9. A boiler used for heating or seasonal loads or for stand-by service may have an extended period of non-use.
Special attention must be given so that neither waterside surfaces are allowed to deteriorate from corrosion.
10. There are two methods of storage - wet or dry. Your water consultant or feedwater treating company can
recommend the better method, depending upon circumstances in a particular installation. Section VII of the
ASME Code also contains information relating to laying up a boiler. Extended shutdown of the boiler and
restarting are as follows:
a. Turn off all power.
b. Enter boiler into dry storage.
c. Tag power switch(es) that energy is off and tank is in storage condition.
d. Remove tank from storage and turn power switch(es) on to start. Reset all controls and conduct start-up of
the boiler as discussed previously.
