8.1.1 — Periodic Inspection
Insurance regulations and local laws require periodic inspection of the pressure vessel by an authorized inspec-
tor. Inspections are usually, though not necessarily, scheduled for periods of normal boiler down time, such as an
off season. This major inspection can often be used to accomplish maintenance, replacement or repairs that can-
not easily be done at other times. Inspection also serves as a good basis for establishing a schedule for annual,
monthly, or other periodic maintenance programs.
While the inspection pertains primarily to the waterside and fireside surfaces of the pressure vessel, it provides
the operator an excellent opportunity for detailed inspection and check of all components of the boiler including
piping, valves, pumps, gaskets, refractory, etc. Comprehensive cleaning, spot painting or repainting, and the
replacement of expendable items should be planned for and taken care of during this time. Any major repairs or
replacements that may be required should also, if possible, be coordinated with the period of boiler shutdown.
Cleaver-Brooks boilers are designed, engineered, and built to provide long life and excellent service. Good oper-
ating practices and conscientious maintenance and care will assure efficiency and economy from their operation,
and will contribute to many years of performance.
