A.Â
Installation and maintenance. Chimneys, flues, gas vents
and their supports shall be installed and maintained so as to be structurally
safe, durable, smoketight, noncombustible and capable of withstanding the
action of flue gases without softening, cracking, corroding or spalling. Chimneys,
flues and gas vents shall be installed and maintained so that, under conditions
of use, the temperature of any combustible material adjacent thereto, insulated
therefrom or in contact therewith does not exceed a safe temperature.
B.Â
Conveyance of products of combustion. Such facilities
shall effectively convey the products of combustion to the outer air.
C.Â
Masonry chimney foundations. Masonry chimneys, except
approved prefabricated chimneys, shall have noncombustible foundations.
D.Â
Flue linings. Flue linings shall be capable of withstanding
the action of flue gas without softening, cracking, corroding or spalling
at the temperature to which they will be subjected.
E.Â
Openings for connections. Openings for smoke pipes or
gas vent connections shall be provided with means for easy connection without
restriction of flue.
F.Â
Limitation on connections. No flue shall have smoke pipe
or gas vent connections in more than one (1) story of the building.
A chimney or flue connected to an incinerator and a chimney or flue
which may emit sparks shall be provided with a spark arrester of noncombustible
construction. Spark arresters shall have sufficient total clear area to permit
unrestricted passage of flue gases. Openings in spark arresters shall be of
such size as to prevent passage of embers and to minimize clogging by soot.
