Existing chimneys and vents. Where an appliance is permanently disconnected from an existing chimney or vent, or where an appliance is connected to an existing chimney or vent during the process of a new installation, the chimney or vent shall comply with Sections 801.18.1 through 801.18.4. Where a new or replacement vented appliance is approved for use in connection with an existing chimney not currently in use, compliance with Section 801.18.5 is required.
[No change to Sections 801.18.1 through 801.18.4 of the International Mechanical Code]
Insert a new Section 801.18.5 into 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 not currently in use, 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 D.C.-licensed contractor who conducted the inspection or test.
