ABSTRACT:
A lightweight, prefabricated, modular masonry fireplace. The firebox is pre-cast in modular sections of lightweight vermiculate concrete. A kiva-style version of the fireplace features a modular firebox disposed within an outer facade made from a tubular steel frame, covered with metal-mesh stuccoed and plastered to present the aesthetic configuration of a sculpted adobe fireplace. An alternative, but equally desirable Rumford-style version of the fireplace does not require an outer facade, but also is assembled from lightweight modular sections.The firebox of all embodiments is cast in modular sections. A central body section of the firebox is placed upon a base, and a smoke plenum section is placed upon the central body section. The central body section, and in some embodiments a portion of the smoke plenum section, define and mostly surround the combustion chamber. The central body section may be a single integral pre-cast component, possibly including an arcuate horizontal section, or may include a plurality of pre-cast planar sections interconnected to collectively constitute the central body portion. All modular components are fashioned from lightweight vermiculite concrete; the combustion chamber is lined with split refractory firebrick or suitable cast refractory alternative. The cast smoke chamber plenum section, which may be a single pre-cast component or a plurality of interconnected modular components, stacks upon the central body to provide a transition from the masonry firebox to a double-walled chimney system.The fireplace can be placed in a room corner or in a chase on a flat wall. It can also be installed over wood floors, or on upper floors, in old or new construction.
