Abstract

A chimney top assembly adapted to be mounted to the exit end of a chimney flue of the type utilized for fireplaces. The chimney top assembly allows hot combustion gases to escape through the assembly with the least resistance to its flow while providing maximum resistance to rain entry into the chimney flue. The assembly includes a divergent nozzle having a flared open outer end and an open inner end which is adapted to be coupled to the exit end of the chimney flue. The flared open outer end diverges at an angle from the axis of the chimney flue insufficient to cause separation of flue gases exiting therefrom and a baffle or rain cap is mounted at a predetermined spaced distance above the open outer end of the divergent nozzle whereby a significant portion of the energy normally lost by flue gases exiting from the chimney flue is recovered. The use of such an assembly decreases the possibility of fireplace smoking, increases the safety of the fireplace system, and allows the use of a smaller diameter more compact piping system.
