(A) Materials. Chimneys shall be constructed of brick, stone, or reinforced concrete or hollow masonry units. When built of reinforced concrete or hollow masonry units with walls less than eight inches thick, the chimney shall be lined throughout the flue linings. Pre-fab chimneys may be used, such as Metalbestos chimney for oil or gas or any other pre-fab with the same fire rating.
(B) Foundations. Chimneys shall not rest upon or be carried by wood floors, beams or brackets, nor be hung or supported by metal stirrups from wood construction but shall be built upon concrete or masonry foundations or reinforced concrete slabs properly proportioned to carry the load without danger of settlement or cracking. The footing shall rest on solid earth and shall be carried below the frost level.
(C) Separation from other construction. No combustible beams, joists or rafters shall be placed within two inches of the outside face of the chimney. No combustible studding, lathing, furring or plugging shall be placed against a chimney or in the joists thereof.
(D) Flashing connections. Flashing connections between roofs and chimneys shall be made with cap and base flashings of sheet metal or other approved material.
(E) Height. The chimney shall be built at least two feet above the highest point of the roof.
(F) Use. All flame type heating devices or appliances used for space heating shall be safely connected with a chimney and shall be subject to the approval of the Code Administrator.
