A. For Domestic Gas-Fired Appliances. Domestic gas consuming devices
may be vented to special flues when such special flues are of type
listed and approved by the Underwriters' Laboratories, Inc. or a similarly
recognized testing laboratory and satisfactory to the Building Inspector;
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 the Building Inspector.
B. For Domestic Appliances Fired With Coal, Oil, Wood Or Gas. Heating
appliances fired with coal, oil, wood or gas, may be vented to special
flues in lieu of the above when such special flues are of a type listed
and approved for such use by the Underwriters' Laboratories, Inc.,

shall be used unless the overall thickness is twelve (12) inches.
B. Fireplaces shall have hearths of brick, stone or other approved incombustible
material supporting 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 least four (4) inches from the back of a fireplace. Such spaces
shall be firestopped with noncombustible material.
[Ord. No. 687 §306, 11-1-1960]
A. Heating appliances shall not be mounted on floors of combustible
construction unless they are either approved by the Building Inspector
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
of 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 appliance, 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

combustible material, whether plastered or not.
B. Ranges, stoves, heating furnaces, and similar heating appliances
and smoke pipes 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 Building
Inspector shall approve. Where a durable form of noncombustible heat
insulating protection is applied to the appliance or to the combustible
material, installation may be made with lesser clearances as the Building
Inspector may approve.
[Ord. No. 687 §308, 11-1-1960]
A. Every smoke pipe shall connect with a chimney or other approved flue.
No smoke pipe shall pass through any floor, ceiling, roof or wall

ventilated jackets or collars conforming to recognized good practices
and acceptable to the Building Inspector are provided.
B. Smoke pipes 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 smoke pipe or by equivalent protection satisfactory to the
Building Inspector.
