A novel dual mode of operation gas fireplace of the type having a combustion chamber box and a heat exchanger is provided with a burner in the bottom of the combustion chamber box which creates exhaust gasses to be passed out of the combustion chamber box and into or through the heat exchanger portion of the fireplace mounted on top of or back of the combustion chamber box. The hot exhaust gasses leaving the combustion chamber box may be directed into an exhaust stack or diverted directly into the room to be heated by a blower motor which diverts hot exhaust gas products from the heat exchanger directly into a room area to be heated in a ventless mode of operation. When the blower motor which diverts the exhaust gasses into the room is deactivated, the novel fireplace may be operated in a vented mode of operation. The feature of the present invention is that the novel fireplace may be operated in both the dual modes of operation simultaneously to achieve greater efficiencies than could be achieved by operating the fireplace in a vented mode of operation alone.
