A fireplace having a bottom wall, inner top wall, two side walls and rear wall defines a combustion chamber having a front opening. An outer top wall is disposed above the inner top wall. The outer top wall and the inner top wall are disposed in spaced apart relationship relative to each other and define an air flow channel therebetween having an inlet. The outer top wall is an upper exterior surface of the fireplace and includes a first nozzle member. The inner top wall is an upper interior surface of the combustion chamber and includes a second nozzle member. A chimney flue is attached to the outer top wall. The first and second nozzle members are in fluid communication with the chimney flue and define a converging nozzle therebetween inducing a flow of cooling air in the air flow channel.
