A.
Except as otherwise mandated by federal law or regulation,
residential buildings intended for occupancy between the 15th day
of September and the 15th day of June of the following year shall
be provided with heating equipment designed to maintain a temperature
of not less than 68º F. at a distance of three feet from exterior
walls and at a level of five feet above the floor, in habitable spaces,
kitchenettes, bathrooms and toilet rooms. The capability of the heating
equipment to maintain such indoor temperatures shall be based on an
outside temperature of -10º F.
B.
Except as otherwise mandated by federal law or regulation,
in multiple dwellings, adequate heat shall be provided to maintain
the indoor temperature in habitable spaces, kitchenettes, bathrooms
and toilet rooms at 68º F. from September 1 to June 30 of the
following year when the outside temperature falls below 55º F.
Fuel-burning heat-producing equipment shall
be installed and maintained so as not to violate the Fire Prevention
Code in force in the City.
Ducts and other air-handling equipment used
for heating shall conform to the requirements of such equipment used
for ventilating purposes.
Fuel-burning water heaters shall not be located
in sleeping rooms, bathrooms or toilet rooms.
Fuel-burning equipment shall be permanently
fastened and connected in place. Fuel supply connections to such equipment
shall be made with approved pipe or with an approved flexible tubing
connector and be protected against mechanical injury and corrosion.
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-fired heat producing equipment and the enclosure
in which it is located shall be provided with a supply of air adequate
to replenish that consumed by complete combustion at the rated gross
output of the equipment and for the ventilation of the enclosure to
prevent the accumulation of heat.
B.
Such air shall be supplied by means of one or more
openings to the exterior or by means of fixed openings to interior
spaces which open to the exterior.
A.
Equipment for burning solids 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.
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 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.
Equipment capable of developing hazardous pressures
or temperatures shall be provided with means to relieve safely such
pressures and temperatures.
B.
Controls for the safe operation of automatically operated
heat-producing equipment shall be provided to function as follows:
(1)
When failure or interruption of flame or ignition
occurs, the fuel supply shall be cut off.
(2)
When a predetermined temperature or pressure is exceeded,
the input of additional heat shall be prevented or reduced to a safe
rate.
(3)
When the water level in a steam boiler boils below
a predetermined level, the fuel supply shall be cut off.
(4)
When failure or interruption of pilot light or main
burner in gas equipment occurs, the fuel supply to each pilot light
and main burner shall be cut off.
Fuel-burning equipment for garages serving multiple
dwellings shall be located in heater rooms, except that equipment
burning gas or liquid fuel located in the vehicle garage space shall
be permitted in stories at or above grade where the equipment is elevated
so as not to be exposed to possible accumulation of flammable gases.
