They can nest in the venturi section of the burner tubes. This blocks the normal gas flow, and can cause the gas to flow back out of the air shutter. Figure 4. This could result in a fire in and around the air shutters, under the control panel, causing serious damage to your barbecue.

Your
Weber
Genesis
Gas
Barbecue,
as
well
as
any
outdoor
gas appliance, is
a
target
for spiders
and
other
insects.
They
can nest
in
the
venturi
section
of
the
burner
tubes. This
blocks
the
normal
gas
flow,
and
can
cause the
gas
to
flow
back
out
of the air
shutter.
Figure
4. This could
result
in
a
fire in
and around the air
shutters,
under the
control
panel,
causing serious
damage to
your
barbecue.
