(A) Except as herein provided, all chimneys in every building hereafter erected and all chimneys hereafter altered or rebuilt shall be constructed of brick, stone or reinforced concrete or UL listed Class A chimney. No masonry chimneys shall have walls less than four inches in thickness and all chimneys shall be limed on the inside with fire clay chimney tile set in portland cement mortar. The lining shall be continuous from the bottom of the flue to its extreme height. No chimney shall be corbeled out more than six inches from a brick wall and such corbeling shall consist of not less than five courses of brick, unless the chimney shall not be corbeled out to such extent that the center of gravity of the chimney would be located so as to endanger the structure.
(B) All chimneys shall project at least three feet above the point of contact with a flat roof or two feet above any roof surface within ten feet horizontally off the chimney. Portland cement may be used in the construction of chimneys with the addition of not more than 10% by volume of hydrated lime. No chimney in any building shall have wooden supports of any kind. Supports shall be noncombustible and shall rest upon the ground or foundation walls. Concrete footings under new chimneys shall be as hereinbefore specified in the BOCA National Building Code, as now adopted or hereafter amended by the borough, for concrete footings under foundation walls.
(C) The fire-back of every fireplace hereafter erected shall not be less than eight inches in thickness of solid brickwork, or air cell construction, nor less than 12 inches of stone lined with fire brick. When a grate is set in a fireplace, a lining of fire brick at least two inches in thickness shall be added to the fireback, or soapstone, fireclay, or cast iron may be used if solidly backed with brick or concrete. All smoke pipes shall enter the chimney through a flue thimble or its equivalent such that the construction shall make a fire-tight joint with the chimney tile flue liner.
(D) All flue holes when not in use shall be closed with tight-fitting metal covers. No wooden beams or joists shall be placed within one inch of the outside face of the chimney or flue whether the same be for smoke, air or any purpose, except for hot air flues for heating purposes. No wood work shall be within four inches of the back wall of any fireplace except if a chimney is built such that the thickness from the flue line is eight inches or more. Necessary wood work may be placed against the chimney by using noncombustible material between and around the wood so placed with the approval of the Building Inspector.
