If the flames are mostly yellow or are noisy and lift off the burner ports, rotate the air
shutter to progressively reduce the amount of air entering the venturi.
Continue to
close the air shutter until the flame no longer lifts from the burner. For a sooty flame,
progressively open the air shutter until the flame burns cleanly.
Once adjusted to a stable flame that burns cleanly and does not lift, turn the grill control
knob to the OFF position. Tighten the lock screw. Re-light and confirm the adjustment is
good. Once confirmed, replace the radiant and burner tube, place the pin back into hole at
the back of the burner tube to secure the radiant and burner tube in place, then replace
the faceplate.
