(A) The construction, arrangement and manner of installation of all gas burners and gas burner equipment hereafter installed for use in connection with heating systems, and the alternation and repair hereafter of all gas burners and gas burner equipment used or to be used in connection with heating systems, shall conform to the provisions of this subchapter.
(B) With the enactment of this subchapter, a list of gas-fired burners and equipment shall be maintained by this Department which, through the arrangement of parts, suitability of materials, strength of parts, electric or other controls, thermostatic arrangement, reliability of automatic features, positiveness of ignition and possibility of explosion, have been found by test or acceptable proof from the American Gas Association or other nationally recognized laboratory, to be acceptable under the provisions of this subchapter.
(C) It shall be unlawful for any person, licensed to install, alter, repair or replace gas burners within the city, to install any used gas burner or for the Inspector to issue any permit authorizing him or her to do so, until said licensee shall have first submitted with his or her application for such permit a copy of the purchase order describing the used burner that is to be installed and a statement by the purchaser acknowledging that to be the case, together with a statement by said licensee that said burner has been properly reconditioned and will comply in every way with code requirements for new equipment as to operation, safety standards and adjustments.
(D) No gas burner shall be installed in a room in which the facilities for ventilation do not permit the proper combustion of gas.
(E) The gas cock or shutoff for a gas burner shall be easily accessible.
(F) On conversion burner installations, the gas supply cock shall be located approximately five feet above the floor and approximately two feet to the rear of the face of the furnace where practicable.
(G) (1) When air or oxygen under pressure is used in connection with any gas supply, effective means shall be provided to prevent the air or oxygen from going back into the gas piping.
(2) Power burners (gas-air mixture furnished by a power blower) shall be equipped with an interlock control that will shut off the gas supply to the burner in the event of failure of the air supply to the burner (controls actuated by failure of power supply to the blower motor do not meet this requirement).
(3) All gas burners shall be located so that they will be readily accessible for operation, repair and adjustment and for maximum safety.
(4) Gas burners shall be installed so that their continued operation will not raise the temperature of surrounding combustible materials or construction more than 90°F above normal room temperature.
(H) Equipment with closed bases, in which no provision is made for the circulation of air below the burner boxes or combustion chambers shall be properly insulated from combustible floors.
(I) The minimum clearance of gas-fired heating units from combustible partitions and materials shall be as set forth in the Michigan Mechanical Code and Building Code except, in the case of equipment especially designed for burning gas and tested and listed for lesser clearance by a nationally recognized testing laboratory.
(J) The clearance to combustible construction may be reduced as specified in the Michigan Mechanical Code and Building Code where the combustible construction is protected.
