WARNING
• Always light the pilot whether for the fi rst time or if the gas supply has run out, with the glass door open or
removed.
• Turn off gas and electrical power before servicing the appliance.
• Appliance may be hot. Do not service until appliance has cooled.
• Do not use abrasive cleaners

symptom
problem
test solution
Main burner fl ame is a
blue, lazy, transparent
fl ame.
(This is not applicable
in outdoor appliances)
Blockage in vent.
-
Remove blockage. In really cold conditions, ice buildup may occur
on the terminal and should be removed as required. (To minimize this
from reoccuring, the vent lengths that pass through unheated spaces
(attics, garages, crawl spaces) should be wrapped with an insulated
mylar sleeve).
Incorrect installation.
-
Refer to “venting” section to ensure correct installation.
Flames are consistently
too large or too small.
Carboning occurs.
Appliance is over-fi red or under-
fi red.
-
Check pressure readings:
Inlet pressure can be checked by turning screw (A) counter-clock-
wise 2 or 3 turns and then placing pressure gauge tubing over the
test point. Gauge should read as described on the chart below.
Check that main burner is operating on ‘HI’. Outlet pressure can be
checked the same as above using screw (B). Gauge should read as
described on the chart below. Check that main burner is operating
on ‘HI’.
After taking pressure readings, be sure to turn screws
clockwise fi rmly to reseal. DO NOT OVER TORQUE.
Leak test with a soap and water solution.
Air shutter improperly adjusted.
-
Return air shutter to specifi ed opening, see “
venturi adjustments
”
section in the installation manual.
Carbon is being
deposited on glass,
logs, rocks, media, or
combustion chamber
surfaces.
Air shutter is blocked.
-
Ensure air shutter opening is free of lint or other obstructions.
Flame is impinging on the glass,
logs, rocks, media or combus-
tion chamber.
-
Ensure the media is positioned correctly in the appliance.
-
Open air shutter to increase the primary air.
-
Check the input rate: check the manifold pressure and orifi ce size as
specifi ed by the rating plate.
-
Ensure door gaskets are not broken or missing and the seal is tight.
-
Ensure vent liners are free of holes and well sealed at all joints.
-
Check that minimum rise per foot (meters) has been adhered to for
any horizontal venting.
White / grey fi lm forms.
Sulphur from fuel is being depos-
ited on glass, logs, or combus-
tion chamber surfaces.
-
Clean the glass with a recommended gas fi replace glass cleaner.
DO
NOT CLEAN GLASS WHEN HOT.
-
If deposits are not cleaned off regularly, the glass may become
permanently marked.
Exhaust fumes smelled
in room, headaches.
Appliance is spilling.
(This is not applicable in outdoor
appliances).
-
Check door seal.
-
Check for exhaust damage.
-
Check that venting is installed correctly.
-
Room is in negative pressure; increase fresh air supply.

symptom
problem
test solution
Pilot will not light. Makes
noise with no spark at
pilot burner.
Wiring: short, loose, or damaged
connections
(poor fl ame rectifi cation).
-
Verify the thermocouple/sensor is clean and the wiring is undamaged.
-
Verify the interrupter block is not damaged or too tight. Verify
connections from pilot assembly are tight; also verify the connections
are not grounding out to any metal. (Remember, the fl ame carries the
rectifi cation current, not the gas. If fl ame lifts from pilot hood, the circuit
is broken. A wrong orifi ce or too high of an inlet pressure can cause the
pilot fl ame to lift)*. The sensor rod may need cleaning.
No signal from remote with no
pilot ignition.
-
Reprogram receiver code.
-
Replace receiver.
Poor grounding.
-
Verify the valve / pilot assembly are properly grounded
Improper switch wiring.
-
Troubleshoot the system with the simplest
on/off
switch.
Dirty, painted, or damaged pilot
and/or dirty sensor rod.
-
Clean sensor rod with a green Scotch-Brite™ pad to remove any
contamination that may have accumulated. Verify continuity with
multimeter with ohms set at the lowest range.
Pilot sparks but will
not light.
Gas supply.
- Verify that the incoming gas line ball valve is “open”.
- Verify that the inlet pressure reading is within acceptable
limits, inlet pressures must not exceed 13” W.C. (32.4mb).
Out of propane gas.
- Fill the tank.
Pilot supply line may contain
air.
- Repeat ignition process several times or purge the pilot
supply line.
Incorrect wiring / grounding.
- Ensure correct polarity of wiring of thermocouple (if
equipped).
- Verify pilot assembly / valve are properly grounded.
Receiver (if equipped).
- Reset program: hold reset button on receiver and wait for 2
beeps. Release after second beep. Press small fl ame button
on remote within 20 seconds, you will hear an additional
beep (this signals a successful reset).
- Replace receiver.
Valve.
- Check valve and replace if necessary (Do not to overtighten
thermocouple).
Burner continues to
spark and pilot lights
but main burner
does not light.
Short or loose connection in
sensor rod.
- Verify all connections. Verify the connections from the pilot
assembly are tight. Also, verify these connections are not
grounding out to any metal.
Dirty, painted, or damaged
pilot assembly components.
- Clean using a green Scotch-Brite™ pad to remove any
contamination that may have accumulated on the sensor
rod, pilot hood, ignitor, or fl ame sensor. Verify continuity with
multimeter with ohms set at the lowest range.
Remote wall switch
is in “
off
