ABSTRACT:
A combination glass door fireplace closure and heat exchanger which can be inserted into the cavity of a gas fired fireplace to permit more efficient and economical operation thereof. The insert includes a plurality of substantially parallel C-shaped exchanger tubes. The lower and upper ends of the tube are coupled to a glass door fireplace closure which is adapted for sealing the frontal opening of the fireplace cavity. A substantially C-shaped heat exchanger duct surrounds the tubes and the lower and upper ends thereof are coupled to the glass door fireplace closure. A gas pipe nozzle is mounted beneath the tubes above the heat exchanger duct and is covered by a quantity of sand supported by a tray. The nozzle pipe is coupled to a gas supply pipe extending from the side of the fireplace. Gas discharged from the pipe diffuses through the sand to produce uniform burning when mixed with air drawn through a combustion air inlet in the glass door fireplace closure. A fan blows air through the heat exchanger tubes. Air flows by convection through the exchanger duct. A first manifold structure permits air to be separately drawn into the heat exchanger tubes, the heat exchanger duct, and into the combustion area through the fireplace closure. A second manifold structure at the top of the fireplace closure couples the upper end of the heat exchanger tubes and the heat exchanger duct so that warm air is expelled therefrom through common air outlets in the fireplace closure.
