This Section covers general descriptions, terminology and operation guidelines applicable to steel and cast iron boilers limited to the operating ranges of Section IV Heating Boilers. It includes guidelines for associated controls and automatic fuel burning equipment. Illustrations show typical examples of available equipment. Also included is a glossary of terms commonly associated with boilers, controls, and fuel burning equipment. Careful application of this Section will help users to comply with applicable regulations within their jurisdictions, while achieving the operational, cost and safety benefits to be gained from the many industry best-practices detailed within these volumes. All changes to this 2013 Edition are incorporated into the appropriate page and each affected area is identified with a designator. Each Section includes a Summary of Changes that lists the material affected by the change, plus the nature of the change. There will no longer be Addenda service for this 2013 Edition or for future Editions. Intended for manufacturers, users, constructors, designers and others concerned with the design, fabrication, assembly, erection, examination, inspection and testing of pressure vessels, plus all potential governing entities.
