SYMPTOM PROBLEM TEST SOLUTION
Pilot will not light.
Makes noise with
no spark at pilot
burner.
Wiring. - Verify the wire for the sensor and the wire for the ignitor are
connected to the correct terminals (not reversed) on the
module. NOTE: Sensor has 3/16” (4.8mm) connection and
ignitor has 1/8” (3.2mm)connection.
Loose connection. - Verify no loose connections, electrical shorts in the wiring or
ground out to any metal object.
Module. - Turn the ON/OFF switch to the “OFF” position. Remove the
igniter wire from the module. Place the ON/OFF switch to the
“ON” position. Hold a grounded wire about 3/16” (4.8mm)
away from the ignitor (spark) terminal on the module. If no
spark the ignitor terminal module must be replaced. If there is
a spark the ignitor terminal is fi ne. Inspect pilot assembly for a
shorted wire or cracked insulator around the electrode.
Ignitor Spark gap is incorrect. - Spark gap of the ignitor to the pilot should be 1/8” (3.2mm).
Transformer. - 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 6.2 and 7.0 volts A.C.
Battery backup (if power is off) - Check batteries.
A shorted or loose
Connection.
- Remove and reinstall the wiring harness that plugs into the
module. Remove and verify continuity of each wire in wiring
harness.
Improper switch wiring. - Troubleshoot the system with the simplest ON/OFF switch.
Module is not grounded. - Verify the valve and pilot assemblies are properly grounded to the
metal chassis of the appliance or log set.
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. (32.3mb).
Out of propane gas. - Fill the tank.
Carbon is be-
ing deposited on
glass, logs, rocks,
media or com-
bustion chamber
surfaces.
Air shutter has become
blocked.
- Ensure air shutter opening is free of lint or other obstructions.
Flame is impinging on the
glass, logs, rocks, media or
combustion chamber.
- Check that the glass, logs, rocks or media are correctly positioned.
- Too much glass media around the burner can cause carbon deposits.
- 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.
!
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 the gas and electrical power before servicing the appliance.
• Appliance may be hot. Do not service until appliance has cooled.
• Do not use abrasive cleaners.
