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.

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

collector box is between 1/8" - 3/16" (3mm-
5mm). The gap can be adjusted by bending
the box in or out.
Close air shutter slightly - see previous
