Cooking After a Period of Nonuse You can adjust the FRONT, CENTER and BACK burners as desired. The control settings High (H), Medium (M), Low (L), or Off (O) are described in your Weber cookbook. The cookbook uses these notations to describe the settings of the FRONT, CENTER, and BACK burners. For example, to sear steaks you would use (HHH) (all burners at high). Then to complete cooking you would use (MOM) (FRONT at medium, CENTER off, and BACK at medium).
If a leak persists after retightening the fitting, turn OFF the gas. DO NOT OPERATE THE BARBECUE. Contact your dealer. Annual Maintenance After a period of nonuse we recommend that you perform the following maintenance procedures for your safety. c) Side burner hose to side burner connection. Figure 5 (c). WARNING: Check gas supply line before each use of barbecue for nicks or cracking. If the gas supply line is found to be damaged in any way, do not use the barbecue.
General Maintenance Main Burner Flame Pattern Weber Spider Stopper Guards The Weber Gas Barbecue burners have been factory set for the correct air and gas mixture. The correct flame pattern is shown in Figure 8. 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.
d) Unlatch the Spider Stopper Guards and remove. Figure 11. h) Lift and twist the burner assembly slightly, to separate the crossover tube from the burners. Figure 14. Remove the burners from the cooking box. Crossover tube Figure 14 Figure 11 e) Disconnect gas supply line and side burner. i) f) CAUTION: The burner openings must be positioned properly over the valve orifices. Figure 15 (a). Remove the manifold bracket and unscrew the two wing nuts that hold the manifold to the cooking box.
j) Crossover Ignition System Operations Reinstall the Spider Stopper Guards. Slightly rotate the Spider Stopper Guards so that the seams are in line with the Venturi fins. There should be no gaps in the seams or in the fit around the burners and valves. Figure 16. If the Crossover Ignition System fails to ignite the Front burner, light the Front burner with a match. If the Front burner lights with a match, then check the Crossover Ignition System.
