What should be checked before operating a boiler system?

Before operating a boiler system, it is essential to check both the water levels and the expansion tank levels. Proper water levels are critical for the safe and efficient operation of a boiler. If the water level is too low, it can lead to overheating and potentially catastrophic failure of the boiler due to lack of proper cooling. Additionally, checking the expansion tank levels ensures that there is enough space for water to expand as it heats up, which prevents pressure build-up that can cause system failure.

Regular monitoring of these levels helps maintain safe operating conditions and ensures the boiler functions correctly. It is not sufficient to rely solely on the manufacturer's manual or other specific factors like fuel levels or steam pressure, as these do not encompass the complete picture needed for safe operation. Ensuring that both the water levels and expansion tank levels are appropriate is a critical step in preventing accidents and ensuring the longevity of the boiler system.
