represent all Genesis Gas Barbecue models, your
barbecue may differ from these illustrations.
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 of the
burner tubes. This blocks the normal gas flow, and can
cause the gas to flow back out of the air shutter.
Figure 1. This could result in a fire in and around the air
shutters, under the control panel, causing serious
damage to your barbecue. We have developed the
Weber Spider Stopper Guards to significantly
reduce the chance of this happening to your Weber
Genesis Gas Barbecue.
The Weber Spider Stopper Guard fits tightly around the
air shutter section of the burner tube and the valve,
thereby preventing spiders and other insects access to
the burner tubes through the air shutter openings.
