Maintenance - Weber Genesis Silver-A Owner's Manual

Weber Spider/Insect screens
Your Weber ® gas barbecue, like 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 deny spiders and insects access to the burner
(1)
tubes through the air shutter openings.
We recommend you inspect the Spider/Insect screens
at least once a year. (See Section "Maintenance".) Also
inspect and clean the Spider/Insect screens if any of
the following symptoms should 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.
Failure to correct the above symptoms may result in a
fire, which can cause serious bodily injury or death,
and cause damage to property.

DANGER
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 (such as an old
toothbrush).
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. When 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.
