  • Patent number: 7082942
    Abstract: A wood burner includes a wrapper. A firebox is positioned in the wrapper that defines a combustion chamber. An air inlet is placed in communication with an external air supply. The air inlet includes a conduit to conduct the external air to the combustion chamber and a second conduit. A manifold is positioned above the firebox. The manifold is in communication with the second conduit, and includes one or more manifold chambers for permitting the external air received thereby to become heated. A plurality of air tubes connect to the manifold to receive the heated external air from the manifold, each plurality of air tubes including a plurality of apertures to direct the heated external air into the combustion chamber adjacent an upper inner surface of the firebox.

  • Patent number: 5626127
    Abstract: A fireplace including a heat exchanger beneath the combustion chamber floor. The front panel or surround of the fireplace housing includes a central opening which accesses the combustion chamber. Room air inlets and outlets, which are ducted to the heat exchanger, are horizontally arranged in a duct manifold that is positioned above the front panel opening. By positioning the room air inlets and outlets within the front panel opening rather than in the surround, the entire surround can be faced with marble, brick or other decorative material without having to provide a break therein for the ingress and egress of room air. A fan within the heat exchanger circulates room air in a flow path from the room being heated into the duct manifold inlets, through a first duct and into the heat exchanger, from the heat exchanger and through a second duct, and out through the duct manifold outlets. The fireplace also includes a raiseable hearth overlaying an opening accessing the heat exchanger fan.
