Problem
Flames lift away from
burner, accompanied by the
smell of gas, and possibly
difficulties in lighting.
Burner will not light with the
igniter, but will light with a
match.
Humming regulator.
Burners will not crosslight
each other.
"Paint" appears to be
peeling inside lid or hood.
Burner output on "high"
setting is too low. (Rum-
bling noise and fluttering
blue flame at burner
surface.)
Infrared burner flashes
back (during operation the
burner abruptly makes a
loud "whoosh" sound,
followed by a continuous
blow-torch type sound and
grows dim.)
Possible Causes
Improper air shutter adjustment.
Dead battery / or installed
incorrectly.
Loose electrode wire.
Wrong replacement igniter.
Improper gap at electrode tip.
Lifting flames on burner.
Normal occurance on hot days.
Plugged ports along back of
burner.
Grease build up on inside
surfaces.
Lack of gas.
Supply hose is pinched.
Dirty or clogged orifice.
Spider webs in venturi tube, or
other foreign matter.
Cracked ceramic tile.
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
Close air shutter slightly according to combustion air
adjustment instructions.
(This must be done by a qualified gas installer.)
Replace with heavy duty 'AAA' battery. Install with positive
terminal up.
Check that electrode wire is firmly pushed onto the terminal
on the back of the igniter.
One spark systems must use a one spark igniter.
Ensure that the collector box is tight, and the gap between the
electrode end and the collector box is between 1/8 - 3/16".
The gap can be adjusted by bending the box in or out.
Close air shutter slightly - see previous problem
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.
Clean burner ports. See burner maintenance instructions.
This is not a defect. The peeling is caused by hardened
grease, which dries into paint-like shards, that will 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.
Order replacement burner from your Authorized Napoleon
dealer.
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 for ordering a replacement burner assembly.
