Abstract
A stove of the wood burning type is provided with a smoke passage having a main opening adjacent the access door of the stove and an auxiliary opening therein which is located further away from the access door and more closely adjacent the rear portion of the smoke passage and the chimney than the main opening. A regulator damper controls the rate of flow of products of combustion from the combustion chamber through the main opening and the smoke passage to the chimney, and an auxiliary damper normally closes the auxiliary opening when the access door is in a normally closed position. Apparatus is operably associated with the auxiliary damper and the stove access door for effecting movement of the auxiliary damper from the normally closed position to the opened position prior to the access door being opened for redirecting the products of combustion through the auxiliary opening and thus further away from the access door so as to thereby prevent the escapement of smoke through the stove access opening when the access door is opened.
