TYPICAL NATURAL GAS SUPPLY INSTALLATION
We recommend that this installation be done by a LICENSED professional.
GENERAL SPECIFICATIONS FOR PIPING
Note - Contact your local municipality for building codes regulating outdoor gas grill
installations. In absence of Local Codes, you must conform to the latest edition of
National Fuel Gas Code ANSI Z223.1/NFPA54.
•
This grill is designed to operate at 4.5 inches of water column pressure.
•
A manual shut-off valve must be installed outdoors, and be accessible, not in the
"built-in" structure. An additional manual shut-off valve indoors should be installed
in the branch fuel line in an accessible location near the supply line.
CAUTION: If young children are in the area, a
locking valve should be considered.
•
Pipe compound should be used which is resistant to the action of liquid propane
gas when gas connections are made.
•
The gas connections must be firmly attached to a rigid, permanent construction.
Note: The information provided in this manual is general for typical installations. We
cannot cover all possible installation ideas. We recommend, prior to installation, that you
contact your municipality for local building codes and your local fire department for
installation verification.
If you have any questions, contact Customer Service at 1-800-446-1071.

GAS LINE PIPING
•
Refer to the piping chart at the bottom of previous page.
•
The corrugated gas line from the manifold is 58 inches (1,473.2 mm) long. Do not
extend the gas line.
•
We have provided the means to make an SAE 45° flare connection. Do not use
pipe sealant on this connection.
•
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. Refer to piping chart.
•
Gas piping may be copper tubing, type K or L; polyethylene plastic tube, with a
minimum wall thickness of .062 inch (1.57 mm); 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.
