Gas line piping
■ 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.
■ 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.

General Specifications for Piping
Note - Contact your local municipality for building
codes regulating outdoor gas barbecue installations.
In absence of Local Codes, you must conform 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 ANSI Z223.1, for gas supply installations. Refer to
ANSI 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.
ƽWARNING: Do not route the 12’ hose under a deck.
The hose must be visible.
