Figure 17 (a) (b) Natural Gas Supply Pipe Pipe fitting end of 3/8-inch Flare Fitting Flare fitting end of 3/8-inch Flare Fitting Barbecue gas Apply pipe sealant here supply line 19 Step 11 Check all valves are off You will need: one burner control knob. (Valves are shipped in the OFF position, but you should check to be sure.) Put the knob on each valve. Check by pushing down and turning clockwise. If they do not turn they are off. Proceed to the next step. Figure 18. Figure 18 Step 12 Install side burner You will need: side burner assembly, burner grate, and manifold bracket. mWARNING: Make sure gas supply is OFF. Slide the side burner assembly into the open end of the right frame. Route the side burner hose around the tank panel so it will not interfere with scale indicator rod. The side burner hose is connected in the following manner: Slide back the collar of the quick disconnect on the manifold. Push the male fitting of the side burner hose into the quick disconnect, and maintain pressure. Slide the collar closed. Figure 19a. Figure 19b shows the quick disconnect engaged.Install burner grate. Check to be sure the side burner valve is OFF. Push side burner control knob down and turn clockwise. Figure 19. Manifold side view Male fitting of side burner a) Quick disconnect engaged Side burner hose b) Manifold side view Figure 19 20 Slide the side burner assembly into the open end of the right frame. Route the side burner hose so that it parallels the front of the barbecue. Loop the hose so that it reaches the side burner connection. Attach hose. Figure 20. Install burner grate. Check to be sure the side burner valve is OFF. Push side burner control knob down and turn clockwise. Figure 20. Figure 20 Step 13 Install manifold bracket You will need: manifold bracket. Hook the bracket onto the manifold at the center burner valve. Figure 21. Place your hand underneath the bracket. Lift the bracket, manifold and cooking box slightly as a unit and hook onto the frame brace. Figure 21 (a). Frame brace Manifold bracket (a) Figure 21 View from below cooking box Step 14 Purge air from gas lines You will need: one burner control knob. m DANGER Be sure there are no sparks or open flames in the area while purging. This can cause fire, explosion or serious bodily injury. It is necessary to bleed the air out of newly installed gas lines. Turn gas supply ON at the source. Put on the front burner control knob. Push the front burner control knob down and turn to HI. When you start to smell gas, turn front burner control knob to OFF. Figure 22. Figure 22 21 Step 15 Check for gas leaks m DANGER Do not use an open flame to check for gas leaks. Be sure there are no sparks or open flames in the area while you check for leaks. This will result in a fire or explosion which can cause serious bodily injury or death and damage to property. mWARNING: You should check for gas leaks every time you disconnect and reconnect a gas fitting. Note - All factory made connections have been thoroughly checked for gas leaks.The burners have been flame tested.As a safety precaution you should recheck all fittings for leaks before using your Weber Gas Barbecue.Shipping and handling may have loosened or damaged a gas fitting. mWARNING: Perform these leak checks even if your barbecue was dealer or store assembled. You will need: soap and water solution and a rag or brush to apply it. Make sure side burner is OFF. Remove valve control knob and screws. Remove porcelain top. Figure 23. Figure 23 To perform leak checks: Turn ON gas supply at the source. Figure 24. Gas supply shut off at the house Figure 24 mWARNING: Do not ignite burners while leak checking. Check for leaks by wetting the connections with the soap and water solution and watching for bubbles. If bubbles form or if a bubble grows there is a leak. Note - Since some leak test solutions, including soap and water, may be slightly corrosive, all connections should be rinsed with water after checking for leaks. Check: a) Gas supply line to manifold connection. Figure 25 (a). b) Manifold to side burner hose connection. Figure 25 (b). mWARNING: If there is a leak at connection (a) or (b), retighten the fitting with a wrench and recheck for leaks with soap and water solution. If a leak persists after retightening the fitting, turn OFF the gas. DO NOT OPERATE THE BARBECUE. Contact your dealer. c) Side burner hose to side burner connection. Figure 25 (c). d) Valves to manifold connections. Figure 25 (d). mWARNING: If there is a leak at connections (c) or (d), turn OFF the...
