Main Burner Cleaning Procedure

Turn off the gas supply. Remove the manifold. Look
inside each burner with a flashlight. Figure 7.

Clean the inside of the burners with a wire (a straightened
out coat hanger will work). Figure 8. 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.

CAUTION: Do not enlarge the burner ports when
cleaning.
