GAS Line Connection, To Test Valve Pressures

Initial Installation

Gas Line Connection and Testing:

WARNING: Only persons licensed to work with gas piping may make the necessary gas connections to this appliance.

GAS LINE CONNECTION

•This stove is equipped with a certified flexible pipe located on the right side of the unit terminating in a ⅜” male NPT fitting. Consult your local authorities codes or the CAN/CGA B 149 (1 or 2) installation code in Canada, or in the USA gas installations follow either local codes or the current edition of the National Fuel Gas Code ANSI Z223.1.

•The efficiency rating of this appliance is a product thermal efficiency rating determined under continuous operating conditions and was determined independently of any installed system.

The appliance and its shutoff valves must be disconnected from the gas supply piping system during any pressure testing where the pressure exceeds ½ PSIG (3.45 KPa) or damage will occur to the valve.

The 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 ½ psig (3.45 KPa).

Always check for gas leaks with a soap and water solution after completing the required pressure test.

The pressure taps are located on the top right of the valve shown in Figure 42.

•Turn set screw 1 turn counter clockwise to loosen,

•Place 5/16” (8 mm) I.D. hose over pressure tap system.

•Check pressures using a manometer.

•When finished, release pressure, remove hose & tighten set screw.
