Spider Stopper Guards
Your 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 5. This could result
in a fire in and around the air shutters, under the control
panel, causing serious damage to your barbecue.

MAINTENANCE
Inspection and Cleaning of the Spider
Stopper Guards
To inspect the Spider Stopper Guards, remove the control
panel and look to see if they have dust or dirt on their
outside surfaces. If they are dirty, brush off the outside
surface of the Spider Stopper Guards with a soft bristle
brush (an old toothbrush for example). Check that there
are no gaps in the Spider Stopper Guards’ seams or in
the fit around the burners or valves.
The Spider Stopper Guard is factory installed. It 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. Figure 6.
