Abstract: There is disclosed a fireplace screen comprising a frame which fits against the fireplace opening and a pair of doors hinged at the side which substantially close the fireplace opening and are fitted with glass panes so that the interior of the fireplace is visible from the adjacent room. The fireplace doors are of substantial thickness and are provided with vertical tubes inside the glass panes which have openings at the top and the bottom of the door to permit the passage of air from the room through the tubes and back into the room again. The tubes are preferably black to make them beat absorbing at least on the side facing the fireplace with the result that the tubes become quite hot and the air passing through the tubes is significantly heated. Heating of the air causes a chimney effect so that the air is drawn in at the bottom of the tube heated and exhausted at the top of the tube.

Abstract: There is disclosed a fireplace combustion air duct including a main duct of heavy sheet metal or other refractory material suitable for the high temperature environment of a woodburning fireplace, which main duct is open at least partly along the bottom to receive air from the ash clean-out opening or other opening in the floor of a woodburning fireplace and also open at the forward end. Sliding into the forward end of the main duct is an adjustable duct open at least at the forward top portion thereof and configured to fit in telescoping fashion within the main duct. The adjustable duct is provided on the front end with a deflector plate for directing air from the duct to the rear of the fireplace so that logs or other combustible material on or directly above the duct will be directly exposed to a strong flow of air from the combustion air duct.
