Solution
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.
Pipe must be sized according to installation code.
Preheat grill with both main burners on high for 10 to
15 minutes.
Ensure sear plates are installed with the holes towards
the front and the slots on the bottom. See assembly
instructions.
Preheat grill with both main burners on high for 10 to
15 minutes.
Clean sear plates and drip pan regularly. Do not line
pan with aluminum foil. Refer to cleaning instructions.
Thoroughly clean burner by removing. See general
maintenance instructions. Open air shutter slightly
according to combustion air adjustment instructions.
(This must be done by a qualified gas installer.)
Replace with heavy duty 'AAA' battery.
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" (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. 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 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.
