IMPORTANT:
PLEASE REVIEW THE FOLLOWING CAREFULLY
FOR SAFE INSTALLATION AND OPERATION PLEASE
Remove any plastic from trim parts before turning the
fireplace ON.
NOTE THE FOLLOWING:
1. This fireplace gives off high temperatures and should be
located out of high traffic areas and away from furniture and
draperies.
2. Children and adults should be alerted to the hazards of high
surface temperatures of this fireplace and should stay away

4. Under no circumstances should this fireplace be modified.
Parts removed for servicing should be replaced prior to
operating this fireplace again.
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.
5. Installation and any repairs to this fireplace must be per-
formed by a qualified installer, service agency or gas sup-
plier. A professional service person should be contacted to
inspect this fireplace annually. Make it a practice to have
all of your gas fireplaces checked annually. More frequent
cleaning may be required due to excess lint and dust from
carpeting, bedding material, etc.
6. Control compartments, burners and air passages in this fire-
place 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.

dow frame assembly must be removed.
FP1539
Fig. 4 Nailing flanges.
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.
Final Finishing
Noncombustible materials such as brick or tile may be
extended over the edges of the face of the fireplace.
DO NOT cover any vent or grille panels.
If a Trim Kit is going to be installed on the fireplace, the
brick or tile will have to be installed flush with the edges
of the fireplace.
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.

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.
• If vent termination is installed in an accessible loca-
tion, Vent Termination Guard #53525 shall be in-
stalled.
• Vent terminations shall not be recessed into a wall or
siding.
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 twist lock
pipe must be installed on a level plane without an
inclining or declining slope.
*Check with local codes or in absence of same with
CSA B149.1 Installation Codes (1991) for Canada
or follow the current National Fuel Gas Code, ANSI
Z223.1/NFPA 54 for installations in the USA.
• 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).

General Information Assembling Vent Pipes
Canadian Installations:
* Be sure the flex vent is flat and flush with the flue or
outer collar before proceeding. Apply a tug to be sure
the vent will not slip off the collars.
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.
Only venting components manufactured by CFM Corpo-
ration can be used in Direct Vent systems.
Hose
Clamp
Flex Vent Pipes
Apply High Tem-
perature Sealant
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” (25 mm) onto
the collars of the fireplace and termination. If the ter-
mination has an internal bead, be sure to overlap and
secure 1” (25 mm) 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. 10 Sidewall venting graph. (Dimensions in feet)
Vertical Sidewall 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. 10)
locate the point intersecting with slanted graph line.
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.
2. From the point of this intersection, draw a vertical
line to the bottom of the graph.
The Vent Graph shows the relationship between vertical
and horizontal side wall venting and will help to deter-
mine the various dimensions allowable.
3. Select the indicated dimension, and position the
fireplace in accordance with same.
Minimum clearance between vent pipes and com-
bustible materials is 1”(25 mm) on top, bottom and
sides unless otherwise noted.

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).
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.
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).
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.

Example: According to the vent graph (Page 10) 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 13 Dimension A plus B must not be
greater than 17’ (5.2 m).
Horizontal plane means no vertical rise exists on this
portion of the vent assembly.
• The maximum number of 90° elbows per side wall
installation is three (3). (Fig. 11)
• If a 90° elbow is fitted directly on top of the fireplace
flange, the maximum horizontal vent run before the
termination or a vertical rise is 36” (914 mm). (Fig.
12)
• 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.
• 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. 12)
This does not apply if the 90° elbows are used to
increase or redirect a vertical rise. (Fig. 13)
• 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. 14)
Example:
3 x 90° Elbows
Elbow 1 = 90°
Elbow 2 = 45°
Elbow 3 = 45°
Elbow 4 = 90°
Total angular variation = 270°

Locate vent opening on the wall. It may be necessary
to first position the fireplace and measure to obtain hole
location. Depending on whether the wall is combustible
or noncombustible, cut opening to size. (Fig. 15) (For
combustible walls first frame in opening.)

STEP 4
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. As an alterna-
tive to screwing the termination directly to the wall, you
may also use expanding plugs or an approved exterior
construction adhesive. You may also attach the termina-
tion with screws through the inner body into the 4” vent
pipe, however for this method, you must extend the 4”
pipe approximately 6” (152 mm) beyond the outer face of
the wall.
Install the 4” (102 mm) flex vent pipe to the appliance
collar as described on Page 13. Secure the end with the
first spring 6³⁄₄” (172 mm) from the flex pipe end to the
unit.
STEP 5
Slide the 7” (178 mm) flex vent pipe over the 4” flex vent
pipe and secure 7” collar as described on Page 14.
STEP 6
Bend the flex pipe horizontal so the bottom of the hori-
zontal pipe measures 6¹⁄₂” (165 mm) from the top of the
unit immediately after the 90° formation. (Fig. 20) Be
sure to follow the 1/2” (13 mm) rise in a 12” (305 mm)
horizontal run rule.

Install the four (4) spacer springs on the 4” flex vent
pipe. When installing the spacer springs around the 4”
pipe, stretch the spring to approximately 15” (381 mm),
wrap the spring around the pipe and interlock the ends
of the spacer spring approximately 2” (51 mm). Mea-
sure 6³⁄₄” (172 mm) from the end of the pipe. Place the
next spring 5” (127 mm) from the previously installed
spring. Place the next spring 6” (152 mm) from the last
spring. Finally, place the last spring 12” (305 mm) from
the last spring installed. (Fig. 19)
Fig. 20 Bend flex vent at 90° so horizontal portion is 6¹⁄₂”
(165 mm) off top of unit.
Below Grade Installations
When it is not possible to meet the required vent ter-
minal 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 recom-
mend a window well with adequate and proper drainage
to be installed around the termination.
4” Flex Vent Pipe

fireplace.
It is necessary to clean the glass periodically. During
start-up condensation, which is normal, forms on the
inside of the glass and causes lint, dust and other
airborne particles to cling to the glass surface. Also
initial paint curing may deposit a slight film on the glass.
It is therefore recommended the glass be cleaned
two or three times with a non-ammonia household
cleaner and warm water (gas fireplace glass cleaner
is recommended). After the initial cleaning process the
glass should be cleaned two or three times during each
operating season depending on the environment in the
house.
To remove the
cast front assem-
bly, pull cast front
up then lift out.

wire is properly connected, replace ignitor.
2. Pilot will not stay lit after
carefully following lighting
instructions.
A. Defective pilot generator
(thermocouple), remote wall
switch.
Check pilot flame. Must impinge on thermocouple/
thermopile. NOTE: This pilot burner assembly
utilizes both a thermocouple and a thermopile.
The thermocouple operates the main valve opera-
tion (ON/OFF). Clean and/or adjust pilot for maxi-
mum flame impingement on thermopile and thermo-
couple.
B. Defective automatic valve
Turn valve knob to “Pilot.” Maintain flow to pilot;
millivolt meter should read greater than 10 mV. If
the reading is okay and the pilot does not stay on,
replace the gas valve. NOTE: An interrupter block
(not supplied) must be used to conduct this test.
3. Pilot burning, no gas to
main burner
A. Wall switch or wires defective
Check wall switch and wires for proper connections
Jumper wires across terminals at wall switch; if
burner comes on, repalce defective wall switch. If
okay, jumper wires across wall switch wires at valve;
if burner comes on, wires are faulty or connections
are bad.
B. Thermopile may not be
generating sufficient
millivoltage.
1. Be sure wire connections from thermopile at
gas valve terminals are tight and thermopile is
fully inserted into pilot bracket.
2. One of the wall switch wires may be grounded.
Remove wall switch wires from valve terminals if
pilot now stays lit, trace wall switch wiring for
ground. May be grounded to fireplace or gas
supply.
3. Check thermopile with millivolt meter. Take
reading at thermopile terminals of gas valve—
should read 250-300 millivolts (minimum 150)
while holding valve knob depressed in pilot
position and wall switch “OFF.” Replace faulty
thermopile if reading is below specified minimum.
C. Plugged burner orifice.
Check burner orifices for debris and remove.
D. Defective automatic valve
operator.
Turn valve knob to “ON,” place wall switch to “ON” —
millivolt meter should read greater than 100 mV. If
the reading is okay and the burner does not come
on, replace the gas valve.
4. Frequent pilot outage
problem.
A. Pilot flame may be too low
or blowing (high) causing the
pilot safety to drop out.
Clean and/or adjust pilot flame for maximum flame
impingement on thermopile and thermocouple.
B. Possible blockage of the vent
terminal.
Check the vent terminal for blockage (recycling the
flue gases)
C. Low gas supply pressure
Check gas supply pressure to be between minimum
and maximum with the burner in the “ON” position.

and burner’s flame characteristics are steady, not lifting
or floating.
It is important to keep the burner and the burner
compartment clean. At least once per year the logs and
lava rock/ember material should be removed and the
burner compartment vacuumed and wiped out. Remove
and replace the logs as per the instructions in this
manual.
Typically, the top 3/8” or 1/2” of the thermopile should
be engulfed in the pilot flame. (Fig. 43)
To adjust pilot burner; (by qualified service technician)
