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. The combustion air duct is preferably provided with arms on the sides of the main duct which together with the main duct act as fire dogs for logs and do away with the necessity for any other fire dogs or log basket for the fireplace. The main duct is also preferably provided with a low barrier at the forward end to prevent ashes or coals from falling into the opening at the front of the combustion air duct.
