not light.
Carbon is being
deposited on glass,
media or combustion
chamber surfaces
Battery.
–
Wiring.
–
Loose connection.
–
Module.
–
Igniter spark gap is incorrect.
–
Electrode. –
A shorted or loose - connection.
–
Improper switch wiring.
–
Module is not grounded.
–
Gas supply.
–
Out of propane gas.
–
Air shutter has become - blocked.
–
Flame is impinging on the - glass, media
or combustion chamber.
–
Check batteries.
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.
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. Re-
move 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 termi-
nal module must be replaced. If there is a spark the
ignitor terminal is fine.
Spark gap of the ignitor to the pilot should be 1/8”
(3.2mm).
Inspect pilot assembly for a shorted wire or cracked
insulator around the electrode.
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 valve and pilot assemblies are properly
grounded to the metal chassis of the appliance
.
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.(34.9mb).
Fill the tank.
Ensure air shutter opening is free of lint or other
obstructions.
Check that the glass, logs, rocks or media are
correctly positioned.
Open air shutter to increase the primary air.
Check the input rate: check the manifold pressure and
orifice size as specified in the instructions.
