Abstract
A chimney liner system for insertion into a masonry chimney from the top of the chimney down to a stove or fireplace insert. If an offset or a chimney shelf exists in the chimney, a flexible metal pipe member is connected to the bottom end of the chimney liner system. A ceramic heat resistant cloth formed as a sleeve encloses the flexible metal pipe member in selected systems, and in some systems, the sleeve encloses the entire chimney liner system. In some applications, the sleeve may be made from a fiberglass cloth sewn or connected to an inner blanket insulation.
