Possible Causes
Normal occurrence on hot
days.
Dirty or corroded cross light
brackets.
Grease build-up on inside
surfaces.
Lack of gas.
Supply hose is pinched.
Dirty or clogged orifice.
Spider webs or other matter in
venturi tube.
Propane regulator in "low flow"
state.
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.
Solution
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 or replace as required.
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.
Check gas level in propane cylinder.
Reposition supply hose as necessary.
Clean burner orifice.
Clean out venturi tube.
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.
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.
