Ash Dump/Ash Cleanout Doors

Older fireplaces have an ash dump door inside the fireplace that enables the homeowner to push the burned ashes into a space under the fireplace. This ensures there are no hot ashes left inside the firebox overnight. 

The ash cleanout door is a corresponding ash cleanout door on the exterior of the chimney that allows access to this area to clean out the buildup of cooled ashes.
