Troubleshooting
Problem Possible Causes Solution
Low heat / Low
flame when valve
turned to high.
For propane - improper lighting
procedure.
For natural gas - undersized supply
line.
For both gases - improper
preheating.
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.
Pipe must be sized according to installation code.
Preheat grill with both main burners on high for 10 to
15 minutes.
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. Reguwlar 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.
