Look inside each burner with a fl ashlight.
Clean the inside of the burners with a wire (a straightened-out coat hanger
will work). Check and clean the air shutter opening at the ends of the
burners. Check and clean the valve orifi ces at the base of the valves. Use
a Steel bristle brush to clean outside of burners. This is to make sure all the
burner ports are fully open.
CAUTION: Do not enlarge the burner ports when
