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 6. 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 7.

2.Barbecue does not reach temperature.

3.Barbecue heats unevenly.

4.One or more of the burners do not ignite.

mDANGER

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

Turn off the gas supply. Remove the manifold. (See Section “Replacing the main burners”.)

Look inside each burner with a flashlight. Figure 9.

Clean the inside of the burners with a wire (a straightened out coat hanger will work). Figure 10. 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.
