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.

(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.
