3.6.3 LONG TERM SHUT-DOWN (WEEKS)
To store the boiler in a corrosion-free situation there are three practical solutions:
1. Fullyoodtheboilertoexcludeasmuchairaspossible.
2. Drain the boiler completely.
Remove all hand hole and manhole doors.
Open all gas/oil side access doors.
3. As (2) but also introduce a form of convection heating to the gas/oil and water side.
A very effective solution is to install a small heater.

large thermal mass in the boiler will maintain the internal temperature to a point that the boiler
canbesimplyswitchedon(preferablyonlowre)andthenlefttoreachworkingtemperature/
pressure.
