Test Pressures In Excess Of 1/2 PSIG
1. Disconnect heater and its individual
manual shutoff valve from gas supply
piping system. Pressures in excess of
1/2 psig will damage heater regulator.
2. Cap off open end of gas pipe where
manual shutoff valve was connected.
3. Pressurize supply piping system by ei-
ther using compressed air or opening
main gas valve located on or near gas
meter.
