      3.   HVAC Equipment: Equipment located in attics shall be within the thermal envelope of the building.
   (C)   Electrical Wiring Requirements:
      1.   Commercial Buildings: All electrical wiring in new buildings which classify as commercial or building of public assembly in commercial, general commercial or central business districts according to the official zoning map shall be required to be in metal raceways, or other UL approved raceways.
      2.   Public Assembly Areas: All electrical wiring in places of public assembly, including, but not limited to, schools, churches, fraternal orders, hospitals, rest homes, sanatoriums, exhibition or entertainment buildings, whether publicly or privately owned or operated, shall be in metal raceways, or other UL approved raceways.
      3.   Exception To The Foregoing Provisions: Conductor operating at thirty (30) volts or less may be installed by any method.
      4.   Electrical Wiring In Metal Raceways In Residential Buildings:

   (D)   Liquefied Petroleum Gas (LPG) System Requirements: These requirements shall apply to all new liquefied petroleum gas (LPG) installations, including residential and commercial systems, and to existing installations when LPG service is reconnected after service is interrupted. LPG providers shall install systems following NFPA 54 & 58, including:
      1.   Two-stage regulator systems, or twin packing regulators underneath the tank lid, shall be installed on all LPG installations, with twin packing preferred.
      2.   The first stage regulator shall be installed under the hinged gauge cover supplied with the tank. The atmospheric pressure aperture of the regulator shall point downward. The first stage regulator shall be plumbed to the riser of the yard piping with a flexible riser to allow flexibility should tank shifting occur. The riser from the yard piping shall be located not more than twelve (12) inches from the walls of the tank.

The penetrating building nipple shall be schedule 80. The outside hookup to the nipple shall also be schedule 80. This riser shall be a flexible riser pipe and shall be securely supported/braced to the wall approximately ten (10) inches below the regulator to prevent bending of the pipe by lateral snow/ice loads.
      4.   A protective cover, approved by the gas supplier and the fire district, shall be installed over all second stage regulators/or meters and riser piping, and securely supported to the ground or diagonally to the building wall.

Such stake shall be of sufficient height to be visible through anticipated maximum snow depth at the respective location. Installation and maintenance of the snow stake is the responsibility of the LPG user.
      7.   Propane appliances shall not be permitted in any new installation in an attic or crawl space, effective May 1, 2020. Installation in an attic or crawl space will be allowed if combustible gas detection is built into a system that shuts down the supply of propane in the event of a leak.
      8.   A combustible gas detector shall be installed in the lowest livable level of any building with an LPG appliance at the time of installation. Maintenance of the combustible gas detector shall be the responsibility of the LPG user.

      10.   The propane company, after installation of a propane system, shall submit an LPG permit application to the appropriate fire district. The permit application shall include an LPG system plot plan. The LPG plot plan shall include, but not be limited to, the tank location, tank capacity in U.S. gallons, route of yard piping, location of the riser pipe at the building, property boundaries, an outline of all existing/proposed building on the lot and a depiction of the ridgeline of any building to be supplied with LPG. If service is interrupted and a new tank is being set, the LPG system plot plan shall be submitted to the local fire district, along with an LPG permit application.
