  • Liner adaptor for chimneys
    Patent number: 6852023
    Abstract: A chimney liner adaptor is provided to allow air to flow between the outside environment and an annular space in a lined chimney flue. The adaptor may allow an air cooling system to operate but prevents undesirable elements from entering the annular space. The liner adaptor may be disposed between the chimney cap and the top walls of the chimney system and around the chimney liner. The adaptor may include perforated material, such as an expanded metal mesh, a metal screen, stamped metal screen, rugged netting, or the like. The perforated material permits gas flow, provides structural support for other elements of the adaptor, and filters out undesirable objects from entering the chimney.
