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

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 12.

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.
If the flames do not appear to be uniform the length of the burner tube, follow the burner cleaning procedures.
Main Burner Cleaning Procedure
Turn off the gas supply. Remove the manifold. (See Section “Replacing the main burners”.)
Look inside each burner with a flashlight. Figure 14.
Figure 14
Clean the inside of the burners with a wire
(a straightened out coat hanger will work). Figure 15 Check and clean the air shutter opening at the ends of the burners. Check and clean the valve orifices at the base of the valves. Use a brass bristle brush to clean outside of burners. This is to make sure all the burner ports are fully open.
Figure 15
CAUTION: Do not enlarge the burner ports when cleaning.
