The specification discloses a prefabricated factory built fireplace for on site installation with a dual opening hearth. The fireplace has a firebox disposed over the hearth which is formed of two upstanding sidewalls with front and rear panels disposed therebetween. Each panel defines a relatively large rectangular opening for providing front and rear access to the hearth. A hood, disposed above the hearth and connected to the firebox, defines a flue in the top portion thereof for venting combustion products of the firebox into the chimney. The sidewalls of the firebox and the hood are formed of a triple insulated wall structure containing an outer, intermediate and inner casing. The outer casing is separated from the intermediate casing by insulation material and the intermediate casing is separated from the inner casing by an air passageway which communicates between the inside of the firebox and the flue.

DETAILED DESCRIPTION The present invention is directed to providing a suitably insulated and properly ventilated, factory built, dual opening hearth fireplace.
In accordance with one aspect of the present invention, a prefabricated fireplace has a firebox disposed over a hearth and formed of two upstanding sidewalls with front and rear panels disposed therebetween, each panel defining an opening to provide front and rear access to the fireplace.
A hood, disposed above the hearth, is connected to the firebox for venting combustion products to a chimney.
The hood and sidewalls are formed of a triple insulated wall structure containing an outer casing, an intermedmiate casing and an inner casing.
The intermediate casing is separated from the outer casing by insulation material and separated from the inner casing by an air passageway communicating between the chimney and internally of the firebox to provide ventilation and insulation of the firebox.
