TROUBLE SHOOTING

ALWAYS LIGHT THE PILOT WHETHER FOR THE FIRST TIME OR IF THE GAS SUPPLY HAS RAN OUT,
SYMPTOM
Pilot will not light.
Makes noise with no
spark at pilot burner.
Pilot will not light.
Makes no noise with no
spark at pilot burner.
Pilot sparks but will not
light.
Carbon is being
deposited on glass, logs
or combustion chamber
surfaces.
W415-0825 / 07.06.09
WARNING
!
WITH THE GLASS DOOR OPEN OR REMOVED.
PROBLEM
Wiring.
Loose connection.
Module.
Igniter Spark gap is incorrect.
Transformer.
A shorted or loose
Connection.
Improper switch wiring.
Module is not grounded.
Faulty module.
Gas supply.
Module is not grounded.
Out of propane gas.
Air shutter has become
blocked.
Flame is impinging on the
logs or combustion chamber.
TEST SOLUTION
- Verify the "S" wire for the sensor and the "I" wire for
the ignitor are connected to the correct terminals (not
reverse) on the module and pilot assembly.
- Verify no loose connections, electrical shorts in the
wiring or ground out to any metal object.
- Turn the ON/OFF switch to the "OFF" position.
Remove the igniter wire "I" from the module. Place
the ON/OFF switch to the "ON" position. Hold a
grounded wire about 3/16" away from the "I" terminal
on the module. If no spark the "I" terminal module
must be replaced. If there is a spark the "I" terminal
is fi ne. Inspect pilot assembly for a shorted wire or
cracked insulator around the electrode.
- Spark gap of the ignitor to the pilot should be .17" tor 1/8"
- Verify the transformer is installed and plugged into the
module. Check voltage of the transformer under load at
the spade connections on the module with the ON/OFF
switch in the "ON" position. Acceptable readings of a
good transformer are between 3.2 and 2.8 volts A.C.
- Remove and reinstall the wiring harness that plugs
into the module. Remove and verify continuity of
each wire in wiring harness.
- Troubleshoot the system with the simplest ON/OFF switch.
- Verify the value and pilot assemblies are properly
grounded to the metal chassis of the fi replace or log set.
- Turn the ON/OFF switch to the "OFF" position.
Remove the igniter wire "I" from the module. Place
the ON/OFF switch to the "ON" position. Hold a
grounded wire about 3/16" away from the "I" terminal
on the module. If no spark the "I" terminal module
must be replaced. If there is a spark the "I" terminal
is fi ne. Inspect pilot assembly for a shorted wire or
cracked insulator around the electrode.
- 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 14" W.C.
- Verify the value and pilot assemblies are properly
grounded to the metal chassis of the fi replace or log set.
- Fill the tank.
- Ensure air shutter opening is free of lint or other
obstructions.
- 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.
