Figure 25).
2.
Pressurize supply piping system by
either using compressed air or open-
ing main gas valve located on or near
gas meter.

Pressure Testing Gas Supply
Piping System
Test Pressures In Excess Of 1/2 PSIG
(3.5 kPa)
1.
Disconnect appliance with its appliance
main gas valve (control valve) and equip-
ment shutoff valve from gas supply pip-
ing system. Pressures in excess of 1/2 psig
will damage heater regulator.
2.
Cap off open end of gas pipe where
equipment shutoff valve was connected.
3.
Pressurize supply piping system by
either using compressed air or open-
ing main gas valve located on or near
