ABSTRACT:
A metal chimney construction for use with heating fixtures such as prefabricated fireplaces. The chimney is constructed from pipe sections joined together by an "inside-outside" coupling ring. The ring is formed from thin-gage sheet metal, shaped and seamed to form an integral cylindrical body. One end is dimensioned to receive the end of a first adjoining pipe section therein, the other end is dimensioned to receive the end of a second adjoining pipe section thereover. A modified coupling for coaxial, multiple-pipe installations is also disclosed.
