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.
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.
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.
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.
