Abstract
A novel dual direct vented fireplace includes a combustion chamber having two permanent exhaust outlets including a horizontal exhaust outlet and a vertical exhaust outlet. A fireplace enclosure surrounds at least the top, bottom and back of said combustion chamber forming three hollow plenum walls around the combustion chamber. A fresh air duct in the top and back plenum walls connects to a combustion air passageway under the gas burner system. Two permanent air inlets in said fresh air duct include a horizontal air inlet and a vertical air inlet. A coaxial pipe is provided for connection to at least one of said exhaust outlets and one of said air inlets. The other of said exhaust outlets and air inlets is covered with a closure whereby the dual direct-vented fireplace is assembled at the factory or in the field as either a horizontal or a vertical direct vented fireplace.
