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 fl ow, and can cause the gas to
fl ow back out of the combustion air opening. This could result in a fi re in and
around the combustion air openings, under the control panel, causing serious
damage to your barbecue.
The burner tube combustion air opening is fi tted with a stainless steel
screen(2) to prevent spiders and other insects access to the burner tubes
through the combustion air 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 fl ames appearing yellow
and lazy.
2) Barbecue does not reach temperature.
3) Barbecue heats unevenly.
4) One or more of the burners do not ignite.
ƽDANGER
Failure to correct the above mentioned symptoms may
result in a fi re, which can cause serious bodily injury or
death, and cause damage to property.
AnnnNNUAL 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.
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, please
contact the Customer Service Representative in your area using the contact
information on our web site. Log onto www.weber.com
