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
confirm 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 ANISI 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.
■ 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.
ƽ WARNING: Do not route the 12 foot hose under
a deck. The hose must be visible.
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 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
ƽ 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.
