Abstract

A catalytic insert for an existing fireplace structure includes a frame for carrying a catalyst member. The frame is disposed in the fireplace structure at a vertically elevated position such that an upper chamber is formed in the structure, and such that at least a portion of the combustion products generated in the fireplace flow into the chamber through the catalyst member and exit the chamber into the room in which the fireplace structure is located. A support member extends from the frame to the fireplace structure bottom wall. The support member provides the main source of support of the frame within the fireplace structure. The frame and support member are adapted to be positionable in an existing fireplace structure to allow catalytic reaction of combustion products generated in the fireplace structure. The frame of the insert can also be adjustable to conform to multiple configurations of the fireplace structure.
