7.6Appliance Isolation during Gas Supply Piping Pressure Test

1.The appliance and its provided manual shutoff valve must be disconnected from the gas supply piping system during any pressure testing of that system at test pressures in excess of ½ PSI (3.5 kPa).

2.The appliance must be isolated from the gas supply piping system by closing its individual manual shutoff valve during any pressure testing of the gas supply piping system at test pressures equal to or less than ½ PSI (3.5 kPa).

3.The appliance and its gas connection must be leak-tested before placing it in operation.
