MAINTENANCE 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 4. This could result in a fire in and around the air shutters, under the control panel, causing serious damage to your barbecue. Venturi Air shutter Venturi fin Figure 4 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 5. Spider Stopper Guard We recommend that you inspect the Spider Stopper Guards at least once a year. 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. ƽ DANGER Failure to correct these symptoms may result in a fire which can cause serious bodily injury or death and cause damage to property. 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. Figure 5 9
