Shutdown and preservation
Shutdown
Shutdown means shutting down the system via the cir-
cuit breaker at the control panel. The duration of the
shutdown determines the preservation measures
described in this chapter. A short-term shutdown is not recommended, as every
start-up process subjects the boiler to additional
stresses. For a period of up to 72 hours, for example
over a weekend, the boiler should be left to continue
operating.
