Plugged ports at back of burner.

Ceramic tiles overloaded with
grease drippings and build-up. Ports
are clogged.

inadequate ventilation (too much
grill surface covered by griddle or
pan.)

Solution
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.
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.
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.)
Close air shutter slightly according to combustion air
adjustment instructions. (This must be done by a
qualified gas installer.)
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.
Clean burner ports. See burner maintenance
instructions.
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.
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.
