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

- Cap was not replaced.
Pilot goes out when the
gas knob is released.
The gas valve has an
interlock device which
will not allow the pilot

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).
