ABSTRACT:
A positive interconnect system (10) embodying the concepts of the present invention provides a sealed passageway between a fireplace insert (11) and a liner (12) in the flue (13) of a chimney (14). An oval connector (46) and a transitional connector (48) are each constructed with an overall depth dimension such that they may be individually inserted through the opening (29) in a damper frame (21) and into the smoke chamber (28) of the chimney (14). After the connectors (46, 48) are received within the smoke chamber (28) they may be joined together by an interlock (49) to form a composite connector assembly (45). The assembly (45) is then fastened to the uppermost end (95) of a flexible duct (40), and the assembly (45) is then moved upwardly through the smoke chamber (28) into sealing engagement with the flue liner (12). Post means (111, 112) support the assembly (45) in sealing engagement with the flue liner (12). The lowermost end (110) of the flexible duct (40) is operatively connected to an insert connector (35), and the insert connector is secured to the insert (11) by a selection of inside or outside fastener means (135 or 136). The insert connector (35) is provided with a boot (120) that is adjustably positionable with respect to the frame (121) of the insert connector (35).
