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 PROFESSIONAL.
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 7" of water column pressure (.2526 psi).
• A manual shut-off valve must be installed outdoors, immediately ahead of the quick
• 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" 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 grill 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
• 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.
m WARNING: Do not route the ten foot hose under a deck. The
hose must be visible.
Gas Line Piping
• For the correct size and length of gas line piping refer 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.
• 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
• 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.
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.
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
This is a typical installation of a Weber
