Steam Heater Shutdown Steps

  1. Dial down the thermostat so the fan is turned off.
  2. Make sure the main power supply is turned off at its source before disconnecting the power wiring to the heater.
  3. Turn off the main steam supply to the heater.
  4. Slowly close the ball valve supplying steam to the heater.
  5. Close the ball valve after the steam trap.
  6. Open the steam trap blow-down valve.
    Caution: If significant flashing occurs when draining to the floor, close the valve and wait for the condensate to cool.
  7. After the supply line has cooled, disconnect the steam supply connecting the heater.
  8. After the line has cooled, disconnect the condensate return piping from the facility’s return system.
  9. After the line has cooled, disconnect the condensate hose.
