Insert new Section 801.18.5 in the Mechanical Code to read as follows:
Integrity inspection. Before a new or replacement vented appliance is approved for use in connection with an existing chimney, the chimney shall be relined or shall be inspected for integrity by the permit holder, in the presence of the code official, using a scented smoke test or other approved method. In lieu of observing the test, the code official is authorized to accept a certification of integrity of the chimney, issued by the licensed contractor who conducted the inspection or test.
