(A) Ventilation shall be provided to prevent the accumulation of any trapped vapors below the combustion chamber. Rooms in which oil-burning equipment is located shall be provided with adequate ventilation to assure continuous complete combustion of the oil.
(B) Name-plate designating the trade-name of the burner, the model or size number and the name and address of the burner manufacturer shall be securely attached to each fuel oil-burner and oil-burning space heater.
(C) No damper shall be permitted in the smoke pipe or chimney from the device heated that may restrict the passage of fumes or gasses by more than 40%. Each oil-fired heating unit covered by this subchapter shall be connected to a chimney flue.
(D) (1) Chimney flues and flue pipes shall freely conduct the flue gases to the outer air. The chimney or flue shall be properly constructed in accordance with the requirements of Ch. 154.
(2) The flue pipe shall not enter the chimney or flue beyond its inner wall and shall be so cemented to the chimney as to prevent infiltration of air. In entering the chimney or flue, the connection shall be made at least six inches above the extreme bottom.
(E) (1) The vent connection shall not be smaller than the size indicated by the vent collar of the appliance when same is oil designed.
(2) The horizontal vent connection shall not be longer than one-half the effective height of the chimney. The vent pipe shall maintain a pitch or rise of one-quarter inch per foot of the horizontal run from the equipment to the flue or chimney.
(3) The vent pipe shall be so installed as to avoid sharp turns or other constructive features which would create excessive resistance to flow of the gaseous products of combustion.
(4) Vent pipes from one or more oil-fired space heating appliances may be interconnected provided that the cross-sectional area of the manifold shall be equal to the sum of the cross-sectional area of the manifold shall be equal to the sum of the cross sectional areas of the vent collar connections of the appliances.
(5) No vent from an oil-fired space heating appliance shall be interconnected with a vent pipe from an appliance burning other fuels or designed for other uses except with the specific approval of the Department.
(6) A vent pipe from an oil-fired heating appliance and vent pipes from other appliances, burning the same or other fuels, may be connected into the same chimney through separate openings located at different levels, provided that the operation of any of the equipment is not adversely affected.
(7) The material used for vent pipes shall be such as to resist the corrosive action of flue gases and condensate.
