Natural Gas Connection
Natural Gas Model only:
Connecting Natural Gas To Your Grill
Check all connections for Natural Gas Leaks
Never
test for leaks with an open flame. Prior to first use
and at the beginning of each season, you must check
for gas leaks. Follow these three steps:
Make a soap solution by mixing one part liquid
detergent and one part water.
Turn the grill Control Knobs to their full OFF
positions. Next, turn the gas ON at the source.
Apply the soap solution to all gas connections
indicated by the arrows. See
Fig.3
. If bubbles
appear in the soap solution the connections are
not properly sealed. Check each fitting and tighten
or repair as necessary.

Your natural gas grill is designed for use with
natural gas (NG) only. The gas pressure Regu-
lator supplied with this appliance
must
be in-
stalled and used on your grill. The unit and
Regulator are set to operate with an outlet
pressure of 4" W.C.
Install a Shutoff Valve at the gas supply source
outdoors at a point after the gas pipe exits the
outside wall and before the quick-disconnect hose.
Or install it at the point before the gas line piping
enters the ground. See
Fig. 2
.
Pipe sealing compound or pipe thread tape resis-
tant to the action of natural gas must be used on all
male pipe thread connections.
Disconnect your gas grill from fuel source when the
gas supply is being tested at high pressures. This
gas grill and its individual shutoff valve must be
disconnected from the gas supply pipe system
during any pressure testing of that system at pres-
sure in excess of 1/2 psi (3.5kpa).
Turn off your gas grill when the gas supply is being
tested at low pressures. The grill must be isolated
from the gas supply pipe system by closing its
individual manual shutoff valve during any pres-
sure testing of the gas supply pipe system at
pressures equal to or less than 1/2 psi (3.5kpa).
Natural Gas Safety Instructions
Connect the Swivel nut of the 12' Natural Gas
Hose to the horizontal fitting of NG Regulator
as shown in
Fig.1
. Connect the other hose end
(male plug) to the gas supply line from your
home. Read and follow the "Natural Gas Safety
Instructions" below.

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 must be copper tubing, type K or L;
polyethylene plastic tube, with a minimum wall
thickness of 0.62 inch; or standard weight (sched-
ule 40) steel or wrought iron pipe.
Copper tubing must be tin-lined if the gas con-
tains more than 0.3 grams of hydrogen sulfide per
100 cubic feet of gas.
Plastic tubing is suitable only for outdoor, under-
ground use.
Gas piping in contact with earth, or any other
material which may corrode the piping, must be
protected against corrosion in an approved man-
ner.
Underground piping must have a minimum of 18'
cover.
