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 the
National Fuel Gas Code: ANSI Z 223.1/NFPA 54, or CAN/CGA-B149.1, Natural Gas and
Propane Installation Code. WE RECOMMEND THAT THIS INSTALLATION BE DONE BY A

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 grill is designed to operate at 4.5" of water column pressure (.163 psi).
• A manual shut-off valve must be installed outdoors, and be accessible, not in the
“built-in” structure (1).
• An additional manual shut-off valve indoors should be installed in the branch fuel line
in an accessible location near the supply line.
• The dust covers (supplied plastic plugs) help keep the open ends of the quick
disconnect fitting clean while disconnected.
• Pipe compound that is resistant to the action of natural gas should be used when
connections are made.
• The outdoor connector must be firmly attached to rigid, permanent construction (2).
Gas Line Piping
• If the length of the 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"; 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 the National Fuel Gas Code:
ANSI Z 223.1/NFPA 54, or CAN/CGA-B149.1.

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.
