WEBER ® SPIDER /INSECT SCREENS
Y our 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.
ƽ DANGER
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.
