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

3) Light 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 the manifold.
Look inside each burner with a torch.
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 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.
