Gas supply.
Out of propane gas.
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
14" W.C. (34.9mb).
- Fill the tank.
