Gas Line Connection, To Test Valve Pressures

Initial Installation

QUALIFIED INSTALLERS ONLY

GAS LINE CONNECTION:

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

Gas Line Connection:

•This fireplace is equipped with a certified flexible pipe located on the right side of the unit, terminating in a 3⁄8” male NPT fitting. Consult the local authorities for local codes or use the CAN/CGA B149 (1 or 2) installation code in Canada. In the US, gas installations follow either local codes or the current edition of the National Fuel Gas Code ANSI Z223.1.

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

Figure 26: Fully Labeled Gas Valve.

The appliance and its’ shut-off valves must be disconnected from the gas supply piping system during any pressure testing where the pressure exceeds 1⁄2 psig (3.45 KPa) or the valve will be damaged.

The unit 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 pressures equal to or less than 1⁄2 psig (3.45 KPa).

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

TO TEST VALVE PRESSURES:

The pressure taps are located on the top right of the valve.

•Turn set screw 1 turn counterclockwise to loosen.

•Place 5/16 in (8 mm) I.D. hose over the pressure taps.

•Check pressures using a manometer.

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