ABSTRACT:
A chimney cap for diverting rain and downdrafts from a chimney while providing minimal restriction to the upward escape of chimney gases includes a base, for attachment to the chimney, and two arch-like sheet metal members attached to the base. The arches are of different heights and overlap one another over the center of the base to form a clearance therebetween for the escape of gases. The crowns of the arches are inclined in opposite directions and slope downward from the center of the cap to overlie opposite sides of the base.
