Possible Causes 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.

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.
Close air shutter slightly - see previous problem.

the regulator and does not affect the performance or
safety of the gas grill. Humming regulators will not be
replaced.
Clean or replace as required.
This is not a defect. The finish on the lid and hood is
porcelain and will not peel. The peeling is caused by

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