General Maintenance

Weber Spider Stopper Guards
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.

Air shutter
The Weber 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 5.

We recommend that you inspect the Weber Spider
Stopper Guards at least once a year. (See section
"Annual Maintenance".) Also inspect and clean the
Spider Stopper Guards if any of the following
symptoms should ever 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.
DANGER
Failure to correct these symptoms may
result in a fire which can cause serious
bodily injury or death and cause damage
to property.

Main Burner Cleaning Procedure

section with a brass wire brush. This is to make sure all
the burner ports are fully open.
CAUTION: Do not enlarge the burner ports when
