      (1)   Any dense smoke, noxious fumes, gas and soot, or cinders, in unreasonable quantities, or any use of an external solid fuel-fired heating device to burn solid fuels other than those solid fuels for which the external solid fuel-fired heating device was designed, is declared a public nuisance.
      (2)   No person may install, use, or operate an external solid fuel fired heating device on a lot less than four acres in size.
      (3)   All stacks or chimneys must be so constructed to withstand high winds or other related elements and in accordance to the specifications of the manufacturer of the external solid fuel-fired heating device. The stack height shall be a minimum of 25 feet above ground level, but shall also extend at least as high as the height of the roofs of residents within 500 feet. All stacks or chimneys must be of masonry or insulated metal with a minimum six-inch flue.
      (4)   All external solid fuel-fired heating devices must be setback a minimum of 50 feet from all property lines.
      (5)   All external solid fuel-fired heating devices must be setback a minimum of ten feet from any principal or accessory structure.
   (C)   Fuels.
      (1)   Only fuels designed for burning in an external solid fuel-fired heating device may be burned. No garbage may be burned in an external solid fuel-fired heating device.
