ABSTRACT:
A clip-on chimney hood comprising a substantially circular, oval, or inverted U-shaped spring integrally attached to a hood. A preferred material for the spring is a utility cable which can be formed into a loop by slipping each of the loop ends, of a length of cable, into a short metal sleeve and then welding or brazing. Either a single or double loop is attached to a hood which may be either corrugated or of flat sheet metal extending at right angles to the loop or loops. The spring loop or loops are inserted into the chimney, or a chimney liner, and frictionally held therein. The distance between the hood and top of the chimney or liner, may be easily adjusted simply by detaching a few wire fasteners at the lower edges of the hood which allows the hood edges to always rest on the chimney for added stability. Maximum hood opening accommodates coal or wood burning while minimum opening accommodates gas or oil burning. Since the chimney hoods are simply clipped onto the chimney, no fastening elements are needed and easy adjustability is provided.
