Figure 49: Fully Labeled Gas Valve.

The appliance and its shutoff 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 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 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 left side of the valve

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.
