Alternative Piping Methods To

Connect Appliance To Gas Supply

A TRAINED SERVICE TECHNICIAN OR GAS

APPLIANCE INSTALLER MUST MAKE THE GAS

SUPPLY CONNECTION. Leak testing of the

appliance shall be conducted by the installer

according to the instructions given.

Unless prohibited by local codes or ordinances, a new

A.G.A. -- Certified, flexible metal appliance connector may

be used to connect this appliance to its gas supply. The

connector must be no more than 5 feet in length. Per

figure 5, use appropriate flare union adapter at each end

of the flexible connector. If a flexible connector is used

assure that both the appliance pressure regulator and

manual shut-off valve are joined solidly to other

permanent hard piping (either gas supply or the appliance

manifold) so as to be physically stationary. See

illustrations below.

CAUTION:

Do not attempt to attach the flexible

connector directly to an external pipe thread.
Connection requires flare union adapters.

I M P O R T A N T

Apply a non-corrosive leak detection fluid to all joints and

fittings in the gas connection between the supply line

shut-off valve and the range. Include gas fittings and

joints in the range if connections were disturbed during

installation. Check for leaks! Bubbles appearing around

fittings and connections will indicate a leak. If a leak

appears, turn off supply line gas shut-off valve, tighten

connections, turn on the supply line gas shut off valve,

and retest for leaks. Never test for gas leaks with an open

flame.

Pressure Testing

The appliance must be isolated from the gas supply

piping system by closing its individual manual shut-off

valve during any pressure testing of the gas supply piping

system at test pressures equal to or less than 1/2 pounds

per square inch (3.5 kPa).
This appliance, as well as its individual shut-off valve,

must be disconnected from the gas supply piping system

during any pressure testing of the system at test

pressures in excess of 1/2 pounds per square inch (3.5

kPa).
When checking appliance regulator function, make certain

pressure of natural gas supply is between 6 and 14

inches of water column or, if converted for LP gas,

between 11 and 14 inches of water column.
