Abstract: An airtight steel stove having a dripless top or rear flue collar and cover plate assembly is disclosed. The stove is provided with similar openings in a top wall and a rear wall. Interchangeable flue collar and cover plate assemblies allow the stove to be used either as a top flue or rear flue type by placing the flue collar and cover plate assemblies as desired. The flue collar has an inside diameter sized to receive a stove pipe therewithin. This eliminates drippage of creosote and other similar products of combustion onto the outside of the stove. Instead, such materials are returned to the interior of the stove.
