Problem Possible Causes Solution
Burners will not cross light
each other. Plugged ports along back of burner. Clean burner ports. See burner maintenance
instructions.
“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.
