with worn threads.

Prevention/Solution

• Replace ignitor.

• Replace knob.

• Inspect wire insulation and proper connection. Replace wires if 

insulation is broken.

• Use long-stem match (fireplace match).

• See “Match-Lighting” section of Use and Care.

• Check for gas in LP cylinder.

• Turn off control and tank knobs, wait 30 seconds, turn tank knob 

on slowly, light grill. If flames are still low, turn off control and 
tank knobs and disconnect regulator. Reconnect regulator, turn 
tank knob on slowly, light grill.

• Turn off control and tank knobs and disconnect regulator. 

Reconnect regulator, turn on tank knob slowly, light grill.

• Turn front of grill to face wind or increase flame height.

• Refill LP cylinder.

• Refer to “Sudden drop in gas flow” above.

• Clean burners and inside of grill/firebox.

• Trim fat from meat before grilling.

• Adjust (lower) temperature accordingly.

• Turn knobs to OFF. Turn gas off at LP cylinder. Leave lid in position 

and let fire burn out. After grill cools, remove and clean all parts.

cleaning section of Use and Care.

• The worn nozzles don’t have enough “bite” to engage the valve. 

Try a second LP dealer.
