Liquid Propane Cylinder requirements • Replacement LP cylinders supplied by Weber satisfy the above requirements. Check to be sure other cylinders have a D.O.T. certification(1), and date tested(2) is within five years. Your LP gas supplier can do this for you. If you have questions about spare LP cylinders contact the Customer Service Representative in your region using the contact information sheet provided with your manual. (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. DOT 4BA240 00/01 (2) • All LP tank supply systems must include a collar to protect the cylinder valve. • The LP cylinder must be a 20-lb. size (181⁄4 inches high, 121⁄4 inches in diameter). • The LP cylinder must be constructed and marked in accordance with the specifications for LP gas cylinders of the U.S. Department of Transportation (D.O.T.). We recommend that you inspect the Spider/Insect screens at least once a year. Also inspect and clean 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 these symptoms may result in a fire which can cause serious bodily injury or death and cause damage to property. GENERAL MAINTENANCE Spider/Insect screens Your 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) of the burner tubes. This blocks the normal gas flow, and can cause the gas to flow back out of the air shutter. Figure 5. This could result in a fire in and around the air shutters, under the control panel, causing serious damage to your barbecue. (1) Inspection and cleaning of the Spider/Insect screens To inspect the spider/insect screens, remove the control panel. If there is dust or dirt on the screens, remove the burners for cleaning the screens. Refer to Maintenance, Replacing Main Burners. Brush the spider/inspect screens, lightly, with a soft bristle brush (i.e. an old toothbrush). ƽ Caution: Do not clean the spider/insect screens with hard or sharp tools. Do not dislodge the spider/insect screens or enlarge the screen openings. Lightly tap the burner to get debris and dirt out of the burner tube. Once the spider/insect screens and burners are clean replace the burners. If the spider/insect screen becomes damaged or cannot be cleaned, call Weber-Stephen Products Customer Service for replacement parts. 13
