Abstract
A fireplace and top wall assembly is disclosed. The top wall assembly includes primary and secondary aligned flue outlet assemblies that form between them a primary air conduit and a secondary flue gas conduit. Both of the conduits are designed to be mounted in fluid communication with the inlet opening of a chimney flue of a fireplace. Flue gases are drawn from the combustion chamber of the fireplace through the secondary flue gas conduit to mix air drawn in by the primary air conduit to promote cooling of the top wall assembly and surrounding fireplace structure.
