The hose and regulator are connected in the following manner:
Slide back the collar of the quick disconnect on the tank valve. Push the male fitting of the regulator into the quick disconnect, and maintain pressure. Slide the collar closed. Figure 32 (a).

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: a soap and water solution and a rag or brush to apply it.
Note - Since some leaks test solutions, including soap and water, may be slightly corrosive, all connections should be rinsed with water after checking for leaks.
Make sure side burner is OFF. Remove valve control knob and screws. Remove porcelain top. Figure 33.
