Solution
Check for spider webs in the burner or orifice.
Preheat grill with main burners on high for 5 to
10 minutes.
When cooking for long periods of time, or when
the cylinder is close to being empty, or low
outside air temperatures, 1 lb cylinders do not
have enough wetted surface area to allow liquid
propane to turn to vapor. Put on a fresh 1 lb
cylinder or hook-up to a 20 lb tank.
Preheat grill with both main burners on high for
5 to 10 minutes.
Clean 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.)
Clean jet-fire outlet with a soft bristle brush.
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.
This is not a defect. The peeling is caused by
hardened grease, which dries into paint-like
shards that flake off. Regular cleaning will
prevent this. See cleaning instructions.

Reposition supply hose as necessary.
Clean burner orifice.
