Problem Possible Causes Solution
Low heat / Low flame when
valve turned to high.
For propane - improper lighting
procedure.
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.
For natural gas - undersized
supply line.
Pipe must be sized according to installation code.
For both gases - improper
preheating.
Pre-heat grill with both main burners on high for 10 to 15
minutes.
Excessive flare-ups/uneven
heat.
Sear plates installed incorrectly.
Ensure sear plates are installed with the holes towards the
front, and the slots on the bottom. See assembly
instructions.
Improper pre-heating.
Pre-heat grill with both main burners on high for 10 to 15
minutes.
Excessive grease and ash build

pan.
Clean sear plates and drip pan regularly. Do not line pan
with aluminum foil. Refer to cleaning instructions.

TROUBLESHOOTING
Normal occurence on hot days.
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.
Burners will not crosslight
each other.
Plugged ports at 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
stainless steel, and will not peel. The peeling is caused
by hardened grease, which dries into paint-like shards,
that will flake off. Regular cleaning will prevent this. See
cleaning instructions.
Regulator ‘Hums’ when
unit is operating.
Infrared burner 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.
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.
Burner overheated due to
inadequate ventilation (too
much grill surface covered by
griddle or pan.)
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.
Cracked ceramic tile.
Allow burner to cool and inspect very closely for cracks. If
any cracks are found, contact your authorized Napoleon
dealer for ordering a replacement burner assembly.
Leaking gasket surrounding the
ceramic tile, or a weld failure in
the burner housing.
Contact your authorized Napoleon dealer for instructions
on ordering a replacement burner assembly.
