What does the term "Disconnected boiler" mean?

The term "Disconnected boiler" refers specifically to a condition where all connections for fuel, water, steam, and electricity have been removed. This indicates that the boiler is not just turned off or under maintenance; it is no longer connected to any of the systems necessary for its functioning. This status ensures that the boiler is completely isolated from its operational environment, which is crucial for safety during maintenance or movement. When a boiler is in this state, it cannot inadvertently operate or pose any hazard related to utility services, making it an important operational consideration in maintenance and safety protocols.
