Problem
Possible Causes
Solution
Burner output on “high”
setting is too low.
(Rumbling noise and
fluttering blue flame at
burner surface.)
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.
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.
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.
Contact your authorized Napoleon dealer for instructions
on ordering a replacement burner assembly.
Pilot will not light.
(if equipped)
Lack of gas.
Obstruction in pilot orifice.
Electrode wire loose or off.
Dirty pilot electrode.
Pilot is actually lit.
After turning pilot knob to high, wait approximately
20-30 seconds for air to purge the gas supply line while
pressing igniter. Fill propane cylinder. During initial set-
up or after tank has been refilled, it is best to light one
of the tube burners before lighting the pilot burner. This
enables the gas to reach the valves on the manifold more
quickly.
Clean pilot orifice.
Replace lead wire.
Clean pilot electrode.
The pilot flame, especially on natural gas units is very
difficult to see. Place your hand 1 in. (2.5 cm) above grill
surface over the pilot burner to feel for heat.
