TYPICAL BULK PROPANE GAS SUPPLY INSTALLATION
We recommend that this installation be done by a LICENSED
professional.
General Specifi cations 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 the National Fuel Gas Code ANSI Z223.1/
NFPA 54.
•
This grill is designed to operate at 10.5 inches of water column
pressure. An LP in line regulator may be necessary for this pressure.
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 fi rmly attached to 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 fi re department for installation
verifi cation.
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 long. Do not
extend the gas line.
•
We have provided the means to make an SAE 45° fl are 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; 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 sulfi de 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.
