Abstract
A firebox for a stove is defined by top, bottom, side and end walls and employs a loading door in one of the end walls. A main draft opening associated with an adjustable damper control is provided adjacent the lower portion of the firebox and an auxiliary draft opening associated with an adjustable damper control is provided adjacent the top portion of the firebox. In a preferred arrangement the main and auxiliary draft openings are disposed adjacent one of the end walls. Also, in a preferred arrangement, the auxiliary draft opening is disposed upwardly within at least the upper one-third of the firebox. The particular structure of the stove facilitates good combustion for heating but at the same time provides an efficient shut-down condition that will maintain a small holding fire without causing creosote to build up in the flue. The main draft opening is associated with a movable door arranged to be forced open in the event of pressure being developed in the firebox.
