Heating apparatus with fan

Abstract

A heating apparatus can have a sealed combustion chamber, a burner, and various air channels to direct air into the sealed combustion chamber and to provide heated air to the desired area or environment such as an interior room. A channel can direct a flow of air along a face of the sealed combustion chamber to cool the face. The channel can be within or outside of the sealed combustion chamber. Alternatively, or in addition, the heating apparatus can be capable of operating as a direct vent device or as a vent free device.

What is claimed is: 
     
         1 . A gas fireplace assembly comprising:
 a sealed combustion chamber, having a front face viewable to a user when the fireplace is in use;   a burner disposed within said combustion chamber;   a combustion air inlet in fluid communication with the sealed combustion chamber and configured to provide air to the burner;   an exhaust air outlet in fluid communication with the sealed combustion chamber and configured to remove exhaust air from the combustion chamber;   an outer housing surrounding at least a portion of the sealed combustion chamber;   a ventilation air inlet;   a ventilation air outlet;   a first air conduit positioned within the outer housing and configured to draw air into the first air conduit through the ventilation air inlet and to expel heated air out through the ventilation air outlet, the first air conduit being in sufficient proximity to said sealed combustion chamber that air within said first air conduit is heated by said sealed combustion chamber;   a combustion chamber front face air outlet positioned near the front face and configured to direct air from within the outer housing outside of the fireplace along and toward the front face of the sealed combustion chamber; and   a first fan positioned within the outer housing configured to direct air through the combustion chamber front face air outlet along and toward the front face of the sealed combustion chamber to thereby cool the front face.
