(1) The Flue is the passageway for smoke & fumes. Clay tiles or stainless steel liners provide a barrier which prevents smoke, fumes and soot from being absorbed into the masonry chimney.

(2) Smoke Chamber is the area above the fireplace and below the flue used to allow smoke to mix and rise into the flue. Because smoke tends to linger here, large deposits of creosote often accumulate.

(3) Smoke Shelf helps collect small amounts of rain that may enter the chimney. Considerable creosote deposits may collect here. The hinged plate shown is the Damper which is used to close the chimney when the fireplace is not in use.

(4) Fireplace is where the fire is built.

(5) Ash Pit is a passageway into which ashes may be emptied.

(6) Lintel is a piece of metal that supports the face wall.

(9) Mantel is a decorative shelf above the fireplace. Can be made of brick but also of wood, plaster, stone, cast iron or other decorative materials.

(11) Crown also called a Wash, is a sloped bed of mortar that helps shed rain water. When this crown is cracked or deteriorated then rain can be absorbed into the chimney and cause rapid deterioration.

(12) Chimney Cap helps keep rain from entering the flue. An open flue is like a huge bucket that can allow large amounts of rain water to enter.
(14) Thimble, or breech is the passageway for a freestanding stove or furnace to connect to the chimney.

(15) Cleanout door is used to remove creosote and ash from the chimney. It should be tightly sealed to prevent cool air from entering the chimney as this reduces proper drafting efficiency.
