Refer to
“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. 14)
• Only one 45° elbow is allowed in these installations.
• Minimum clearances between vent pipe and com-
bustible materials are as follows:
Top - 2” (50mm)
Sides - 1” (25mm)
Bottom - 1” (25mm)
