Important Information about
Natural Gas & Gas Connections
What is Natural Gas?
Natural gas (NG) is a combustible, gaseous mixture
of simple hydrocarbon compounds, usually found in
deep underground reservoirs formed by porous rock.
It is a fossil fuel composed almost entirely of methane.
Natural gas is delivered by your local utility through an
underground pipeline system.
General Specifications
• Three burner grills are designed to operate at 7" of
water column pressure (0.2526 psi).
• Four burner grills are designed to operate at 4.5" of
water column pressure (0.16245 psi).
• The quick-disconnect fitting can be installed
horizontally or pointing downward, but never pointing
upward. Installing it with the open end pointing upward
can result in water and debris collecting in the quick-
disconnect fitting.
• The dust covers (plastic plugs supplied with your grill)
help keep the open ends of the quick-disconnect fitting
clean while disconnected.
Hose Requirements
• The grill is equipped with a model specific hose that
was attached during the manufacturing process. This
specific hose must be used for proper performance.
• If the hose becomes worn or damaged, contact the
Customer Service Representative in your area using
the contact information on our website.
Pressure Testing the Gas Supply
• Disconnect the gas grill when the gas supply is being
tested at high pressures. This appliance and its
individual shutoff valve must be disconnected from the
gas supply piping system during any pressure testing
of that system at test pressures in excess of 1/2 psig
(3.5 kPa).
• Turn off the gas grill when the gas supply is being
tested at low pressures. This appliance must be
isolated from the gas supply piping system by closing
its individual manual shutoff valve during any pressure
testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig (3.5 kPa).
