INSTALL GAS SUPPLY (CART INSTALLATIONS ONLY)

General Specifications for Piping

Note - Contact your local municipality for building codes regulating outdoor gas barbecue installations. In absence of Local Codes, you must conform to the latest edition of ANSI Z223.1. WE RECOMMEND THAT THIS INSTALLATION BE DONE BY A PROFESSIONAL.

Some of the following are general requirements taken from ANSI Z223.1, for gas supply installations. Refer to ANSI Z223.1 latest edition for complete specifications.

■This barbecue is designed to operate at 4.5 inches of water column pressure (.2526 psi). Use only the regulator with the cooking module.

■A manual shut-off valve must be installed outdoors, immediately ahead of the quick disconnect.

CAUTION: If young children are in the area, a locking valve should be considered.

■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.

WARNING: Do not route the 12 foot hose under a deck.The hose must be visible.

Gas line piping

■If the length of line required does not exceed 50 feet, use a 5/8" O.D. tube. One size larger should be used for lengths greater than 50 feet.

■Gas piping may be copper tubing, type K or L; polyethylene plastic tube, with a minimum wall thickness of .062 inch; or standard weight (schedule 40) steel or wrought iron pipe.

■Copper tubing must be tin-lined if the gas contains more than 0.3 grams of hydrogen sulfide per 100 cubic feet of gas.

■Plastic tubing is suitable only for outdoor, underground use.

■Gas piping in contact with earth, or any other material which may corrode the piping, must be protected against corrosion in an approved manner.

■Underground piping must have a minimum of 18" cover.

Test connections

All connections and joints must be thoroughly tested for leaks in accordance with local codes and all listed procedures in the latest edition of ANSI Z223.1.

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 gas leaks. This will result in a fire or explosion which can cause serious bodily injury or death, and damage to property.
