ATTENTION: The conversion shall be carried out in accordance with the requirements of the provincial authories having

jurisdicon and in accordance with the requirements of the ANSI Z223.1 installaon code.

This replace is manufactured for use with natural gas. Follow the instrucons included with the conversion kit if con-

verng to propane.

4.2 Gas Line Installaon

CAUTION: Installaon of the gas line must only be done by a qualied person in accordance with local building codes, if

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.
