What action must be taken when a boiler is put into service?

When a boiler is put into service, ensuring that the water supply is adequate is a crucial first step. An adequate water supply is essential for various reasons, including maintaining the proper water level in the boiler, which is necessary for safe and efficient operation. If the water level is too low, it can lead to overheating and potentially cause serious damage or even catastrophic failure. Additionally, having a sufficient supply of water allows for effective heat exchange, maintaining proper temperature and pressure within the boiler system.

Other considerations, such as checking air quality or performing a boiler blowdown, may also be important in the overall maintenance and operation of a boiler, but they do not replace the crucial action of ensuring that there is an adequate and safe water supply available for the boiler. Sealing all openings may be a part of routine maintenance or service checks, but it is not the immediate action required when putting a boiler into operation.
