Main Burner Cleaning Procedure
Turn off the gas supply. Remove the manifold.
Look inside each burner with a torch.
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 orifices at the base of the
valves. Use a brass bristle brush to clean outside of
burners. This is to make sure all the burner ports are
fully open.
ƽ CAUTION: Do not enlarge the burner ports
when cleaning.
