2.17 CLEANING STEAM LINES AND PRESSURE VESSELS
 Duringtherstweekofboileroperation,cleanalloilanddirtfromtheboiler,thesteamlineand
condensate return line.
(a) Disconnect the condensate return pipe adjacent to the condensate return tank.
 (b) Directthereturnstoaoordrainorothersafedischargepointandmakesafe.
 (c) Leaveinthispositionforoneweektoallowallimpuritiestoushthrough.
(d) Drain the boiler completely each day.
 (e) Aftertheweekiscompleted,drainandushthecondensatereturntank,removingallinstallation
sediment. Reconnect the condensate return pipe to the condensate return tank.
2.16 COMMISSIONING THE BOILER - continued
(n) Adjust the steam pressure control to suit the boiler application. It should be borne in mind that
  boileraredesignedtooperatemostefcientlyattheirmaximumoperatingtemperature.When
boilers are to be operated below a pressure of 80 psi (5.5 bar) consideration should be given to
  thettingofapressurereducingset(seeSection2.8-SteamSafetyValves).
If the pressure control is tted with a differential scale:
(see OEM literature in section 5)
(i) Set the main scale pressure to the pressure
indicated on the boiler data plate.
(ii) Set the differential scale to it's minimum pressure.
  Ifthepressurecontrolhasaxeddifferential,
e.g. no adjustable differential scale, set the main
scale to the maximum pressure required.
Note: When boilers are tted with a sequence control:
(i) Set the main scale and differential scale as above.
(ii) Set the set-back pressure control to the required
set-back pressure.
