§40-15 Issuing Approvals

   (a)   A gas-fueled space or water heater installed after December 18, 1957, and a gas-fueled space heater installed prior to that date, in the residence portion of a multiple dwelling and installed after October 1, 1964, in one and two family dwellings, shall be approved by the Department of Buildings only if it is of a type approved by the Department of Buildings and the American Gas Association, and if it has been installed in compliance with these rules. A gas-fueled water heater installed in a multiple dwelling prior to December 18, 1957, and in a one or two family dwelling prior to October 1, 1964 shall be approved by this department only after it has been made to comply with all the requirements of these rules. The certification of approval of type of appliance by the Department of Buildings of such water heaters shall be attached to the application.

   (b)   An application which has been filed to cover the installation of only gas-fueled space heaters or only gas-fueled water heaters shall be reported as being satisfactorily completed only if all apartments in the building have been provided with either space or water heaters as the particular application specified. If an application calls for the installation of both space heaters and water heaters it shall be reported as being satisfactorily completed only if all apartments in the building have been provided with both space heaters and water heaters. Nor shall any application be reported as being satisfactorily completed unless all new appliances have been installed in compliance with these rules and all existing appliances have been made to conform with them.

   (c)   When the plumbing section signs off, as satisfactorily completed, an application which provides for the installation of gas-fueled space heaters in all apartments of a multiple dwelling, including the apartments where gas-fueled space heaters may have been installed prior to December 18, 1957, they shall make a list of such premises and send a copy of the list to the Department of Housing Preservation and Development. Where water heaters also have been satisfactorily installed, that fact should be noted on the list. The list shall contain the premises and the application number under which the appliances have been installed, and shall be forwarded weekly.
