Syme, D C

A woodburning heating apparatus capable of horizontal and updraft combustion has removable elements positioned within a relatively small enclosed volume to provide efficient and reliable operation in either combustion mode. The removable elements include the wear plates, fireback, and damper assembly. The wear plates and fireback define primary, secondary, and night air supplies for the apparatus. An articulated damper control mechanism provides resistance against impinging combusted gases in at least one position of the damper. The damper construction allows, in either the horizontal or updraft combustion modes, the provision of both top exiting and rear exiting flue connections. Baffles are provided at the combusted gas exit from the primary combustion chamber to uniformly spread the combusted gases exiting the primary chamber over a substantial volume so that localized heating of the apparatus does not occur.
