If the gas supply piping is to be tested at a test pressure in excess of 1/2 psig(3.45Kpa), the appliance and its
individual shut-off valve must be disconnected from the supply line. If the gas supply piping system is to be tested
at a pressure equal to or less than 1/2 psig(3.45Kpa), the individual shut-off valve must be closed during testing.

REGULATOR VENT CHECK
