When taking a boiler out of service, what is one thing you do NOT do?

When taking a boiler out of service, closing the vent is not a recommended action. Proper venting is crucial for safety and ensures that any residual gases or pressure within the system can safely escape. Ventilation allows for the free flow of air, which helps to prevent the risk of a pressure buildup that could lead to dangerous situations. Ensuring that the vent remains open is part of safe practice and compliance with regulations when decommissioning a boiler.

In contrast, securing the fire, draining the system, and shutting down the burners are important steps when taking a boiler out of service. Securing the fire means ensuring that the combustion process is halted, which is essential for safety and preventing any unintentional fires. Draining the system is necessary to remove water from the boiler to prevent freezing in colder conditions or to prepare for maintenance repairs. Shutting down the burners also eliminates fuel supply, ensuring that the system is completely off before any further procedure is taken. Each of these actions contributes to a systematic and safe approach to decommissioning a boiler.
