ABSTRACT:
A fuel-fired fireplace insert has a compact combination heat exchanger/draft hood structure extending interiorly along its top side and opening outwardly through an upwardly extending flue gas outlet and a dilution air inlet disposed on a top front side portion of the insert. During insert operation, hot combustion gas generated within its fire box portion flows upwardly into the interior of the heat exchanger/draft hood structure, is cooled by room air entering the dilution air inlet, and is discharged through the flue gas outlet. At the same time, room air enters the insert through an opening on a lower front side thereof, is heated by being passed externally along the fire box and the combination heat exchanger/draft hood structure, and is then discharged from the insert back into the room through openings adjacent the dilution air opening.
