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.
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.
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.
Check gas level in propane
cylinder.
Reposition supply hose as
necessary.
Clean burner orifice.
Clean out venturi tube.
