Troubleshooting

Possible Causes
For propane - improper lighting
procedure.
For natural gas - undersized supply
line.
Possible spider web or other debris.
Dead battery / or installed incorrectly.
Loose electrode wire or switch
terminal wires.
Improper gap at electrode tip.
Normal occurrence on hot days.
Lack of gas.
Supply hose is pinched.
Dirty or clogged orifice.
Spider webs or other matter in venturi
tube.
Propane regulator in "low flow" state.
Lack of gas.
Obstruction in pilot orifice.
Dirty pilot electrode.
Solution
Ensure lighting procedure is followed carefully. The
valve must be in the off position when the tank valve
is turned on. Turn tank on slowly to allow pressure
to equalize. See lighting instructions.
Pipe must be sized according to installation code.
Thoroughly clean burner venturi. See general
maintenance instructions.
Replace with heavy duty battery.
Check that 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 gap can be adjusted by bending the tip in or out.
Until a spark is achieved.
This is not a defect. It is caused by internal vibrations
in the regulator and does not affect the performance
or safety of the gas torch. Humming regulators will
not be replaced.
Check gas level in propane cylinder.
Reposition supply hose as necessary.
Clean burner orifice.
Clean out venturi tube.
Ensure lighting procedure is followed carefully. All
valves must be in the off position when the tank
valve is turned on. Turn tank on slowly to allow
pressure to equalize. See lighting instructions.
After turning pilot knob to high, wait approximately
20-30 seconds for air to purge the gas supply line
while pressing igniter.
Clean pilot orifice.
Clean pilot electrode.
