ABSTRACT:
A new fireplace assembly is provided which is inserted into a conventional fireplace and which is capable of greatly increasing the burning efficiency and heat output over conventional units, decreasing the waste heat lost and at the same time providing a unit which is as pleasing from an aesthetic standpoint as a conventional fireplace. The assembly of this invention includes a firebox in which combustion is maintained and mounted on the hearth of a fireplace, the firebox having doors in the front thereof opening into the combustion chamber, the doors having adjustable draft means therein to control the amount of air introduced to support combustion, a smoke outlet box mounted on the rear of the firebox and extending into the fireplace opening, the firebox having controllable damper means for conveying smoke from combustion to and up the chimney of the fireplace. The opening into the smoke outlet box is at least partially covered by a spark shield. A smoke shelf is provided which protrudes from the front of the firebox substantially horizontally into the combustion chamber. The spark shield and smoke shelf cooperatively coact to provide enhanced heat circulaton. An optional water trough located at the top of the firebox is provided into which water can be placed to increase humidity in the surrounding air.
