ADJUST GRILL BURNER
AIR SHUTTER
The air shutters for the grill burner may need to be
adjusted to get better flame appearance and ignition. The
air shutters for the grill burner are located on the bottom
of the grill burner. To access the air shutters, remove the
grill grate, and then the grill burner. Loosen the screw and
slide the air shutter backward or forward to increase or
decrease the size of the air opening. Re-tighten the screw.

CHECK IGNITION
Connect electrical supply cord.
Turn on the gas; check for leaks using a liquid leak
detector at all joints in the system.
WARNING:
DO NOT USE A FLAME
TO CHECK FOR GAS LEAKS.
Push in one control knob and
turn to the LITE position. The
igniter will spark and the burner
will light. The first test may
require some time while air is
flushed out of the gas line. After
ignition, turn the control knob
to the HI position and wait until the flame settles.
Check to determine if your burner flames are
normal. If burner flames look like A, turn off the
burner and make sure all parts are assembled
correctly. Reassemble and check.
Normal burner flames should look like B or C,
depending on the type of gas you use. With LP gas,
some yellow tipping on outer cones is normal.
Turn the knob to OFF.
Repeat the procedure for each burner.
