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.

In a stove having a combustion chamber including a lower zone for burning combustibles therein, an access opening for inserting combustibles therethrough into the combustion chamber, and at least one access door for normally closing the access opening, the combination therewith of means defining a smoke passage extending along an upper portion of the stove above the zone for burning combustibles in the combustion chamber and having a rear portion adapted to communicate with a chimney for exhausting the products of combustion from the combustion chamber, said smoke passage having a main opening and an auxiliary opening therein for communication with the interior of the combustion chamber, regulator damper means associated with said smoke passage for normally adjustably restricting the flow of the products of combustion from the combustion chamber through said main opening and said smoke passage to the chimney, auxiliary damper means normally closing said auxiliary opening, said main opening being located adjacent the stove access door so that heated air and products of combustion normally flow in a generally sinuous path toward the access door and then upwardly and away from the access door and into said main opening, said auxiliary opening being located substantially further away from the access door and more closely adjacent the rear portion of the smoke passage than said main opening, and means operably associated with said auxiliary damper means and the stove access door for effecting movement of said auxiliary damper means from the normally closed position to the opened position prior to the access door being opened for redirecting the products of combustion through said auxiliary opening and thus further away from the access door so as to thereby prevent the escapement of smoke through the access opening when the access door is opened.
