§40-33 Number and Capacity of Gas-Fueled Heaters

   (a)   Where gas-fueled heaters are permitted to be installed in lieu of the required centrally supplied heat, each "living room," as such term is defined in subdivision 18 of § 4 of the Multiple Dwelling Law, shall be heated by a heater placed in such room or in an adjoining room which connects with it except that a room whose exterior walls are exposed only on a fully enclosed inner court may be heated by a heater located one room removed from such room. For this purpose, an inner court shall be considered fully enclosed even though some of the enclosure walls are located on an adjoining lot. The aggregate input capacity of the heater or heaters installed in any apartment shall not be less than the number of living room times ten thousand (10,000) British thermal units per hour.
