(J) "Boiler, potable water heater" means a boiler used for supplying potable hot water for commercial purposes at pressures not exceeding one hundred sixty psig and temperatures not exceeding two hundred ten degrees Fahrenheit, except that water heaters are exempted when none of the following limitations are exceeded:

(1) Heat input of two hundred thousand Btu per hour;

(2) Water temperature of two hundred ten degrees Fahrenheit;

(3) Nominal water-containing capacity of one hundred twenty gallons.

(K) "Boiler, power" means a boiler in which steam or other vapor, to be used externally to itself, is generated at a pressure of more than fifteen psig.

(L) "Boiler, process" means a boiler to which all of the following apply:

(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.

(P) "Certificate of operation" means the certificate issued by the superintendent to the owner or user following the general or special inspector's inspection of a boiler in accordance with section 4104.12 of the Revised Code.

(Q) "Code stamp" means the permanent "ASME" identifying stamping applied to boilers and pressure vessels which indicates that the vessel has been constructed in accordance with the rules of the board and the applicable section of the "ASME Boiler and Pressure Vessel Code" and has been approved by an authorized inspector.
