Step 1

Fittings &
Regulator
The grill and its individual shut-off valve must
be disconnected from the gas supply during
any pressure testing of the system at test
pressures in excess of 1/2 PSIG.
The grill must be isolated from the gas supply
system by closing its individual shut-off valve
during any pressure testing of the system at
test pressures equal to or less than 1/2 PSIG.
Check with local gas utility or with local codes
for instructions on installing gas supply lines.
Be sure to check on type and size of run and
how deep to bury the line. If the gas line is too
small, the grill will not function properly.
• Install a manual gas shut-off valve in an easily
accessible location.
• Use threading compound on non-flare
fittings only. Do not use threading compound
on the male end of the 1/2 NPT to 3/8 flare
adapter.
• Make connections as shown.
• Remove quick disconnect hose assembly from
manifold pipe.
• Leave flare fitting in the manifold pipe (1/2"
to 3/8" flare).
• Attach installer supplied gas line to end of
flare fitting on the manifold.
• Install regulator to gas line.
• Install 1/2" NPT close nipple to supplier
installed shut-off valve.
• Check to be sure the regulator arrow points
in the direction of gas flow, towards the grill
and away from the gas supply.
The installation of this grill must conform
with local codes or, in the absence of local
codes, with the National fuel gas code, ANSI
Z223 latest edition. Installation in Canada
must be in accordance with the Standard CAN
1-b149-1 and/or .2 (installation code for gas
burning appliances and equipment) and local
codes.
Operating pressure is 4" W.C.
Supply pressure should be 5" to 14" W.C. If
pressure is more than 14" W.C. a step down
regulator is required.
