Abstract: A stove having automatic chimney air flow compensation for reductions in air flow to its combustion chamber is disclosed. An increase or decrease in compensatory air flow is dependent upon the movement of ganged dampers. The amount of compensatory chimney air flow is dependent upon the size and/or position of apertures and blocking portions formed respectively in the ganged dampers. The dampers can be configured, as appropriate, and thereby tuned, to be particularly responsive to local conditions.The stove is provided with a conduit positioned to provide a source of fresh air. The conduit is clamped to the stove to heat the air flowing therein and thereby prevent exhaust gas condensation and creosote buildup when it rises in and from the chimney.
