Anatomy of a Fireplace
While there are differences among the various types of fireplaces, there are several common parts. An understanding of the basic terminology will help make your fireplace both safer and more enjoyable.

Ash Pit A cavity underneath a fireplace firebox, used as a receptacle for ashes, and accessible for cleanout by means of a cleanout door.
Ash Pit Cleanout Door A metal door located at the base of the chimney which leads to the ash pit, facilitating cleanout of the ash pit.
Damper A plate or valve that closes the fireplace flue when the fireplace is not in use. You must fully open it before lighting the fire.

Firebox This is where you build the fire.
Flue The vertical passageway up the inside of the chimney.
