Ensure lighting procedure is followed carefully. All gas grill

turned on. Turn tank on slowly to allow pressure to equalize.
See lighting instructions.
Pipe must be sized according to installation code.
Pre-heat grill with main burners on high for 10 to 15 minutes.
Ensure sear plates are installed correctly. The archs without
slots should be located directly above the left and right
burners. When the sear plates are installed correctly, six of
the eight slots should be in valleys.
Pre-heat grill with main burners on high for 10 to 15 minutes.
Clean sear plates and drip pan regularly. Do not line base
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.
Close air shutter slightly according to combustion air
adjustment instructions.
Replace with heavy duty 'AAA' battery. Install with positive
terminal up.
Check that electrode wire is firmly pushed onto the terminal
on the back of the igniter.
One spark systems must use a one spark igniter.
Ensure that the collector box is tight, and the gap between the
electrode end and the collector box is between 1/8 - 3/16".
