Problem Possible Causes Solution
Excessive flare-ups/
uneven heat.
Sear plates installed incorrectly.
Improper preheating.
Excessive grease and ash build on sear
plates and in drip pan.
Ensure sear plates are installed with the
holes towards the front and the slots on
the bottom. See assembly instructions.
Preheat grill with both main burners on
high for 10 to 15 minutes.
Clean sear plates and drip pan regularly.
Do not line pan with aluminum foil. Refer
to cleaning instructions.
Burners burn with yellow
flame, accompanied by
the smell of gas.
Possible spider web or other debris, or
improper air shutter adjustment.
Thoroughly clean burner by removing.
See general maintenance instructions.
Open air shutter slightly according to
combustion air adjustment instructions.
(This must be done by a qualified gas
installer.)
Flames lift away from
burner, accompanied
by the smell of gas, and
possibly difficulties in
lighting.
Improper air shutter adjustment. Close air shutter slightly according to
combustion air adjustment instructions.
(This must be done by a qualified gas
installer.)
Humming regulator. Normal occurrence 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 cross
light 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 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.
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.
