				  and repair of all piping, fixtures and appliances related to water supply,
				  including pressure vessels and tanks (excluding municipal or related water
				  supply systems); venting and sanitary drainage systems for all fluid,
				  semifluid, and organic wastes; septic tanks and leaching lines; roof leaders;
				  lawn sprinkler systems; water conditioning equipment; piping and equipment for
				  swimming pools.
Also included are piping, fixtures, appliances, and pressure
				  vessels for manufactured and natural gases, compressed air and vacuum systems,
				  petroleum, fuel oil, nonpotable liquids, hot water heating and hot water supply
				  systems operating at pressures not exceeding 30 PSIG or temperatures not
				  exceeding 220° F; steam heating and steam supply systems not exceeding 15
				  PSIG operating pressure; gas or oil fired space heaters and furnaces excluding
				  duct work. Piping for water cooling systems, excluding the refrigerant piping
				  and equipment. Testing and balancing of hydronics systems.
Sewer, gas, water lines, and connections from structure to
				  the nearest point of public supply or disposal may cross public or private
				  easements or be installed within private easements. Pipe installed across
				  public property may not be increased in size or make any other connection
				  between the point of exit from private property to point of connection at
				  public supply or disposal. These lines shall not be installed parallel to main
				  lines in public easements or right-of-ways.
C-78 SOLAR PLUMBING LIQUID SYSTEMS ONLY
This classification allows the licensee to install, alter,
				  and repair solar water heating systems operating at temperatures not exceeding
				  220° F, including thermosyphon, direct (open loop), and indirect (closed
				  loop), but excludes air as a transfer medium.
Includes installation of collectors, storage and expansion
				  tanks, heat exchangers, piping valves, pumps, sensors and low voltage controls
				  which connect to existing plumbing and electrical stubouts at the water tank
				  location.
Installation of solar water heating systems for swimming
				  pools which tie into and operate from the conventional pool systems, but
				  excludes all non-solar plumbing, electrical and mechanical systems and
				  components.
Installation of backup and auxiliary heating systems only
				  when such systems are included in the original contract and when such systems
				  are an integral part of the solar collector or storage equipment.
C-79 AIR CONDITIONING AND REFRIGERATION, INCLUDING
				  SOLAR
This classification allows the licensee to install, alter,
				  and repair refrigeration and evaporative cooling systems, including
				  solar.
This classification also allows for installation alteration,
				  and repair of heating systems of "wet", "dry" or radiant type. "Wet" systems
				  include steam, or hot water boilers and coils, or baseboard convectors and are
				  limited to 30 PSIG operating pressure of 220° F for hot water and 15 PSIG
				  operating pressure for steam. Dry systems include gas fired furnaces and space
				  heaters.
This classification also allows for installation alteration,
				  and repair of ventilation systems.
Installation of these systems include duct work, air
				  filtering devices, water treatment devices, pneumatic or electrical controls,
				  and control piping. Thermal and acoustical insulation, vibration isolation
				  materials and devices, liquid fuel piping and tanks, and water and gas piping
				  from service connection to equipment it serves. Testing and balancing of
				  refrigerant, cooling and heating circuits, and air handling systems.
If necessary, a new circuit may be added to the existing
				  service panel or sub-panel. Excluded is the installation of a new service panel
				  or sub-panel.
