Pilot is actually lit.
Solution
Replace with heavy duty battery.
Check that electrode wire is firmly pushed onto the
terminal on the back of the igniter. Check that the
lead wires from the module to the ignition switch (if
equipped) are firmly pushed onto their respective
terminals.
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" (3mm-5mm). 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. 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.
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.
Contact your authorized Napoleon dealer for
instructions on ordering a replacement burner
assembly.
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.
