ON.
It is normal for fireplaces fabricated of steel to give off some
expansionand/orcontractionnoisesduringthestartuporcool
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.
6. Control compartments, burners and air passages in this
fireplace should be kept clean and free of dust and lint.
Make sure the gas valve and pilot light are turned off before
you attempt to clean this fireplace.
Locating Your Fireplace
7. The venting system (chimney) of this fireplace should be
checked at least once a year and if needed your venting
system should be cleaned.
8. Keep the area around your fireplace clear of combustible
materials, gasoline and other flammable vapor and liquids.
This fireplace should not be used as a drying rack for cloth-
ing, nor should Christmas stockings or decorations be hung

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.
High Elevations
Input ratings are shown in BTU per hour and are
certified without deration for elevations up to
4,500 feet (1,370m) above sea level.
Remote ON/OFF Switch
For elevations above 4,500 feet (1,370m) in USA,
installations must be in accordance with the cur-
rent ANSI Z223.1/NFPA 54 and/or local codes hav-
ing jurisdiction.
Installation
1. Thread the wiring through the holes on the end
panels of the fireplace. Take care not to cut the wire
or insulation on metal edges. Route the wire to a
conveniently located receptacle box.
In Canada, please consult provincial and/or local
authorities having jurisdiction for installations at
elevations above 4,500 feet (1,370m).
2. Attach the wire to the ON/OFF switch and install the
switch into the receptacle box.
Gas Line Installation
3. Connect the other ends of the wire to the gas control
valve. (Fig. 6)
When purging the gas lines, the front win-
dow 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 ap-
proved 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 installa-
tion 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 pro-
vide 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 pres-
sure details and ratings.

General Venting
There must not be any obstruction such as bushes,
garden sheds, fences, decks or utility buildings within
24” (610mm) from the front of the termination hood.
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.
Do not locate termination hood where excessive snow
or ice build up may occur. Be sure to check vent termi-
nation area after snow falls, and clear to prevent ac-
cidental blockage of venting system. When using snow
blowers, make sure snow is not directed towards vent
termination area.
• 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.
Location of Vent Termination
It is imperative the vent termination be located observ-
ing the minimum clearances as shown on the next
page.
• Horizontal venting which incorporates the use of flex
venting shall have an inclining slope from the unit of
1” (25 mm) per 24” (610 mm).
*Check with local codes or in absence of same with
CSAB149.1 Installation Codes (1991) for Canada or fol-
low the current National Fuel Gas Code, ANSI Z223.1/
NFPA 54 for installations in the USA.

General Information Assembling Vent Pipes
* Be sure the vent is actually crushed before proceed-
ing. Apply a tug to be sure the vent will not slip off the
collars.
Canadian Installations:
Venting system must be installed in accordance with the
current CSA-B149.1 installation code.
Repeat process with 7” flex vent pipe. The same proce-
dure must be performed on the vent side.
USA Installations:
The venting system must conform with local codes and/
or the current National Fuel Gas code ANSI Z223.1/
NFPA 54.
Apply High Temperature
Sealant
Only venting components manufactured by CFM Corpo-
ration 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).
Hose Clamp
FP1471
*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 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.

How to Use the Vent Graph
Sidewall vent graph showing the relationship between vertical
and horizontal dimensions for a Direct Vent flue system.
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.
Fig. 13 Sidewall venting graph. (Dimensions in feet)
Rear Wall Venting Applications
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.
When installed as a rear vent unit this appliance may
be vented directly to a termination located on the rear
wall behind the appliance.
2. From the point of this intersection, draw a vertical
line to the bottom of the graph.
• Only CFM Corporation venting components are
approved to be used in these applications. (Refer to
“Venting Components” listed for different installation
requirements)
3. Select the indicated dimension, and position the
fireplace in accordance with same.
• 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)
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).
• Only one 45° elbow is allowed in these installations.
Example B:
• Minimum clearances between vent pipe and com-
bustible materials are as follows:
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).
Top - 2” (51 mm)
Sides - 1” (25 mm)
Bottom - 1” (25 mm)

STEP 3
Measure from the fireplace collar or elbow face to face
of outside wall (add 2” for vent pipe overlap). Mark
pipes and cut to length. It is very important that the two
pipes are flush with the outside wall once the fireplace
is in its final location. (Fig. 17)
NOTE: When using flex vent, the opening will have to
be measured according to the 1/2” (13 mm) rise in 12”
(305 mm) vertical run.
Combustible Walls (Fig. 15): Cut a 10³⁄₈”H x 9³⁄₈” W
(264 x 240 mm) hole through the exterior wall and
frame as shown.
STEP 4
Slip 4” and 7” pipes onto respective flue collars. Make
sure to fix to the fireplace collar the 4” pipe with three
(3) screws before fixing the 7” pipe on the 7” collar.
Both pipes must be on a level plane. (Fig 18)
Noncombustible Walls (Fig. 15): Hole opening must
be 7¹⁄₂” (190mm) in diameter.
STEP 2
STEP 5
Measure wall thickness and cut zero clearance sleeve
parts to proper length (MAXIMUM 12”/305 mm). As-
semble sleeve and attach to firestop with #8 sheet
metal screws (supplied). (Fig. 16)
Guide the vent termination 4” collar into the 4” pipe then
the 7” collar into the 7” pipe. Do not force the venting
into position. If the pipes do not line up with the termi-
nation collars, disassemble pipes and reattach to the
fireplace collar. (Fig. 18)

Follow Steps 1 and 2 on Page 13.
Step 3
Install the 4” (102mm) flex vent pipe to the appliance
collars described in “General Information Assembling
Vent Pipes”, Page 11. If the installation requires a 45°
angle, grasp the vent pipe close to the appliance collar
and bend to 45°. DO NOT exceed 45°. (Fig. 19)
The Vent Graph shows the relationship between vertical
and horizontal side wall venting and will help to deter-
mine the various dimensions allowable.
Minimum clearance between vent pipes
and combustible materials is 1”(25 mm)
on top, bottom and sides unless otherwise
noted.
Install the 7” vent pipe in the same manner as Step 2.
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.
NOTE: There must be a 1” (25 mm) rise in a 24”
(610mm) length of flex vent.
Step 4
Assemble the flex vent to the collars on the termination
as you did on the appliance.
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.

When it is not possible to meet the required vent ter-
minal clearances of 12” (305 mm) above grade level
a snorkel vent kit #7TDVSNORK is required. It allows
installation depth of down to 7” (178 mm) below grade
level. The 7” is measured from the center of the hori-
zontal vent pipe as it penetrates through the wall.
If venting system is installed below
ground, we recommend a window well with
adequate and proper drainage.
Ensure sidewall venting clearances are ob-
served.
The maximum horizontal run with 24”
vertical rise is 36” (914 mm) from the
back of the fireplace to the face of the
exterior wall. See vent graph (Page 12) for
extended horizontal run if the vertical rise
exceeds 24” (610 mm).
CFM137
Fig. 29 Apply high temperature sealant.
STEP 6
1. Establish vent hole through the wall. (Fig. 25)
Apply high temperature sealant to 4” (102 mm) and 7”
(178 mm) collars or the termination one inch away from
the end. Guide the vent termination’s 4” and 7” collars
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. (Fig. 30)
2. Remove soil to a depth of approximately 16”
(406mm) 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. 31)
3. Install vent system. See Page 13, Steps 2 through 5.
4. Ensure a watertight seal is made around the vent
pipe coming through the wall.
STEP 7
5. Apply high temperature sealant caulking (supplied)
around the 4” and 7” snorkel collars.
6. Slide into the vent pipe and secure to the wall.
Support the horizontal pipes every 36” (914 mm) with
metal pipe straps. Make sure that the horizontal vent
pipe is installed on a level horizontal plane.
7. Level the soil to maintain a 4” (102 mm) clearance
below snorkel. (Fig. 31)
STEP 8
Re-check the fireplace to make sure that it is levelled,
properly positioned, and nailed or screwed to the floor.
If applied, the fireplaces adjustable frame drywall strips
(nailing flanges) should be fastened. Refer to “Framing

behind the lower louvre assembly as in Figure 52
or located remotely in a conveniently located wall
mounted electrical box. Remote location of the
speed control will require suitable extension of the
component wiring.
1. Open the lower Louvre assembly. Move the fan &
bracket assembly around the gas valve and lines to
locate the unit against the back wall of the
appliance, resting on the base.
4. The power supply may be connected in two ways:
2. With the protective cover removed from the self-
adhesive ‘Velcro’ strips apply mild pressure to the
fan & bracket unit to secure the strips to the metal
panels. No further securing is required.

Route the 6’ lead fitted to the unit to a conveniently
located wall socket.
Method B (Using EB-1 Receptacle Box)
3. Power to the fan can be supplied by plugging the
supplied lead into a conveniently located wall socket
or by using a hard-wired EB-1 receptacle box.
The EB-1 receptacle box (Pt. # ZA1200) may be
hard wired into the house supply. The fan lead is
then plugged into the EB-1 box. For instruction
on wiring the EB-1 receptacle box see the earlier
chapter in the Installation section of this manual.
