Periodic testing of all boiler controls and safety devices is required to ensure they continue to
operate as designed. Precautions must be taken while tests are being performed to protect
against bodily injury and property damage. The owner or user of an automatic boiler system
should set up a formal system of periodic preventive maintenance and testing. Tests should
be conducted on a regular basis and the results recorded in a log-book.
