Current through all regulations passed and filed through July 1, 2024
As used in Chapters 4101:4-1 to 4101:4-10 of the Administrative

(A) "Alteration" means any
			 change in the item described on the original manufacturer's data report which
			 affects the pressure containing capability of the boiler or pressure vessel.
			 Non physical changes such as an increase in the maximum allowable working
			 pressure (internal or external) or design temperature of a boiler or pressure
			 vessel 
								are considered alterations. A reduction in
			 minimum temperature such that additional mechanical tests are required
			 
								is also
			  considered an alteration.
(B) "ASME" means the "American Society of
			 Mechanical Engineers". Referenced standards, codes, and related technical
			 information developed by this organization can be purchased by logging on to

or by calling
			 1-800-the-asme.
(C) "Authorized
			 Inspection Agency" means an entity, accepted by the "National Board," that
			 provides third party inspection services in which boilers and pressure vessels
			 are inspected during construction, repairs, and alterations to verify their
			 conformity with the code of construction adopted by the board of building

			 conservation of energy, and operation of boilers and for the construction and
			 repair of pressure vessels.
(F)
			 "Boiler" means a closed vessel in which water is heated, steam is generated,
			 steam is superheated, or any combination thereof, under pressure or vacuum for
			 use externally to itself by the direct application of heat from the combustion
			 of fuels, or from electricity or nuclear energy. The term boiler
			 includes fired units for heating or vaporizing liquids
			 other than water where these units are separate from processing systems and are
			 complete within themselves.
(G)
			 "Boiler, high pressure, high temperature water" means a water heating boiler
			 operating at pressures exceeding one hundred sixty psig or temperatures
			 exceeding two hundred fifty degrees Fahrenheit.
(H) "Boiler, low pressure" means a steam
			 boiler operating at pressures not exceeding fifteen psig, or a hot water
			 heating boiler operating at pressures not exceeding one hundred sixty psig or
			 temperatures not exceeding two hundred fifty degrees Fahrenheit.
(I) "Boiler, portable" means a boiler which
			 is primarily intended for temporary use and the construction and usage of which
			 is obviously portable.
(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.
