Abstract From the Canadian patent

An ash pan assembly for a wood burning or coal burning stove includes an ash pan door permanently attached to the stove and mounted for movement between a closed ash collection position and an open position. An ash pan is mounted to the movable ash pan door. A detachable ash pan cover is easily attached to the ash pan in the open position. The ash pan cover prevents accidental spillage of ashes and hot coals from the ash pan and includes a carrying handle by which the ash pan is lifted from the assembly and taken for disposal. The ash pan door is preferably hinged to the front wall of the stove for swinging to the open position.
