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 -

General Information Assembling Vent Pipes
Canadian Installations:
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.
Venting system must be installed in accordance with the
current CSA-B149.1 installation code.
USA Installations:
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.
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.
Male End
Female End
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.
TWL100
Screw Holes
Fig. 13 Twist-lock pipe joints.
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

How to Use the Vent Graph
Rear Wall Venting Applications
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.
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)
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. 14)
locate the point intersecting with slanted graph line.
• 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” (508 mm). (Fig. 15 & 16)
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.
• Only one 45° elbow is allowed in these installations.
• If using a 45° elbow at fireplace, you must start
out using an 8” (203 mm) or 12” (305 mm) sec-
tion of pipe first attached to heater then a 45°
elbow.
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).
• Minimum clearances between vent pipe and com-
bustible materials are as follows:
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).
Top - 2” (51 mm)
Sides - 1” (25 mm)
Bottom - 1” (25 mm)

Example: According to the vent graph (Page 11) 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 21 Dimension A plus B must not be
greater than 17’ (5.2 m).
Vertical Sidewall Applications
Since it is very important for the venting system
to maintain balance between the combustion air
intake and the flue gas exhaust, certain limitations
as to vent configurations apply and must be strictly
adhered to.
In Figure 21, dimension A plus B must not be greater
than 17’ (5.2 m).
The Vent Graph shows the relationship between vertical
and horizontal side wall venting and will help to deter-
mine the various dimensions allowable.
• 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.
Minimum clearance between vent pipes and com-
bustible materials is 2”(51 mm) on top and 1” (25
mm) on the bottom and sides unless otherwise
noted.
• 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.
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 maximum number of elbow degrees in a system
is 270°. (Fig. 22)
Example:
Elbow 1 = 90°
Elbow 2 = 45°
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.
Elbow 3 = 45°
Elbow 4 = 90°
Total angular variation = 270°
Horizontal plane means no vertical rise exists on this
portion of the vent assembly.
B 7’
(178 cm)
A 10’
(254 cm)
When installing the appliance as a rear
vent unit, the 90° or 45° transition elbow
is NOT INCLUDED in the following criteria
and calculations, and unless specifically
mentioned should be ignored when calcu-
lating venting layouts.
A + B = 17’

not apply if the 90° elbows are used to increase or
redirect a vertical rise. (Fig. 21)

Do not backfill around snorkel.
Below Grade Installations
A clearance of at lest 4” must be main-
tained between the snorkel and the soil.
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.
If the foundation is recessed, use recess brackets (not
supplied) for securing lower portion of the snorkel. Fas-
ten brackets to wall first, then secure to snorkel with self
drilling #8 x 1/2 sheet metal screws. It will be necessary
to extend vent pipes out as far as the protruding wall
face. (Fig. 24)
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.
If installing a snorkel, a minimum 24” (610 mm) vertical
rise is necessary. The maximum horizontal run with the
24” vertical pipe is 36” (914 mm). This measurement
is taken from the collar of the fireplace (or transition
elbow) to the face of the exterior wall. See the Sidewall
Venting Graph for extended horizontal run if the vertical
exceeds 24” (610 mm).

Operating Instructions
Glass Cleaning
Glass Information
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.
Only glass approved by CFM Corporation
should be used on this fireplace.
• The use of any non-approved replacement glass will
void all product warranties.
• Care must be taken to avoid breakage of the glass.
• Do not operate appliance with glass front
removed, cracked or broken.
• Replacement glass (complete with gasket and
window frame) is available through your CFM
Corporation dealer and should only be installed
by a licensed qualified service person.
Clean the glass after the first two weeks of
operation.
Do not clean glass when hot.
Do not use abrasive cleaners.
Do not strike or slam the glass.

Inspecting the Venting System
Flame Characteristics
This appliance venting system is designed and con-
structed to develop a positive flow adequate to remove
flue gases to the outside atmosphere.
It is important to periodically perform a visual check of
the pilot and the burner flames. Compare them to Fig-
ures 34-35. If any of the flames appear abnormal call a
service person.
Any foreign objects in the venting system, except those
designed specifically for the venting system, may cause
spillage of flue gases.
To inspect the venting system, make sure the main gas
valve is off. Remove window frame assembly (Refer to
Window Frame Assembly Removal Section). Using a
flashlight, check the area above the baffle in the com-
bustion dome. Clean if necessary.

Troubleshooting
AF4000 Valve
If erratic system behavior is observed that cannot be resolved by the methods outlined below, ensure that there is
not a transmitter with batteries installed that may be interfering. If a transmitter is packed with batteries installed, its
buttons may be depressed sending a constant signal which can interfere with the transmission of desired signals. A
transmitter with new batteries can have a range of over 100’ (30.4 m).
Module will not learn trans-
mitter
• Ensure the REMOTE/OFF switch on the side of the module (Fig. 36) is set to RE-
MOTE.
• Make sure the batteries in both the transmitter and receiver are installed in the
proper direction (Fig. 39, 40) and are not drained. Individual battery voltage should
be no less than 1.4V for AA and AAA batteries, 2.8V for button cells, and 9,0V for
12V batteries.
• Verify the transmitter indicates a signal is being sent. With thermostat transmitters,
the LCD display should indicate ON or OFF depending on which button is being
pressed. The LED indicator should illuminate on wall transmitters and on/off hand-
held transmitters. (Fig. 39) Buttons should be pressed and held for 1 to 2 seconds
to ensure a complete signal is sent.
• Make sure the transmitter is within the 20’ (6 m) operational range of the receiver.
• Ensure the 4-pin lead-set is securely connected from the battery pack to the con-
trol module’s AUX connection. (Figs. 37) If the A/C power adapter is used, make
sure the leads from the adapter are securely connected to the POWER terminals
on the control module. (Fig. 38)
• Press and hold the LEARN button on the module (Fig. 37) for approximately 10
seconds to clear the memory (you should hear a series of beeps from the re-
ceiver). Then press and release the learn button (you should hear a single beep
from the receiver), immediately press either the ON or OFF button on the transmit-
ter (you should hear a series of beeps indicating the transmitter code has been
learned).

Troubleshooting AF4000 Valve (continued)
Pilot will not light/stay lit
• Verify the gas supply is turned on.
• Verify the receiver is receiving the signal from the transmitter by listening for a
beep from the receiver when ON is pressed on the transmitter. If you do not hear
a beep, ensure the module has learned the transmitter (see above).
• Ensure the orange lead from the pilot assembly igniter is securely connected to
the terminal labeled “I” and the white lead from the flame rectification sensor is
securely connected to the terminal labeled “S” on the control module. (Fig. 36)
• Make sure the orange and white leads from the module are securely connected to
the terminals labeled “PILOT” on the valve body. (Fig. 41)
• Ensure the black GROUND wire is securely connected to an appropriate metal
portion of the valve or pilot assembly. A proper ground is essential to spark
igniter operation.
• Make certain the pilot flame is in contact with the flame rectification sensor on the
pilot assembly. This valve is equipped with a pilot flame adjustment screw. (Fig.
41) If the pilot flame is too small it will not contact the flame rectification sensor
and will not complete the safety circuit.

Troubleshooting AF4000 Valve (continued)
• Ensure the CONTINUOUS PILOT switch on the control module (Fig. 36) is set
to OFF.
Pilot flame is always on/ will
not extinguish
• Verify the gas supply is turned on.
Main flame will not light
• Ensure the pilot flame will ignite. If not, see pilot flame troubleshooting above.
• Make sure the green and white leads from the module are securely connected to
the terminals labeled “MAIN: on the valve body. (Fig. 41)
• Make certain the pilot flame is in contact with the flame rectification sensor on
the pilot assembly. This valve is equipped with a pilot flame adjustment screw.
(Fig. 41) If the pilot flame is too small it will not contact the flame rectification
sensor and will not complete the safety circuit.
• Ensure the pilot flame is properly located to ignite the main flame.
• Ensure the black and red leads from the battery pack or the AF4000 110H/L
module are securely connected to the red and black leads from the motor drive
or H/L latching solenoid located on the valve body (red to red and black to
black).
Flame height adjustment will
not work/works backwards
• Verify the selector switch on the battery pack is set to DC MOTOR DRIVE or
LATCHING SOLENOID, depending upon which device is installed. (Fig. 40)
• Check functionality with all transmitters to determine if there is an issue with the
main control system or an individual transmitter. If the issue is with an individual
transmitter, make sure the batteries in both the transmitter and receiver are in-
stalled in the proper direction (Fig. 39, 40) and are not drained. Individual battery
voltage should be no less than 1.4V for AA and AAA batteries, 2.8V for button
cells, and 9.0V for 12V batteries.

Maintenance
To obtain proper operation, it is imperative that the pilot
and burner’s flame characteristics are steady, not lifting
or floating.
Burner and Burner Compartment
It is important to keep the burner and the burner
compartment clean. At least once per year the burner
