(1) The steam in the boiler is either generated or superheated, or both, under pressure or vacuum for use external to itself.
(2) The source of heat for the boiler is, in part or in whole, from a process other than the boiler itself.

The written report, completed by a general or special inspector, when filed in the office of the superintendent, shall be the basis on which a certificate of operation may be granted or denied. The certificate of inspection would then be replaced with a certificate of operation, if granted.
