This image is a detailed cross-section diagram of a traditional brick fireplace and chimney, with labels for each component.

Fireplace and Venting Components

* Hearth Extension: The part of the fireplace that extends into the room, typically made of non-combustible material like brick or stone to protect the flooring from embers.
* Fire Box: The inner chamber of the fireplace where the fire is built.
* Face Brick: The visible brick on the front of the fireplace.
* Lintel: A horizontal, non-combustible beam, usually made of steel, that supports the weight of the masonry above the opening of the fire box.
* Smoke Chamber: The sloped area directly above the fire box, designed to funnel smoke and gases into the chimney flue.
* Smoke Shelf: A flat shelf at the bottom of the smoke chamber, which is essential for preventing downdrafts and returning cold air that may enter the chimney.
* Damper: A movable plate, typically made of metal, that can be opened or closed to control the draft and prevent heat from escaping the house when the fireplace is not in use.

Chimney Components
* Flue Tile: The inner liner of the chimney, made of clay or another material, which contains the smoke and gases. Its smooth surface helps with the updraft and protects the surrounding brick from corrosive byproducts.
* Mortar Joint: The cement-based material that bonds the bricks together.
* Chimney Crown: The sloped concrete or masonry cap at the top of the chimney, designed to shed water and protect the brick from rain.
* Chimney Cap: A cover installed at the very top of the flue to keep out rain, debris, and animals. It often includes a mesh to prevent birds or other animals from nesting inside.

This diagram provides a clear anatomical view of how a fireplace and chimney work as a complete system, from the firebox up to the chimney cap.
