Possible Causes
Dead battery / or installed incorrectly.
Loose electrode wire or switch terminal
wires.
Lifting flames on burner.
Jet-fire outlet is dirty or clogged.
Normal occurrence on hot days.
Dirty or corroded cross light brackets.
Grease build-up on inside surfaces.
Lack of gas.
Supply hose is pinched.
Dirty or clogged orifice.
Spider webs or other matter in venturi
tube.
Universal Liquefied Petroleum Gas
regulator in "low flow" state.
Ceramic tiles overloaded with grease
drippings and build-up. Ports are
clogged.
Burner overheated due to inadequate
ventilation (too much grill surface
covered by griddle or pan.)
Cracked ceramic tile.
Leaking gasket surrounding the ceramic
tile, or a weld failure in the burner
housing.
Solution
Replace with premium 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.
Close air shutter slightly - see previous
problem.
Clean jet-fire outlet with a soft bristle brush.
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 grill.
Humming regulators will not be replaced.
Clean or replace as required.
This is not a defect. The finish on the lid
and hood is porcelain, and will not peel.
The peeling is caused by hardened grease,
which dries into paint-like shards, that flake
off. Regular cleaning will prevent this. See
cleaning instructions.
Check gas level in Universal Liquefied
Petroleum Gas cylinder.
Reposition supply hose as necessary.
Clean burner orifice.
Clean out venturi tube.
Ensure lighting procedure is followed carefully.
All gas grill 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.
Turn burner off and allow to cool for at least
two minutes. Relight burner and burn on high
for at least five minutes or until the ceramic
tiles are evenly glowing red.
Ensure that no more than 75% of the grill
surface is covered by objects or accessories.
Turn burner off and allow to cool for at least
two minutes, then relight.
Allow burner to cool and inspect very closely
for cracks. If any cracks are found, contact
your authorized Napoleon dealer to order a
replacement burner assembly.
