General Maintenance Weber Spider /Insect screens 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 Venturi(1). This blocks the normal gas flow, and can cause the gas to flow back out of the air shutter. This could result in a fire in and around the air shutters, under the control panel, causing serious damage to your barbecue. (1) The burner tube air shutter is fitted with a stainless steel screen(1) to prevent spiders and other insects access to the burner tubes through the air shutter openings. (1) We recommend that you inspect the Spider/Insect screens at least once a year. (See Section "Annual Maintenance".) Also inspect and clean the the Spider/Insect screens 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 the above mentioned symptoms may result in a fire, which can cause serious bodily injury or death, and cause damage to property.
