ABSTRACT:
A fireplace has a manifold positioned between a combustion chamber and a flue. The manifold has a pair of inlets to supply dilution air to the flue, one extending from a front face of the fireplace, and the other from a rearward location. A baffle extends across the outlet of the manifold to prevent direct communication between the combustion chamber and flue. The inlet at the front face enables the flow of dilution air to be checked with the fireplace installed without having to accomodate the full flow of dilution air. The baffle prevents downdrafts from adversely affecting the combustion in the combustion chamber.
