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.
1) Burner tube
2) Tips occasionally flicker yellow
3) Light blue
4) Dark blue
If the flames do not appear to be uniform throughout the burner tube, follow the burner
cleaning procedures.
MAIN BURNER CLEANING PROCEDURE
Turn off the gas supply. Remove burners first (See section - Replacing Main Burners).
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 burner orifice (5). Use a Steel 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.
