Abstract

A fireplace assembly of the type used as a room air heater comprises a second pane of glass in front of and spaced from the glass pane forming the front of the combustion chamber. The two panes form an air passageway for delivering intake air from an upper vent to the bottom of the combustion chamber. The intake air cools the panes of glass such that a relatively inexpensive glass material can be used and such that the front of the fireplace assembly is relatively cool to the touch.
