used solely for agricultural purposes.
        (7) Steam boilers of a miniature model locomotive,
    
boat, tractor, or stationary engine constructed and maintained as a hobby and not for commercial use, that have an inside diameter not exceeding 12 inches and a grate area not exceeding 1 1/2 square feet, provided they are constantly attended while in operation and are equipped with a water level indicator, pressure gauge, and a safety valve of adequate capacity.
        (8) Pressure vessels regulated and inspected under
    
the Illinois Fertilizer Act of 1961.
        (9) Pressure vessels containing liquefied petroleum

    (b) The following boilers and pressure vessels shall be exempt from the requirements of Sections 10, 11, 12, and 13 of this Act:
        (1) Steam boilers used for heating purposes and
    
operated at a pressure not in excess of 15 pounds per square inch gauge (psig) and having a rating not in excess of 200,000 B.T.U. per hour input.
        (2) Hot water heating boilers operated at a pressure
    
not in excess of 30 psig and having a rating not in excess of 200,000 B.T.U. per hour.
        (3) Boilers and pressure vessels, located in private
    
residences or in multi-family buildings having fewer than 6 dwelling units.
        (4) Hot water supply boilers that are directly fired
    
with oil, gas, or electricity when none of the following limitations are exceeded:
            (A) Heat input of 200,000 BTU per hour.
            (B) Water temperature of 200 degrees Fahrenheit.
            (C) Nominal water containing capacity of 120 U.S.
        
gallons.
        (5) Coil type hot water boilers where the water can
    
flash into steam when released directly to the atmosphere through a manually operated nozzle provided the following conditions are met:
            (A) There is no drum, headers, or other steam
        
space.
            (B) No steam is generated within the coil.
            (C) Outside diameter of tubing does not exceed 1
        
inch.
            (D) Pipe size does not exceed 3/4 inch NPS.
            (E) Water capacity of unit does not exceed 6 U.S.
        
gallons.
            (F) Water temperature does not exceed 350 degrees
        
Fahrenheit.
        (6) Pressure vessels containing only water under
    
pressure for domestic supply purposes, including those containing air, the compression of which serves only a cushion or airlift pumping function.
        (7) Pressure vessels operated at a pressure not
    
exceeding 15 psig with no limitation on size.
        (8) Pressure vessels that do not exceed:
            (A) Both a volume of 15 cubic feet and 250 psig
        
when not located in a place of public assembly.
            (B) Both a volume of 5 cubic and 250 psig when
        
located in a place of public assembly.
            (C) A volume of 1 1/2 cubic feet or an inside
        
diameter of 6 inches with no limitation on pressure.
        (9) Water conditioning equipment used for the removal
    
of minerals, chemicals, or organic or inorganic particles from water by means other than application of heat including, without limitation, water softeners, water filters, dealkalizers, and demineralizers.
        (10) Steam boilers of railroad locomotives and
    
traction engines built prior to 1955 that were constructed or operated in compliance with the Federal Locomotive Inspection Law and are in the permanent collection of a museum or historical association are exempt from the requirements of subsection (c) of Section 10 upon proof of such construction or inspection being furnished to the Board.
