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 the manifold.
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 valves. 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.

General Maintenance
Weber Spider Stopper™ Guards
Your Weber Gas Barbecue, as well as any outdoor gas
appliance, is a target for spiders and other insects. They
can nest in the venturi section (Venturi(1), air shutter(2),
venturi fin(3) ) of the burner tubes. This blocks the normal
gas flow, and can cause the gas to flow back out of the air
shutter. This could result in a fire in and around the air
shutters, under the control panel, causing serious damage
to your barbecue.
The Weber Spider Stopper™ Guard(1) is factory installed.
It fits tightly around the air shutter section of the burner
tube and the valve, thereby preventing spiders and other
insects access to the burner tubes through the air shutter
openings.
We recommend that you inspect the Weber Spider
Stopper™ Guards at least once a year. (See Section
“Annual Maintenance”.) Also inspect and clean the
Spider Stopper Guards if any of the following symp-
toms should ever occur:
1) The smell of gas in conjunction with the burner flames
appearing yellow and lazy.
2) Barbecue does not reach temperature.
3) Barbecue heats unevenly.
4) One or more of the burners do not ignite.
DANGER
Failure to correct the above mentioned symptoms may
result in a fire, which can cause serious bodily injury
or death, and cause damage to property.

Annual Maintenance
Inspection and Cleaning of the Weber Spider
Stopper™ Guards
To inspect the Spider Stopper Guards, remove the control
panel and look to see if they have dust or dirt on their
outside surfaces. If they are dirty, brush off the outside
surface of the Spider Stopper Guards with a soft bristle
brush (an old toothbrush for example). Check that there
are no gaps in the Spider Stopper Guards’ seams or in
the fit around the burners or valves. (See Section
“General Maintenance.”)
