Stove construction

In a generally rectangular air-tight stove of the type having an access door in one wall, a generally horizontally extending floor defining the generally rectangular firebox, the improvement comprising air inlet valve means provided in said door and including at least one threaded member threadably received in a lower region of the door and adapted to meter inlet air through associated openings, a baffle plate mounted to the inside of the door and having a lower region defining a series of primary air outlets arranged laterally across the width of the door mounted baffle plate, said baffle plate having an integrally defined peripheral flange adjacent the sides and bottom of the door but spaced from the top of said door to define a top opening therebetween, a chevron shaped baffle wall above said primary air outlets, said baffle wall and peripheral flange abutting said door to define a primary air chamber between the door and said baffle plate, and openings defined at opposite ends of said baffle wall to provide air flow into a secondary air chamber defined between the door and said plate above the chevron shaped baffle wall, a horizonal baffle wall above said chevron shaped baffle wall and defining the upper boundary of said secondary air chamber and secondary air outlets in the baffle plate to provide secondary air to the interior of the stove structure through said secondary air outlets above said primary air outlets said horizontal baffle wall having its ends spaced from said peripheral flange to provide air passages communicating with said top opening.
