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.)
Close air shutter slightly according to combustion
air adjustment instructions. (This must be done by
a qualified gas installer.)
Replace with premium 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.
Close air shutter slightly - see previous problem.
Clean jet-fire outlet with a soft bristle brush.

performance or safety of the gas grill. Humming
regulators will not be replaced.
Clean or replace as required.
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.
