Abstract
A solid fuel burning space heating appliance comprises a combustion chamber including front, side and rear walls, a top and a bottom. An apertured grate arrangement is provided in the combustion chamber for supporting solid fuel. An ash collecting region is located under the grate arrangement, with an air inlet for providing combustion air. A first air outlet in the combustion chamber is located below the grate arrangement, and a second air outlet in the combustion chamber is located above the grate arrangement. An air diverting arrangement is provided for selectively diverting air from the air inlet between the first and second air outlets. A glass cleaning system provides a vertical curtain of air over the interior surface of a glass panel. The glass cleaning system includes an air supply adjacent one side wall, an air reservoir connected to the air supply and a dam defining a tapered outlet slot for providing the curtain of air from the air reservoir. A tangential-flow fan is located between the combustion chamber and an outer casing. An air duct extends from the front of the appliance to the ends of the fan for cooling purposes.
