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.

2.Barbecue does not reach temperature.

3.Barbecue heats unevenly.

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

Main Burner Cleaning Procedure

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.
