has an interlock
device which
will not allow
the pilot burner
to be lit until the

-
Fill the tank.
Pilot
fl
ame is not large
enough.
-
Turn up the pilot

ame.
Pilot
fl
ame is not engul

ng
the thermocouple
-
Gently twist the pilot head to improve the

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
