Abstract
Door structure is provided for a wood-burning stove which is less susceptible to warping in use than a conventional flanged stove door opening. The door opening is formed by a process of cold drawing or extruding a rounded lip or flange which is integral with the stove front plate. Internal door structure provides angulation of the door with respect to the stove front plate.
