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 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.
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.
