Main Burner Cleaning Procedure
Turn off the gas supply. Remove the manifold.
Look inside each burner 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
opening at the ends of the burners. Check and clean the
valve orifices 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.
