An auxiliary draft device is described for a fireplace to produce a curtain of air discharged upwardly in front of the fireplace opening and comprising a horizontal sheet metal air-distributing shell having fixed walls and decreasing in width from one end to the other to effect a substantially even discharge of air across said fireplace opening by air discharge openings in the top wall of the shell. The shell is supported solely by a floor adjacent the hearth of the fireplace and which, at the wider end thereof, is connected to an extension shell of sheet metal which is a plenum chamber at one side of the fireplace which communicates with a horizontal conduit extending along one side of the fireplace. Transversely to said chamber and extending through the exterior wall of room in which the fireplace is located and communicating with outdoor air, an inlet is controlled by an adjustable exterior damper operable by manual adjustment of mechanism extending from said damper to the interior of said room.
