Solution
Replace LP gas cylinder
Remove LP gas cylinder. Re-install correctly and tighten.
Replace cylinder if damaged. See "Leak Test" and "Connecting
Regulator to LP Gas Cylinder" sections.
Turn off regulator knob and remove LP gas cylinder. Once fire
is out and grill has cooled off, clean residual food particles and
excess grease from inside firebox area, grease cup, and other
surfaces.
If you can safely reach the regulator knob, turn it to the "OFF" po-
sition, then remove the LP gas cylinder. Once grill has cooled, clean
burner and Venturi tubes. See "How to Clean the Burner" section.
See re-assembly after cleaning in "Care and Maintenance".
Push regulator knob in and turn counterclockwise to the "HIGH"
position. Depress the igniter button until a loud click is heard.
Repeat until the burner lights.
1. Electrode tip is bent (making too large or small of a gap between
the electrode and burner). Bend electrode tip back to 3/16" gap
to burner. (Pg. 10)
2. Tighten electrode mounting screws.
3. Replace igniter wire/electrode assembly. (Call Customer Service
