ABSTRACT:
A positive interconnect system (10) for a fireplace insert (11). The primary portion (10A) of the interconnect (10) incorporates a support frame (30) that is suspended from the damper frame (12) by a plurality of non-extendable hangers (39, 40, 41 and 42). Wholly separate and distinct means (83 and 84) are provided to support the connector duct (82) and sealing means (80, 94) from the support frame (30) in order to enhance the fore and aft as well as the lateral adjustability of the primary portion (10A) of the system. Slidable collar means (115) provide selective connection with the vent (75) of the insert (11). A secondary portion (10B) communicates through the smoke chamber (26) between the primary portion (10A) and the flue (22). An adaptor boot (200) seals around the mouth (201) of the flue (22) and converts the cross-sectional dimension of the flue to the cross-sectional dimension of the duct system (202, 251, 258) that extends between the adaptor boot (200) and the damper frame (12). Means (223, 224) are provided to manipulate the adaptor boot (200) into operative position and thereafter wedge against the shelf (25) forming the floor of the smoke chamber (26) to support the secondary portion (10B) in its operative position.
