BCDV36CFG TROUBLE SHOOTING GUIDE
SYMPTOM PROBLEM TEST SOLUTION
Carbon is being deposited on
glass, logs or combustion cham-
ber surfaces.
Air shutter has become
blocked
- Ensure air shutter opening is free of lint or other obstructions.
Flame is impinging on
the logs or combustion
chamber.
- Check that the logs are correctly positioned.
- 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 values.
- Check that the door gasketing is not broken or missing and that the seal
is tight.
- Check that both vent liners are free of holes and well sealed at all joints.
- Check that minimum rise per foot has been adhered to for any horizontal
venting.
Flames are very aggressive. Door is ajar - Tighten door clamps
Venting action is too great. - Restrict vent exit with restrictor plate. See Restricting Vents.
Main burner fl ame is a blue, lazy,
transparent fl ame.
Blockage in vent. - Remove blockage. In really cold conditions, ice buildup may occur on the
terminal and should be removed as required. Refer to Figure 24 to ensure
correct location of storm collars.
Incorrect installation (vertical
termination only).
White / grey fi lm forms. Sulphur from fuel is being
deposited on glass, logs or
combustion 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 perma-
nently marked.

SYMPTOM PROBLEM TEST SOLUTION
Main burner goes out; pilot stays
on.
Pilot fl ame is not large enough
or not engulfi ng the thermopile
- Turn up pilot fl ame.
- Replace pilot assembly.
Thermopile shorting - Clean thermopile connection to the valve. Reconnect.
- Replace thermopile / valve.
Remote wall switch wire is too
long; too much resistance in
the system.
- Shorten wire to correct length or wire gauge.
Faulty thermostat or switch. - Replace
Main burner goes out; pilot goes
out.
Refer to "MAIN BURNER GOES OUT; PILOT STAYS ON"
Vent is blocked - Check for vent blockage.
Vent is re-circulating - Check joint seals and installation.
4" fl exible vent has become
disconnected from fi replace.
- Re-attach to fi replace.
- 7"ø cap was not replaced
Pilot goes out when the gas knob
is released.
The gas valve has an interlock
device which will not allow the
pilot burner to be lit until the
thermocouple has cooled. Al-
low approximately 60 seconds
for the thermocouple to cool.
System is not correctly purged. - Purge the gas line.
Out of propane gas. - Fill the tank.
Pilot fl ame is not large enough - Turn up the pilot fl ame.
Pilot fl ame is not engulfi ng the
thermocouple.
- Gently twist the pilot head to improve the fl ame pattern around the
thermocouple.
Thermocouple shorting / faulty. - Loosen and tighten thermocouple.
- Clean thermocouple and valve connection.
- Replace thermocouple.
- Replace valve.
Faulty valve. - Replace.
Pilot burning; no gas to main
burner; gas knob is on 'HI'; wall
switch / thermostat is on.
Themostat or switch is defec-
tive.
- Connect a jumper wire across the wall switch terminals; if main burner
lights, replace switch / thermostat.
Wall switch wiring is defective. - Disconnect the switch wires & connect a jumper wire across terminals
1 & 3; if the main burner lights, check the wires for defects and / or
replace wires.
Main burner orifi ce is plugged. - Remove stoppage in orifi ce.
Faulty valve. - Replace.
BEFORE ATTEMPTING TO TROUBLESHOOT, PURGE YOUR UNIT AND INITIALLY LIGHT THE PILOT AND THE MAIN BURNER WITH THE GLASS DOOR OPEN.
