(p) "Hot water supply boiler" means a boiler furnishing hot water to be used externally to the system at pressures not exceeding one hundred sixty psig and/or temperatures not exceeding 250 degrees F; however, it shall not include any units when none of the following limitations is exceeded:

(1) Heat input of 200,000 BTU per hour

(2) Water temperature of 210 degrees F

(3) Nominal water containing capacity of 120 gallons.

Electrically heated vessels may be constructed to either Section I, IV or VIII of the A.S.M.E. Code.

(q) "Hot water heater" means a closed vessel in which water is heated by the combustion of fuels, electricity, or any other source and withdrawn for external use to the system at pressures not exceeding 160 psig (1100 Kpa gage) and shall include the apparatus by which heat is generated and all controls and devices necessary to prevent water temperatures from exceeding 210 degrees F. (99 degrees C.).

(r) "Inspector" means any deputy inspector or any special inspector.

(s) "Internal inspection" means an inspection made when a boiler is shut down and handholes or manholes are opened for inspection of the interior.

(t) "Locomotive boiler" means a boiler mounted on a self-propelled track locomotive and used to furnish motivating power for traveling on rails. It does not include locomotive cranes, tractors or other self-propelled apparatus.

(u) "Low pressure heating boiler" means a boiler operated at pressures not exceeding fifteen psig steam or at water pressures not exceeding one hundred sixty psig and temperatures not exceeding 250 degrees F.

(v) "Major repair" means a repair upon which the strength of a boiler would depend.

(w) "Miniature boiler" means any boiler which does not exceed any of the following limits: sixteen inches inside diameter of shell; five cubic feet gross volume exclusive of casing and insulation, twenty square feet of water heating surface, one hundred psig allowable working pressure.

(x) "National Board" means the National Board of Boiler and Pressure Vessel Inspectors whose headquarters is 1055 Crupper Avenue, Columbus, Ohio 43229.

(y) "New boiler installations" means and includes all boilers constructed, installed, placed in operation or "contracted for" on or after January 1, 1986.

(z) "Nonstandard boiler" means a boiler that does not bear the state stamp, the A.S.M.E. stamp, the National Board stamp, or the stamp of any state or political subdivision which has adopted a standard of construction equivalent to that prescribed by these regulations.

(aa) "Owner or user" means any person, firm or corporation owning or operating any boiler within this state.

(bb) "Portable boiler" means a boiler, the construction and usage of which is obviously portable.

(cc) "Power boiler" means a closed vessel in which steam or other vapor (to be used externally to itself) is generated at a pressure of more than fifteen psig by the direct application of heat.

(dd) "Psig" means pounds per square inch gage.

(ee) "Reinstalled boiler" means a boiler removed from its original setting or location and re-erected at the same location or erected at a new location without change of ownership.

(ff) "Second-hand boiler" means a boiler of which both the location and ownership have been changed after primary use.

(gg) "Special inspector" means an inspector holding a Connecticut commission, and who is regularly employed by an insurance company authorized to insure against loss from explosion of boilers in this state.

(hh) "Standard boiler" means a boiler which bears the State of Connecticut, the A.S.M.E. stamp or the stamp of another state political subdivision which has adopted a standard of construction equivalent to that required by these regulations.

(kk) "Repair-Pressure Relief Valve" means the replacement, remachining, or cleaning of any critical part, lapping of seat, and disk or any other operation which may affect the flow passage, capacity function, or pressure retaining ability of the valve. Disassembly, reassembly and/or adjustments which affect the pressure relief valve function are also considered a repair.

(ll) "Safety Valve" means a pressure relief valve actuated by inlet static pressure and characterized by rapid opening or pop action.

(mm) "Safety Relief Valve" means a pressure relief valve characterized by rapid opening or pop action, or by opening in proportion to the increase in pressure over opening pressure, depending on application.

(nn) "Relief Valve" means a pressure relief valve actuated by inlet static pressure having a gradual lift generally proportional to the increase in pressure over opening pressure. It may be provided with an enclosed spring housing suitable for closed discharge system application and is primarily used for liquid service.
