Problem
Burners will not cross light
each other.
"Paint" appears to be peeling
inside lid or hood.
Burner output on "high"
setting is too low. (Rumbling
noise and fluttering blue
flame at burner surface.)
Infrared burner (if
equipped) flashes back
(during operation the
burner abruptly makes
a loud "whoosh" sound,
followed by a continuous
blow-torch type sound and
grows dim.)
Pilot will not light.

Possible Causes
Dirty or corroded cross light brackets. Clean or replace as required.
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.
