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.
ƽCAUTION: Do not enlarge the burner ports when
cleaning.

Weber ® Spider /Insect screens
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(1) 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 burner tube air shutter is fitted with a stainless steel
screen(1) to prevent spiders and other insects access to
the burner tubes through the air shutter openings.
We recommend that you inspect the Spider/Insect
screens at least once a year. (See Section “Annual
Maintenance”.) Also inspect and clean the the Spider/
Insect screens if any of the following symptoms
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.
ƽ 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 Spider/Insect screens
To inspect the spider/insect screens, remove the control
panel. If there is dust or dirt on the screens, remove the
burners for cleaning the screens. Refer to Maintenance,
Replacing Main Burners. Brush the spider/inspect
screens, lightly, with a soft bristle brush (i.e. an old
toothbrush).
ƽ CAUTION: Do not clean the spider/insect screens
with hard or sharp tools. Do not dislodge the
spider/insect screens or enlarge the screen
openings.
Lightly tap the burner to get debris and dirt out of the
burner tube. Once the spider/insect screens and burners
are clean replace the burners.
If the spider/insect screen becomes damaged or cannot be
cleaned, call Weber-Stephen Products Customer Service
for replacement parts.
