Rye, N.Y., Code of Ordinances ch. 108 § 108-27

A. General requirements. (1) Residential occupancies. Dwellings shall be provided with heating facilities capable of maintaining a room temperature of 68° F. (20° C.) in all habitable rooms, bathrooms and toilet rooms based on the winter design dry-bulb temperature for the locality indicated in the Energy Conservation Construction Code of New York State. Cooking appliances shall not be used to provide space heating to meet the requirements of this section. Exception: owner-occupied, one-family dwellings. (2) Heat supply. Every owner and operator of any building who rents, leases or lets one or more dwelling units, rooming units, dormitories or guest rooms on terms, either expressed or implied, to furnish heat to the occupants thereof shall supply heat during the period from September 15 to May 31 to maintain a temperature of not less than 68° F. (20° C.) in all habitable rooms, bathrooms and toilet rooms. Exception: When the outdoor temperature is below the winter outdoor design temperature for the locality, maintenance of the minimum room temperature shall not be required, provided that the heating system is operating at its full design capacity. The winter design dry-bulb temperature for the locality shall be as indicated in the Energy Conservation Construction Code of New York State. (3) Occupiable work spaces. (a) Indoor occupiable work spaces shall be supplied with heat during the period from September 15 to May 31 to maintain a temperature of not less than 65° F. (18° C.) during the period the spaces are occupied. (b) Exceptions: [1] Processing, storage and operation areas that require cooling or special temperature conditions. [2] Areas in which persons are primarily engaged in vigorous physical activities. (4) Occupiable public spaces. Indoor public spaces shall be supplied with heat during the period from September 15 to May 31 to maintain a temperature of not less than 68° F. (20° C.) in accordance with the Building Code of New York State during the period the spaces are occupied. (5) Room temperature measurement. The required room temperatures shall be measured three feet (914 mm) above the floor near the center of the room and two feet (610 mm) inward from the center of each exterior wall. B. Smoke control. Fuel-burning heat-producing equipment shall be installed and maintained so that the emission or discharge into the atmosphere of smoke, dust, particles, odors or other products of combustion will not create a nuisance or be detrimental to the health, comfort, safety or property of any person. C. Warm-air heating. Ducts and other air-handling equipment used for heating shall conform to the requirements of such equipment used for ventilating purposes. D. Prohibited locations for heat-producing equipment. Fuel-burning water heaters shall not be located in sleeping rooms, bathrooms or toilet rooms. E. Fuel supply connection. Fuel-burning equipment shall be permanently fastened and connected in place. Fuel supply connection to such equipment shall be made with pipe or tubing of solid metal. F. Installation and clearance. Where heat-producing equipment is installed on or adjacent to combustible materials, the location, insulation, clearance and the control of the equipment shall be such that the temperature on the surface of the combustible materials will not exceed a safe temperature. G. Air supply. (1) Direct-fired heat-producing equipment and the enclosure in which it is located shall be provided with a supply of air adequate both for complete combustion at the rated gross output of the equipment and for the ventilation of the enclosure to prevent the accumulation of heat. (2) Rooms containing fuel-burning equipment shall have such air supply provided by means of one or more openings to the exterior or by means of fixed openings to interior spaces which open to the exterior. H. Removal of products of combustion. (1) Equipment for burning solid or liquid fuel shall be connected to suitable chimneys or flues and shall not be connected to gas vents. Unvented heaters burning liquid fuel shall be prohibited. (2) Fuel-burning space heaters located in sleeping rooms or rooms normally kept closed shall be connected to a suitable chimney, flue or gas vent. (3) Gas-fired equipment shall be connected to a suitable chimney, flue or gas vent when the discharge of products of combustion into the space where the equipment is installed would be a hazard. I. Safety devices. (1) Equipment capable of developing hazardous pressures or temperatures shall be provided with means to relieve safely such pressures and temperatures. (2) Controls for the safe operation of automatically operated heat-producing equipment shall be provided to function as follows: When failure or interruption of flame or ignition occurs, the fuel supply shall be cut off. When a predetermined temperature or pressure is exceeded, the input of additional heat shall be prevented or reduced to a safe rate. When the water level in a steam boiler drops below a predetermined level, the fuel supply shall be cut off. When failure or interruption of pilot light or main burner of liquefied petroleum gas equipment occurs, the fuel supply to each pilot light and main burner shall be cut off. J. Heating of garages. Fuel-burning equipment for garages servicing multiple dwellings shall be located in heater rooms, except that equipment burning gas or liquid fuel, located in the vehicle storage space, shall be permitted in stories at or above grade where elevated so as not to be exposed to possible accumulation of flammable gases.
