Troubleshooting
PROBLEM PROBLEM CAUSE SOLUTION
The flame and heat are
low when the valve is
turned to high.
The propane lighting
procedure was not followed
correctly.
Ensure lighting procedure is followed carefully. The valve
must be in the off position when the tank valve is turned on.
Turn the tank on slowly to allow pressure to equalize. See
Lighting Instructions in the Operating section.
Burners burn with yellow
flame, accompanied by
the smell of gas.
There is possibly a spider web
or other debris.
Thoroughly clean the burner venturi. See the Maintenance
section.
The burner will not light
with the igniter, but will
light with a match.
The battery is either dead or
installed incorrectly.
There is a loose electrode wire
or switch terminal wires.
Check the installation or replace with a new battery.
Check that the electrode wire is firmly pushed onto the
terminal on the back of the igniter. Check that the lead wires
from the module to the ignition switch (if equipped) are firmly
pushed onto their respective terminals.
The burner will not stay lit
when control knob is
released.
