Possible Causes
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.
Propane 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.
Lack of gas.
Obstruction in pilot orifice.
Electrode wire loose or off.
Dirty pilot electrode.
Pilot is actually lit.
Solution
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 propane 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.
Contact your authorized Napoleon dealer
for instructions on ordering a replacement
burner assembly.
After turning pilot knob to high, wait
approximately 20-30 seconds for air to
purge the gas supply line while pressing
igniter. Fill propane cylinder. During initial
set-up or after tank has been refilled, it is
best to light one of the tube burners before
lighting the pilot burner. This enables the
gas to reach the valves on the manifold
more quickly.
Clean pilot orifice.
Replace lead wire.
Clean pilot electrode.
The pilot flame, especially on natural gas
units is very difficult to see. Place your hand
1 in. (2.5 cm) above grill surface over the
pilot burner to feel for heat.
