CLEANING THE MAIN BURNER
• To clean the gas ports of your main burners use a stiff bristle brush to brush the
openings.
• Refer to: Inspection and Cleaning of the Spider/Insect Screens for the removal
of the burner tube.
• You can now lift the burner tube out of the burner box and inspect inside with a
flashlight.
• Clean the inside of the burners with a wire (a straightened-out coat hanger will
work). Check and clean the air shutter openings at the ends of the burners.

the outside of the burners. This is to make sure that all burner ports are fully open.
