3. IMPORTANT Ensure vacuum breakers are installed on the steam system risers If vacuum breakers that open to the atmosphere at zero psig are not installed the system can develop a negative pressure and pull steam back into the radiators on resumption of steam Refer to Fig 12 for installing the one pipe steam radiator adapter assembly Single Pipe Steam Systems T100 V2043H with vent operation to provide temperature control for a formerly uncontrolled single pipe steam system follows 1 The boiler is off zero steam pressure radiators are filled with air the vent is open 2 The T100 calls for heat opening the valve 3 At the command of an external controller such as a representative zone thermostat or a timer controlled by outside temperature the boiler cycles on and begins delivering steam to the system 4 Steam enters the radiator forcing air through the open V2042H and out through the vent 5 Once the air is exhausted the steam heats the thermostatic element of the vent causing it to close 6 The steam cools forming condensation Condensation flows out of the radiator making room for more steam to enter 7 The T100 is eventually satisfied temperature equals the setpoint and it closes the V2042H 8 The air in the system introduced by the vacuum breakers begins to fill the radiator The air in the radiator prevents steam from coming in and the radiator cools 9 The boiler cycles off by command of com
