IMPORTANT:
PLEASE REVIEW THE FOLLOWING CAREFULLY
Remove any plastic from 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.
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.
Locating Your Fireplace
8. Keep the area around your fireplace clear of combustible
materials, gasoline and other flammable vapor and liquids.

4. Attach the fireplace nailing flanges to the frame as
shown in Figure 4.
1. Choose the unit location.
5. The gas components are located in the control
panel assembly attached to the right side of the unit.
Choose the desired location on the wall or mantel
for the valve box assembly. The conduit length is 5’
(1524 mm). (Fig. 6) The framing dimensions for the
box are 12¹⁄₄”L x 9¹⁄₄”W x 5⁵⁄₈”D (311 x 235 x 143 mm).
When the framing for the box is complete, remove
the screws securing the valve box to the outer cas-
ing. Carefully remove the valve box and, without
stressing the conduit, slide the box into the framed
opening. Replace the screws removed from the side
of the outer casing.
2. The unit is shipped with four (4) nailing flanges
mounted near the front corners on the side with the
valve box assembly . (Fig. 4)

Always check for gas leaks with a mild
soap and water solution applied with a
brush no larger than 1” (25mm). Never ap-
ply soap and water solution with a spray
bottle. Do not use an open flame for leak
testing.
Electrical Junction Box (E Units Only)
The fireplace, when installed, must be elec-
trically connected and grounded in accord-
ance with local codes or, in the absence
of local codes, with the current CSA C22.1
Canadian Electrical Code or the national
electrical code ANSI/NFPA No. 70 in the
USA.
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 from the gas line when
pressure testing.
It is strongly suggested that the wiring of
the Electrical Junction Box be carried out
by a licensed electrician. The box should
be near the valve box assembly to plug the
cord into.
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.
Ensure the power to the supply line has
been disconnected before commencing
this procedure.
When using copper, use only approved fittings. Always
provide a union when using black iron pipe so the gas
line can be easily disconnected for burner servicing. A
union may not be behind a wall. (Fig. 8) See the gas
specifications for pressure details and ratings.
Electronic Gas Control Valve
Remote ON/OFF Switch
This appliance may be fitted with a Honeywell ignition
module. The unit is shipped from the manufacturer with

higher, sealant (milpack or stove cement) to the joint of
the inner pipe (flue pipe) and the straight section as it is
impossible to be taped. The outer pipe must be taped
with 315°F high temperature metal adhesive tape for
proper sealing.
SK8 Venting Pipes
Canadian Installations:
The venting system must be installed in accordance
with the current CSA-B149 .1 installation code.
USA Installations:
Start by attaching the first vent pipe section to the collar
on top of the fireplace. In order to attach the first pipe
section, it may be necessary to remove the top shield.
Remove four (4) screws securing top shield, install first
pipe section and replace top shield.
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 Cor-
poration can be used in Direct Vent systems.
Install the pipe as shown in Figure 14. When you get a
good lock, you will hear the pipe clearly snap together.
Once sections are snap-locked in place, it is extremely
difficult to get them apart. Make sure the pipe is firmly
snapped and locked together as each pipe section is
mounted.
NOTE: The joints of the inner pipe (flue pipe) must be
taped with 550°F or higher temperature metal adhesive
tape that meets the requirements of F.A.R. 25.853(a).
High temperature sealant milpack or stove cement
of 550°F or higher could be used instead. The joints
of The outer pipe (fresh air pipe) must be taped with
315°F or higher temperature metal adhesive tape or the
use of high temperature milpack or stove cement would
be applicable. When using the unitized 30°, 45° or 90°
When installing elbows, follow the same procedure.

Operating Instructions
Glass Information
Glass Cleaning
Only glass approved by CFM Corporation
should be used on this fireplace.
It is necessary to periodically clean the glass. During
start-up, condensation, which is normal, forms on the
inside of the glass. This condensation causes lint,
dust and other airborne particles to cling to the glass
surface.
• The use of any non-approved replacement glass will
void all product warranties.
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 based
household cleaner and warm water (gas fireplace glass
cleaner is recommended) within the first few weeks of
operation.
• Care must be taken to avoid breakage of the glass.
• Do not operate appliance with glass front
removed, cracked or broken.
• A replacement glass frame assembly (complete
with gasket) is available through your CFM
Corporation dealer and should only be installed
by a licensed qualified service person.
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.
Glass Frame Assembly Removal
Clean the glass after the first two weeks of
operation.
1. Turn the fireplace OFF (including the pilot).
2. If the unit has been operating allow time for the
components to cool.
Restrictor Plates Installation
Refer to Page 12 for your venting configuration and
combination of restrictor plate requirement.
3. Using a Phillips screwdriver, unfasten two (2) screws
located at the top of the glass frame. (Fig. 38)
Restrictor Plate Installation
4. Tilt the glass frame at the top away from the unit.
Lift it carefully off the bottom door track and set on
padded surface.
Using the two (2) screws provided along with the restic-
tor plate shipped with the logset, fasten the restrictor
plate to the firebox top through the front of the unit. (Fig.

Troubleshooting the Gas Control System
SIT NOVA 820 MILLIVOLT VALVE
NOTE: Before trouble shooting the gas control system, be sure external gas shut off is in the “On” position.
Possible Causes
Corrective Action
Symptom
1. Spark ignitor will not light
A. Defective or misaligned electrode
at pilot
Using a match, light pilot. If pilot lights, turn off pilot and
push the red button again. If pilot will not light - check
gap at electrode and pilot-should be 1/8” to have a
strong spark.
With the control knob in the pilot position, push the
control knob all the way and hold. Check for spark at
electrode and pilot. If no spark to pilot, and electrode
wire is properly connected, replace the battery in the
ignitor module and try again. Refer toMaintenance
Section. If the problem still exists, replace the ignitor
module box.
B. Defective ignitor (Push Button)
Check pilot flame. Must impinge on thermocouple/ther-
mopile. NOTE: This pilot burner assembly utilizes both
a thermocouple and a thermopile. The thermocouple
operates the main valve operation (On and Off). Clean
and or adjust pilot for maximum flame impingement on
thermopile and thermocouple.
2. Pilot will not stay lit after
carefully following lighting
instructions
A. Defective pilot generator (thermo-
couple), remote wall switch
B. Defective automatic valve
Turn valve knob to “Pilot”. Maintain flow to pilot; millivolt
meter should read greater than 10mV. 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.
Check wall switch and wires for proper connections.
Jumper wire across terminals at wall switch, if burner
comes on, replace defective wall switch.. If okay,
jumper wires across wall switch wires at valve, if burner
comes on, wires are faulty or connections are bad.
3. Pilot burning, no gas to
main burner
A. Wall switch or wires defective
1. Be sure wire connections form thermopile at gas
valve terminals are tight and thermopile is fully
inserted into pilot bracket.
B. Thermopile may not be generat-
ing sufficient millivoltage
2. One of the wall switch wires may be grounded. Re-
move wall switch wires form 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.
Turn valve knob to “On”, place wall switch to “On”
millivolt meter should read greater than 150mV. If the
reading is okay and the burner does not come on,
replace the gas valve.
D. Defective automatic valve opera-
tor
Clean and/or adjust pilot flame for maximum flame
impingement on thermopile and thermocouple.
A. Pilot flame may be too low or
blowing (high) causing the pilot
safety to drop out
4. Frequent pilot outage
problem
B. Possible blockage of the vent
terminal
Check the vent terminal for blockage (recycling the flue
gases).

Maintenance
Burner and Burner Compartment
Typically, the top 3/8” to 1/2” of the thermopile/sensing
electrode should be engulfed in the pilot flame. (Refer
to Page 26, Figure 54)
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 refit the logs as per the instructions in this manual.
To adjust pilot burner: (by qualified service technician)
1. Remove pilot adjustment cap
2. Adjust pilot screw to provide properly sized flame.
3. Replace pilot adjustment cap.
Always handle the logs with care as they
are fragile and may also be hot if the
fireplace has been in use.
Cleaning Electronic Ignition System
The Electronic Ignition burner/control system consists
of:
Cleaning the Standing
Pilot Control System
• main burner
• gas orifice
The burner and control system consist of:
• burner tube
• gas orifice
• pilot burner
• pilot assembly • thermopile
• gas valve
Most of these components may require only an
occasional checkup and cleaning and some may
require adjustment. If repair is necessary, it should
be performed by a qualified technician.
• 24VAC valve with transformer
Taking care of the Electronic Ignition units is identical to
taking care of the Standing Pilot models.
Battery Replacement for Ignitor Module
1. Open control panel box door.
2. Remove the extension knob(s).
1. Turn off pilot light at gas valve.
2. Allow fireplace to cool if it has been operating.
3. Remove the valve cover by removing the two (2)
screws securing the valve cover plate to the box.
While holding the valve cover plate with one hand,
disconnect the wiring to the switch and the pilot
indicator. NOTE: Do not allow the valve cover plate
to hang from the pilot indicator wires as this could
damage the wires.
3. Remove window frame assembly. (Refer to Window
Frame Assembly Removal section.)
4. Remove logs.
5. Vacuum burner compartment especially around
orifice primary air openings.
6. Visually inspect pilot. Brush or blow away any dust
or lint accumulation.
4. Replace the battery (AA) in the ignitor module lo-
cated at the top left corner.
7. Reinstall logs.
8. Ignite pilot - Refer to Lighting Instructions.
9. Reinstall window frame assembly.
5. Replace wires, valve cover, extension knob(s) in
reverse order. NOTE: The pilot indicator body is
labelled +/-, make sure the positive wire on the pilot
indicator goes to ground and the negative goes to
the plug between the valve and the thermocouple.
To obtain proper operation, it is imperative that the pilot
and burner’s flame characteristics are steady, not lifting
or floating.

CAUTION: If you are framing with the plan to use the
CHFN0495, CHWC495, CHFPR495 surround mantel,
it is extremely critical to meet the dimensions provided,
especially if the mantel is not available at the time of
framing. A framing stud is allowed to be placed on
the inside of the 6” (152 mm) standoff on the side
of the unit where the conduit is located to meet the

NOTE: The vertical dimension is shown from the floor
where the fireplace sits. If a marble hearth extension, or
other type of material is used, the vertical framing will
increase by the thickness of the material used to ac-
commodate the height difference when the mantel sits
on the hearth extension.
The unit is certified with a 3” (76 mm) standoff (to
combustible) on the side of the unit where the conduit is
located, therefore; it is permissible to locate stud on the
inside of the standoff at 3” (76 mm) from the body of the
unit. (Fig. 63)
NOTE: The 6” (152 mm) standoff is sent out with the
unit for the purpose of making the glass symmetrical
with respect to the overall width of the unit.
