Abstract
A heating apparatus for operating in one or the other of two combustion modes has a frame assembly enclosing a primary and secondary combustion chamber. A baffle, separating the chambers, provides for gaseous communication therebetween. Preheated primary and secondary combustion air is directed in a controlled fashion to the front of the frame assembly across a viewing window to keep the window clear. The apparatus further has an off center damper movement system, means for defining a secondary air flow path through the primary combustion chamber, and a structure which can be changed for operation either as a wood burning or a coal burning stove.
