(7) pressure vessels having an inside diameter not exceeding six inches;

(8) every vessel that contains water under pressure, including those containing air
that serves only as a cushion, whose design pressure does not exceed 300 p.s.i.g. and
whose design temperature does not exceed 210 degrees Fahrenheit;

(9) boiler or pressure vessels located on farms used solely for agricultural or

750,000 BTU per hour;

(14) hot water supply boilers (water heaters) not exceeding a heat input of 500,000
BTU per hour, a water temperature of 210 degrees Fahrenheit, a nominal water capacity of
120 gallons, or a pressure of 160 p.s.i.g.;

(15) a laundry and dry cleaning press not exceeding five cubic feet of steam volume;

(16) pressure vessels operated full of water or other liquid not materially more
hazardous than water, if the vessel's contents' temperature does not exceed 140 degrees
Fahrenheit or a pressure of 200 p.s.i.g.;

(17) steam powered turbines at papermaking facilities which are powered by steam
generated by deleted text begin municipal deleted text end steam deleted text begin district deleted text end facilities at a remote location; and

(18) manually fired boilers for model locomotive, boat, tractor, stationary engine,
or antique motor vehicles constructed or maintained only as a hobby for exhibition,
educational or historical purposes and not for commercial use, if the boilers have an
inside diameter of 12 inches or less, or a grate area of two square feet or less, and are
equipped with an ASME stamped safety valve of adequate size, a water level indicator,
and a pressure gauge.

(b) An engineer's license is not required for hot water supply boilers.

(c) An engineer's license is not required for boilers, steam cookers, steam kettles,
steam sterilizers or other steam generators not exceeding 100,000 BTU per hour input, 25
kilowatt, 2-1/2 horsepower and a pressure of 15 p.s.i.g.

(d) Electric boilers not exceeding a maximum working pressure of 50 p.s.i.g.,
maximum of 30 kilowatt input or three horsepower rating shall be inspected as pressure
vessels and shall not require an engineer license to operate.
