14.0 TROUBLESHOOTING

ALWAYS LIGHT THE PILOT WHETHER FOR THE FIRST TIME OR IF THE GAS SUPPLY HAS RUN OUT,
TURN OFF THE GAS AND ELECTRICAL POWER BEFORE SERVICING THE APPLIANCE.
APPLIANCE MAY BE HOT, DO NOT SERVICE UNTIL APPLIANCE HAS COOLED.
SYMPTOM
Pilot will not light.
Makes noise with
no spark at pilot
burner.
IGNITOR
(SPARK)
SENSOR
PILOT
TUBE
Pilot sparks but
will not light.
Carbon is being
deposited on
glass, logs,
rocks, media
or combustion
chamber surfaces.
!
WITH THE GLASS DOOR OPEN OR REMOVED.
DO NOT USE ABRASIVE CLEANERS.
PROBLEM
Wiring.
Loose connection.
Module.
Igniter Spark gap is incorrect.
Transformer.
Battery backup (if power is
off)
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, logs, rocks, media or
combustion chamber.
WARNING
TEST SOLUTION
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. 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.
Spark gap of the ignitor to the pilot should be 1/8" (3.2mm).
-
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.
Check batteries.
-
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 or log set.
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).
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.
-
- 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.
