Abstract: A factory-built fireplace having a refractory hearth floor which is supported from beneath only at the side and rear marginal edges, and is not physically connected to any fireplace structure other than a sheet metal cover plate which extends across and is supported by the front edge of the hearth. Thus, the hearth may be removed, in the event of cracking or for any other reason, and replaced simply be removing the hearth cover without disturbing other portions of the fireplace structure.

Abstract: A damper for movement between covering and uncovering positions with respect to a fireplace opening for draft control, includes a pair of rigid plates, one larger and one smaller in peripheral dimensions than the opening to be covered. These plates are carried loosely on a rod with a flexible disc, preferably of insulating material and of the same size as the larger rigid plate therebetween. The rod is movable either axially or pivotally to bring the flexible disc into and out of contact with the structure defining the opening through which draft is to be controlled.
