Problem Possible Causes Solution
“Paint” appears to be
peeling inside lid or hood.
Grease build-up on inside surfaces. 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.
Burner output on “high”
setting is too low.
(Rumbling noise and
fluttering blue flame at
burner surface.)
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.
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.
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.)
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.
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.
Pilot will not light.
(if equipped)
Lack of gas.
Obstruction in pilot orifice.
Electrode wire loose or off.
Dirty pilot electrode.
Pilot is actually lit.
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.
