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 13.
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.
(See Section “Replacing the main burners”.)
Look inside each burner with a flashlight. Figure 14.
Clean the inside of the burners with a wire
(a straightened out coat hanger will work). Figure 15.
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.
