Abstract
A fireplace comprised of a burning chamber having an opening to a room and a vertically lifting door having a top edge, a bottom edge and opposing side edges. The door narrows in width from the top edge to the bottom edge to provide a keystone-shaped door. A frame is fitted in front of the burning chamber. The frame includes guide tracks configured to accept the edges of the door. A drive mechanism is provided to raise and lower the door within the guide tracks. The guide tracks may further incorporate a high temperature gasket to prevent airflow and promote energy efficiency when the door is closed.
