Abstract
Disclosed herein is an improved wood burning stove employing a combustion chamber and a flue for removing exhaust therefrom and also a catalytic converter means for oxidizing oxidizable species in the exhaust. A passageway is provided for bypassing the exhaust around the catalytic converter means, the passageway being controlled by a bypass damper for controlling access to the passageway for varying impedance otherwise presented to the exhaust by the converter, for example, during the addition of fuel to the stove. Such an arrangement minimizes back pressure caused by the converter means.
