The provisions of this subsection shall not apply to smoke, the shade or appearance of which is equal to but not darker than No. 3 of the Ringlemann Chart for a period or periods aggregating five (5) minutes in any thirty (30) minutes, when building a new fire, cleaning flues or when breakdown occurs such as to make it evident that the emission was not reasonably preventable.
