INSTALLATION
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 pressures 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 counterclockvwse wth a 1/8" wide fiat screwdriver.

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 v\^hin 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 snua. but do not over tighten
