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 counter clockwise 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
