Main Burner Flame Pattern
The Weber Gas Barbecue burners have been factory set
for the correct air and gas mixture. The correct flame
pattern is shown in Figure 7.
If the flames do not appear to be uniform the length of the
burner tube, follow the burner cleaning procedures.
Main Burner Cleaning Procedure
Turn off the gas supply. Remove the manifold.
Look inside each burner with a flashlight. Figure 8.
Clean the inside of the burners with a wire (a straightened
out coat hanger will work). Figure 9. 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.
ƽCAUTION: Do not enlarge the burner ports when
cleaning.
