First Claim
Patent Images
1. A fireplace assembly comprising:
- a combustion chamber having a forwardly facing optically transparent wall;
a second optically transparent wall spaced from said combustion chamber wall defining an air passageway;
an intake air vent disposed above said combustion chamber in communication with said air passageway; and
an exhaust air vent disposed internal to said intake air vent and being in communication with said combustion chamber;
said air passageway being in communication with a bottom of said combustion chamber;
wherein intake air is drawn downwardly from said intake air vent through said passageway thereby exchanging heat from said optically transparent walls to said intake air and said intake air flows into the bottom of said combustion chamber combining with fuel in said combustion chamber to form combustion byproducts which are exhausted from said combustion chamber through said exhaust air vent.

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.
