BCDV36CF / BCDV42CF TROUBLE SHOOTING GUIDE
SYMPTOM PROBLEM TEST SOLUTION
Pilot will not light No Spark at pilot burner - Check if pilot can be lit by a match
- Check that the wire is connected to the push button igniter.
- Check if the push button igniter needs tightening.
- Replace the wire if the wire insulation is broken or frayed.
- Replace the electrode if the ceramic insulator is cracked or broken.
- Replace the push button igniter.
Out of propane gas - Fill the tank.
Spark gap is incorrect - Spark gap should be 0.150" to 0.175" (5/32" to 11/64" approx.) from
the electrode tip and the pilot burner. To ensure proper electrode loca-
tion, tighten securing nut (fi nger tight plus 1/4 turn).
No gas at the pilot burner - Check that the manual valve is turned on.
- Check the pilot orifi ce for blockage.
- Replace the valve.
- Call the gas distributor.
Pilot goes out while standing;
Main burner is in 'OFF' position.
Gas piping is undersized. - Turn on all gas appliances and see if pilot fl ame fl utters, diminishes
or extinguishes, especially when main burner ignites. Monitor appliance
supply working pressure.
- Check if supply piping size is to code. Correct all undersized piping
Flames are consistently too large
or too small. Carboning occurs.
Unit is over-fi red or under-fi red. - Check pressure readings:
Inlet pressure can be checked by turning screw (A) counter-clockwise
2 or 3 turns and then placing pressure gauge tubing over the test point.
Gauge should read 7" (minimum 4.5") water column for natural gas or
13" (11" minimum) water column for propane. Check that main burner is
operating on "HI".
Outlet pressure can be checked the same as above using screw (B).
Gauge should read 3.5" water column for natural gas or 10" water col-
umn for propane. Check that main burner is operating on "HI".
AFTER TAKING PRESSURE READINGS, BE SURE TO TURN SCREWS
CLOCKWISE FIRMLY TO RESEAL. DO NOT OVER TORQUE.
Leak test with a soap and water solution.
Flames are very aggressive. Door is ajar - Tighten screws holding door in place
MODEL BCDV42CF ONLY:
Aggressive venting action due
to vent height.
- Restrict vent exit. See "RESTRICTING VERTICAL VENTS".
- VENT HEIGHT MORE THAN 15 FEET: restrict vent exit using restrictor
plate kit W500-0205
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.
Incorrect installation. - Refer to Figure ## to ensure correct location of storm collars.
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 4"/5" and 7" vent liners are free of holes and well
sealed at all joints.
- Check that minimum rise per foot has been adhered to for any horizon-
tal venting.
MODEL BCDV36CF(G) 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 permanently marked.
Exhaust fumes smelled in room,
headaches.
Fireplace is spilling. - Ensure exhaust bracket gasket seal
- Check door seal and relief fl ap seal.
- Check for chimney blockage
- Check that chimney is installed to building code.
- Room is in negative pressure; increase fresh air supply.
- Check 7"ø cap gasket on the fl ue pipe assembly.
Remote wall switch is in "OFF"
position; main burner comes on
when gas knob is turned to "ON"
position.
Wall switch is mounted upside
down
- Reverse.
Remote wall switch is grounding. - Replace.
Remote wall switch wire is
grounding.
- Check for ground (short); repair ground or replace wire.
Faulty valve. - Replace.
