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.
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.
