A.
Residential buildings. Residential buildings intended
for occupancy between the first day of November and the first day of May of
the following year shall be provided with heating equipment designed to maintain
a temperature of not less than seventy degrees Fahrenheit (70º F.) at
a distance of three (3) feet and more from exterior walls and at a level of
five (5) feet above the floor in habitable spaces, kitchenettes, bathrooms
and toilet rooms. The capability of the heating equipment to maintain such
indoor temperature shall be based on the average of the recorded annual minimum
outside temperatures for the locality.
B.
Multifamily dwellings. In multifamily dwellings, adequate
heat shall be provided to maintain the indoor temperature in habitable spaces,
kitchenettes, bathrooms and toilet rooms at not less than sixty-eight degrees
Fahrenheit (68º F.) at a distance of eighteen (18) inches above floor
level and three (3) feet from an outside wall.
[Amended 12-2-1980 by L.L.
No. 11-1980]
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.
Ducts and other air-handling equipment used for heating shall conform
to the requirements of such equipment used for ventilating purposes.
Fuel-burning equipment shall not be located in sleeping rooms, bathrooms
or toilet rooms, nor in or under stairways or other required exits.
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.
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.
A.
Direct fire heat-producing equipment; enclosures. Direct
fire 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.
B.
Rooms containing fuel-burning equipment. Rooms containing
fuel-burning equipment shall have such air supply provided by means of one
(1) or more openings to the exterior or by means of fixed openings to interior
spaces which open to the exterior.
A.
Equipment burning solid, liquid fuel. 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.
B.
Space heaters. Fuel-burning space heaters located in
sleeping rooms or rooms normally kept closed shall be connected to a suitable
chimney, flue or gas vent.
C.
Gas-fired equipment. 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.
A.
Pressure, temperature relievers. Equipment capable of
developing hazardous pressures or temperatures shall be provided with means
to relieve safely such pressures and temperatures.
B.
Controls for automatically operated equipment. Controls
for the safe operation of automatically operated heat-producing equipment
shall be provided to function as follows:
(1)
When failure or interruption of flames 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.
(2)
Hot water and steam boilers (natural gas, oil or LP, regardless
of BTU input or output) shall be provided with a low water cutoff and manual
reset hi limit temperature control.
[Added 4-12-2005 by L.L. No. 5-2005]
Fuel-burning equipment for garages servicing multifamily 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.
