(a) Where an application has been filed it shall be the responsibility of the inspectors of plumbing to see that gas-fueled space and water heaters are installed in dwellings, apartments and rooms where such heaters are permitted to be installed in lieu of central heat or supply of hot water. They shall see to it that the appliances are of types approved by the Department of Buildings and the American Gas Association, and are installed in compliance with these rules.
(b) An application covering the installation of these appliances in dwellings shall be forwarded directly to the plumbing inspectors when approved as a permit. The installation of such appliances including Type B and other gas vents, but not chimneys, shall be inspected by inspectors of plumbing. If an application does not call for construction of a masonry or metal chimney, it shall be reported as completed, by the plumbing inspector, provided the work was satisfactory with a note on his report "no structural work."
(c) If the application calls for the erection of a masonry or metal chimney, it shall be forwarded by the plumbing inspector to the construction inspector as soon as the plumbing inspector has found the installation of these gas appliances and vent connections satisfactory. The construction inspector shall report such an application completed if the construction of the chimney has been satisfactorily performed.
