12.0 TROUBLE SHOOTING
SYMPTOM PROBLEM TEST SOLUTION
Main burner goes out;
pilot stays on. Pilot fl ame is not large enough or
not engulfi ng the thermopile. - Turn up the pilot fl ame.
- Replace pilot assembly.
Thermopile shorting. - Clean thermopile connection tot he valve. Reconnect.
- Replace thermopile / valve.
Remote wall switch wire is too long;
too much resistance in the system. - Shorten wire to connect length or wire gauge.
Faulty thermostat or switch. - Replace.
Vent safety switch has opened.

Faulty thermocouple - Replace.
Pilot goes out when the
gas knob is released.
The gas valve has an
interlock device which
will not allow the pilot
burner to be lit until
the thermocouple
has cooled. Allow
approximately 60
seconds for the
thermocouple to cool. System is not correctly purged. - Purge the gas line with the glass door open.
Out of propane gas. - Fill the tank.
Pilot fl ame is not large enough. - Turn up the pilot fl ame.
Pilot fl ame is not engulfi ng the
thermocouple - Gently twist the pilot head to improve the fl ame pattern
around the thermocouple.
Thermocouple shorting / faulty. - Loosen and tighten thermocouple.

Pilot will not light. No spark at pilot burner. - Check if pilot can be lit by a match.
- Check that the wire is connected to the push button igniter.
- Check if the push button igniter needs tightening.
- Replace the wire if the wire insulation is broken or frayed.
- Replace the electrode if the ceramic insulator is cracked or broken.
- Replace the push button ignitor
Out of propane gas. - Fill the tank.
Spark gap is incorrect. - Spark gap should be 0.150” to 0.175” (5/32” to 11/64” approx.) from the
electrode tip and the pilot burner. To ensure proper electrode location,
tighten securing nut (fi nger tight plus 1/4 turn).
No gas at the pilot burner. - Check that the manual valve is turned on.
