ABSTRACT:
A chimney by-pass is disclosed for use with a main chimney. In case of a chimney fire, a movable damper closes off the main chimney, substantially reducing the severity of the chimney fire. The movable damper also opens an auxiliary chimney, allowing smoke to exit, uninterrupted through the auxiliary chimney, and may include a fan to assist the exit of smoke into the atmosphere. The movable damper may be actuated manually or automatically in case of a chimney fire.
