Some of the following are general requirements taken from the latest edition of the National Fuel Gas Code: ANSI Z 223.1/NFPA 54, or CAN/ CGA-B149.1, Natural Gas and Propane Installation Code for complete specifications. • This barbecue is designed to operate at 4.5 inches of water column pressure (.16241 psi). A manual shut-off valve must be installed outdoors, immediately ahead of the quick disconnect. • An additional manual shut-off valve indoors should be installed in the branch fuel line in an accessible location near the supply line • The quick disconnect connects to a 3/8 inch NPT thread from the gas source. The quick disconnect fitting is a hand-operated device that automatically shuts OFF the flow of gas from the source when the barbecue is disconnected • The quick disconnect fitting can be installed horizontally, or pointing downward. Installing the fitting with the open end pointing upward can result in collecting water and debris. • The dust covers (supplied plastic plugs) help keep the open ends of the quick disconnect fitting clean while disconnected. • Pipe compound should be used which is resistant to the action of natural gas when connections are made. • The outdoor connector must be firmly attached to rigid, permanent construction. ƽ WARNING: Do not route the 10 foot hose under a deck. The hose must be visible. Gas Line Piping • If the length of the line required does not exceed 50 feet, use a 5/8" O.D. tube.
