Abstract
Abstract This is a stove primarily for the burning of wood, but also capable of burning other combustible materials, which stove is characterized by a unique combustion chamber, together with a recirculating combustion chamber and baffle for more perfect combustion and characterized by a heat radiating chamber which may be closed so as to be used as an oven, and by a unique damper placement in combination with the exhaust flue pipe so adapted as to automatically activate in order to cool the flue pipe in the event it should exceed safe heat limits.
