Install gas supply

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 7 inches of

water column pressure (.2526 psi).

■ 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’ hose under a

deck. The hose must be visible.

Typical natural gas supply installation. Figure 10.

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.
