Current through Vol. 24-12, July 15, 2024
Rule 603. All utility hookups to a home shall be in
					 compliance with the following minimum standards:
(a) Water: Each home shall be connected to
				  the service outlet by semirigid tubing, such as copper tubing or approved
				  plastic piping. The minimum size of the threaded inlet connection shall be 3/4
				  of an inch An easily accessible, hand-manipulated shutoff valve shall be
				  installed on the water supply inlet to the home. A water supply protection
				  device, such as a heat tape, which is approved to be sold or for use in this
				  state by the state construction code commission and which is designed for use
				  with homes, shall be installed at the time the home is installed on a home site
				  to prevent service lines, valves, and riser pipes from freezing. The water
				  service riser shall be insulated and covered to prevent the loss of heat. If an
				  extension cord is used, it shall be listed by underwriters laboratories or by a
				  similar organization and shall be approved for exterior use. The protection
				  device shall be installed in compliance with the manufacturer's specifications
				  as approved by the state construction code commission.
It is the responsibility of the resident to provide
					 protection for the water line from 1 inch beyond the underside of the home to
					 30 inches below the surface of the ground within the water crock or to the
					 bottom of the crock, whichever is less.
(b) Home fuel supply systems shall be in
				  compliance with all of the following provisions:
(i) Furnaces, hot water heaters, appliances,
				  or any item of equipment that uses gas shall be fully compatible with the type
				  of gas used. All fuel-burning appliances, except ranges, ovens, illuminating
				  appliances, clothes dryers, solid fuel-burning fireplaces, and solid
				  fuel-burning fireplace stoves, shall be installed to provide for the complete
				  separation of the combustion system from the interior atmosphere of the home.
				  Combustion air inlets and flue gas outlets shall be listed or certified as
				  components of the appliance. The required separation may be obtained by
				  installing direct vent system (sealed combustion system) appliances or by
				  installing appliances within enclosures so as to separate the appliance
				  combustion system and venting system from the interior atmosphere of the home
				  and ensuring that there is no door, removable access panel, or other opening
				  into the enclosure from the inside of the home and that any opening for ducts,
				  piping, wiring, or similar items is sealed. This paragraph applies to the
				  installation of the systems specified in this paragraph in new and pre-owned
				  homes.
(ii) An easily accessible,
				  approved, hand-manipulated shutoff valve controlling the flow of gas to the
				  entire gas piping system shall be installed as close as possible to the service
				  meter or supply connection of the liquefied petroleum gas container. Approved
				  piping that has a 1/2-inch or more inside diameter shall be used for any gas
				  line. After the home is connected to the service meter or supply connection,
				  the piping system shall be tested to not less than 10 inches nor more than 14
				  inches of water column (1/2 psi). An appliance connection shall be tested for
				  leakage with soapy water or bubble solution.
(iii) A fuel supply system other than gas
				  shall be in compliance with state codes.
(iv) Fuel supply meters, regulators, shutoff
				  valves, and pedestals shall not be located under a home or within a skirted
				  area.
(v) Natural gas, liquefied
				  petroleum gas (LPG), and fuel oil piping that connects the home to the service
				  pedestal or tank shall be installed underground if the distance between the
				  pedestal or tank and the home is more than 2 feet.
