Abstract
A fireplace configured for reducing the heating, and hence the temperature, of the surface above the front face of the fireplace. The fireplace includes an air management system for separating one or more relatively warm air stream from one or more relatively cool air stream. The relatively cooler air stream exiting the fireplace may be drawn by the relatively warmer air exiting the fireplace into flowing upwards along a surface above the front face of the fireplace. An insulating layer of relatively cooler air may form between said surface and the relatively warmer air exiting the fireplace.
