[Ord. No. 250 Art. III §1, 12-3-1951]
All chimneys, flues or fireplaces hereafter built or rebuilt
in any building, within the Corporate limits, regardless of the type
of fuel used, shall conform to the provisions of this Chapter.
[Ord. No. 250 Art. III §2, 12-3-1951]
A. Chimneys
shall be built of brick, of solid masonry or of reinforced concrete,
not less than three and three-quarters (3¾) inches thick. Chimneys
shall be lined throughout the fire clay flue lining or with fire brick,
provided that chimneys for gas appliances only may be lined with any
approved corrosion resistant lining. Chimneys shall be built on concrete
or masonry foundations. Chimneys shall not rest upon or be carried
by wooden floors, beams or brackets, nor be hung from wooden rafters.
Iron brackets or stirrups attached to wooden construction shall not
be used to support chimneys. Footings for exterior chimneys shall
start below the frost line.
B. All
chimneys shall be built as nearly vertical as possible and shall extend
at least three (3) feet above the highest point at which they come
in contact with the roof of the building and at least two (2) feet
higher than any ridge within ten (10) feet of such chimney or flue.
[Ord. No. 250 Art. III §3, 12-3-1951]
Gas consuming devices which produce flue gas temperature not
in excess of fifty-five degrees Fahrenheit (55° F) at the outlet
of the draft hood may be vented to special flues in lieu of the above
when such special flues are of a type listed and approved by the Underwriter's
Laboratories, Inc., or a similarly recognized testing laboratory and
satisfactory to the Committee on Buildings and Grounds; provided however,
that such special vents shall not be permitted for incinerators, for
devices or appliances which may be readily converted to the use of
solid or liquid fuel, nor on boilers or furnaces except with specific
approval of said Committee.
[Ord. No. 250 Art. III §4, 12-3-1951]
A. The
back and sides of fireplaces shall be of solid masonry or reinforced
concrete, not less than eight (8) inches in thickness. A lining of
fire brick at least two (2) inches thick or other approved material
shall be used unless the overall thickness is twelve (12) inches.
B. Fireplaces
shall have hearths of brick, stone or other approved incombustible
material supported on a fireproof slab or brick trimmer arches. Such
hearths shall extend at least twenty (20) inches outside of the chimney
breast and not less than twelve (12) inches beyond each side of the
fireplace opening along the chimney breast. The combined thickness
of hearth and supporting arch shall be not less than six (6) inches
at any point.
C. Wooden
forms or centers used in the construction of that part of the supporting
construction which is below the hearth of the fireplace shall be removed
when the supporting construction of the hearth is completed and before
plastering on the underside.
[Ord. No. 250 Art. III §5, 12-3-1951]
All wooden and other combustible construction shall be kept
at least two (2) inches from chimneys and flues and shall be kept
at least four (4) inches from the back of a fireplace. Such spaces
shall be firestopped with non-combustible material.
[Ord. No. 250 Art. III §6, 12-3-1951]
A. Heating
appliances shall not be mounted on floors of combustible construction
unless they are either approved by the Committee on Building and Grounds
as suitably designed for such mounting or are set on approved bases
of insulating value sufficient to prevent overheating of the combustible
construction.
B. Ranges,
stoves, heating furnaces and similar heating appliances without legs
or with legs less than four (4) inches high, if on floors of combustible
construction, shall have such floors protected by masonry at least
eight (8) inches in thickness, topped with boiler iron and arranged
in a manner that will provide air circulation throughout the masonry.
C. Similar
heating appliances with legs which provide not less than four (4)
inches open space under the base of the appliance, if on floors of
combustible construction, shall have such floors protected with incombustible
material.
D. Protection
shall be provided for at least that portion of the combustible floor
which is under the heating appliances, and if the appliance uses solid
fuel, suitable protection shall also be provided for a distance of
not less than eighteen (18) inches at the front or side where ashes
are removed.
[Ord. No. 250 Art. III §7, 12-3-1951]
A. Ranges,
stoves, heating furnaces and all other heating appliances shall be
installed to provide safe clearances to woodwork or other combustible
material, whether plastered or not.
B. Ranges,
stoves, heating furnaces, and similar heating appliances and smokepipes
from such devices shall have a clearance of at least eighteen (18)
inches to walls, ceilings or partitions of combustible construction
or to any other combustible material. Appliances of special types
which have been tested and found safe for installation with lesser
clearances may be installed with such clearances as the said Committee
shall approve. Where a durable form of non-combustible heat insulating
protection is applied to the appliance or to the combustible material,
installation may be made with lesser clearance as the Committee on
Buildings and Grounds may approve.
[Ord. No. 250 Art. III §8, 12-3-1951]
A. Every
smokepipe shall connect with a chimney or other approved flue. No
smokepipe shall pass through any floor, ceiling, roof or wall of combustible
construction except that metal smokestacks from industrial heating
or process devices may be extended through roofs when metal ventilated
jackets or collars conforming to recognized good practices and acceptable
to said Committee are approved.
B. Smokepipes
shall not pass through partitions of combustible construction unless
they are guarded at the point of passage by metal ventilated jackets
or collars not less than twelve (12) inches larger in diameter than
the smokepipe or by equivalent protection satisfactory to the Committee
on Buildings and Grounds.
