ABSTRACT:
A pre-built fireplace has a housing with an outlet for combustion gases and an open front for viewing the inside of the fireplace. A hinged damper and a hinged lintel extension are suspended from the inside of the fireplace. The damper and lintel extension are pivotally secured to each other so that when the damper is open, the lintel extension is in place to deflect combustion gases, and when the damper is closed, the lintel extension is pivoted substantially out of view.
