any. If not, follow ANSI 223.1. Commonwealth of Massachuses installaons must be done by a licensed plumber or gas

er.

NOTE: The appliance and its individual shuto valve must be disconnected from the gas supply piping system during any

pressure tesng of that system at pressures in excess of ½ psi (3.5 kPa). For test pressures equal to or less than ½ psi (3.5

kPa), the appliance must be isolated from the gas supply piping system by closing its individual manual shut-o valve.

• A listed (and Commonwealth of Massachuses approved) ½” (13mm) tee handle manual shut-o valve and exible

gas connector are to be connected to the ½”(13mm) control valve inlet. If substung for these components, please

consult local codes for compliance.

• This replace is equipped with a 3/8” (10mm) x 18” (457mm) long exible gas connector and manual shut-o valve.

• The gas line should be run to the point of connecon where the shut-o valve and exible gas line will connect. See

Figure 2.1, Appliance Dimensions on page 9.
