Solution
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.
