DANGER
WARNING
Note: Contact your local city inspection depart-
ment for building codes regarding the installation of
Natural Gas connection and outdoor gas appliances.
In the absence of Local Codes, you must conform to
the latest edition of ANSI Z223.1.
WE RECOMMEND NATURAL GAS PIPING
INSTALLATION BE DONE BY A PROFESSIONAL.
1. This grill is designed to operate at 7 inches water column
pressure ( .2526 psi ).
2. A manual shut-off valve must be installed outdoors, im-
mediately ahead of the quick disconnect.
3. An additional manual shut-off valve indoors should be
installed in the branch fuel line in an accessible location
near the supply line.
4. The quick disconnect connects to a 3/8 inch NPT thread
from the gas source. The quick disconnect fi tting is a
hand-operated device that automatically shuts off the fl ow
of gas from the source when the grill is disconnected.
5. The quick disconnect fi tting can be installed horizontally,
or pointing downward. Installing the fi tting with the open
end pointing upward can result in collecting water and
debris.
6. The dust covers ( supplied plastic plugs ) help keep the
open ends of the quick disconnect fi tting clean while
disconnected.
7. Pipe compound should be used which is resistant to the
action of natural gas when connections are fi rst made.
8. The outdoor connector must be fi rmly attached to rigid,
permanent foundation.
Test All Pipe Fitting 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 Specifi cations For Piping
Do not route the natural gas hose under a deck or patio.
The hose must be visible.
Gas Line Piping
1. If the length of the line required does not exceed 50 feet,
use 5/8 inch O.D. tube. One size larger should be used
for lengths greater than 50 feet.
2. Gas piping may be copper tubing, type K or L polyeth-
ylene plastic tube, with minimum wall thickness of .062
inch, or standard weight ( schedule 40 ) steel or wrought
iron.
3. 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.
4. Plastic tubing is suitable only for outdoor underground
use.
5. Gas piping in contact with earth, or any other material
which my corrode the piping, must be protected against
corrosion in an approved manner.

ground cover.
Installing Natural Gas Connection To Grill
