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.
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.
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.
