Abstract
A fireplace draft control useable in fireplaces having air inlets in either the floor or rear of the fireplace. The device comprises a base having punchout section which may cooperate with an air opening in the fireplace floor. A slidable plate is used for covering this opening. A hood, having openings to direct air to the fireplace grate, is attached to the base. A hinged plate is provided at the bottom rear portion of the hood to cooperate with an outside air source entering through the rear of the fireplace. A control rod is connectable to either the slidable plate or the hinged plate. A second punchout may be provided in the base to cooperate with a separate ash dump opening.
