				circulation through an external heating system.
(10) "Hot water supply boiler" means a
				boiler, completely filled with water, intended for operation at pressures not

(11) "Inspector" means a
				state inspector or special boiler inspector.
(12) "Internal inspection" means as complete

(18) "Power boiler" means a boiler in which
				steam or other vapor is generated at a pressure of more than 15 psig.
(19) "Pressure vessel" means an unfired
				closed container in which pressure is obtained from an external source, the
				application of heat from an indirect source or from a direct source other than
				a boiler.
(20) "PSIG" means pounds

(24) "State boiler
				inspector" means a person employed by the department for the purpose of
				inspecting boilers.
(25) "State
				special boiler" means a boiler that is not a standard boiler, which must be
				granted a special operating certificate by the department prior to being
				operated.
(26) "Steam heating
				boiler" means a steam or vapor boiler operated at pressures not exceeding 15
				psig.
(27) "Temporary boiler" means
				a boiler, such as a portable rental boiler, which is intended to be utilized at
				a temporary location and such usage permits it to be readily moved from one
				location to another.
(28) "Traction
