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 fine.
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.
- 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
orifice size as specified 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.
