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 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.
