Waterford Appliances T25-NG, T25-LP GAS Connection, GAS Pipe Pressure Testing, Valve Description

INSTALLATION

GAS CONNECTION

The gas connection is a 3/8" NPT 90o elbow. The gas line can be rigid pipe or to make installation easier, use a listed flexible connector and/or copper tubing if allowed by local codes. Since some municipalities have additional local codes it is always best to consult with your local authorities and the CAN/CGA B149 installation codes.

For USA installations follow local codes and/or the current National Fuel Gas Code, ANSI Z223.1.

The gas control valve is under the unit, behind the drop down door and control panel. The gas inlet is located on the left side of the unit (viewed from the front). The inlet fitting is a 3/8" male flare.

When using copper or flex connectors use only approved fittings. Always provide a union so that gas lines can be easily disconnected for burner and/or valve servicing. Flare nuts for copper lines and flex connectors are usually considered to meet this requirement.

Important: Always check for gas leaks with a soap and water solu- tion or gas leak detector. Do not use open flame for leak testing.

Note: Prior to any pressure testing of the gas supply piping system that exceeds test pressures of 1/2 psig, this appliance must be disconnect- ed from the piping system. If test pressures equal to or less than 1/2 psig are used then this appliance must be isolated from the piping system by closing its individual man- ual shut-off valve during the testing.

Note: Never use plastic pipe. Check to confirm whether your local codes allow copper tubing or galvanized pipe.

GAS PIPE

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 psig. (3.45 kPa). Disconnect piping from valve at pres- sures over 1/2 psig. The manifold pressure is controlled by a regulator built into the gas control, and should be checked at the pressure test point.

Note: To properly check gas pressure, both inlet and manifold pressures should be checked using the valve pressure ports on the valve.

1)Make sure the valve is in the "OFF" position.

2)Loosen the "IN" and/or "OUT" pressure tap(s), turning counterclockwise with a 1/ 8" wide flat screwdriver.

3)Attach manometer to "IN" and/or "OUT" pressure tap(s) using a 5/16" ID hose.

4)Light the pilot and turn the valve to "ON" position. Read manometer.

5)The pressure check should be carried out with the unit burning and the setting should be within the limits specified on the safety label.

6)When finished reading manometer, turn off the gas valve, disconnect the hose and tighten the screw (clockwise) with a 1/8" flat screwdriver. Note: Screw should be snug, but do not over tighten
