Parts of the Chimney You Should Know

February 12, 2024

Understanding the various parts of your chimney can help in its maintenance, troubleshooting, and communicating effectively with professionals during inspections or repairs. Here are 20 essential parts of a chimney you should be familiar with:

Chimney Cap – Sits at the top of the chimney to prevent rain, debris, and animals from entering.
Chimney Crown – Concrete or metal top that seals the area around the flue liner to the chimney edge.
Flue – The inner passageway for smoke and exhaust gases to exit the home.
Flue Liner – A protective lining that enhances safety and efficiency by containing combustion products.
Damper – A valve, usually near the base of the chimney, that opens to allow smoke out or closes to keep the outside air from coming in.
Smoke Chamber – Tapers from the fireplace to the flue, aiding the smooth transition of smoke and gases.
Smoke Shelf – Catches debris and helps prevent downdrafts.
Firebox – The chamber where the fire burns, constructed with fireproof materials.
Ash Dump – A compartment below the firebox that collects ashes for easy removal.
Clean-Out Door – Allows access to the ash dump for cleaning.
Chimney Flashing – Seals the gap between the chimney and the roof to prevent water leakage.
Chimney Chase – A structure that encloses and protects the flue in factory-built chimneys.
Chimney Chase Cover – Covers the top of the chimney chase, similar to a chimney cap.
Throat Damper – Located above the firebox, this damper controls airflow.
Top-Sealing Damper – A damper at the top of the chimney, providing a tighter seal than throat dampers.
Lintel – A horizontal support across the top of the fireplace opening.
Hearth – The floor of the fireplace, extending into the living area.
Hearth Extension – The non-combustible material in front of and at the sides of the fireplace opening.
Mantel – A decorative shelf above the fireplace.
Ash Pit – A pit where ashes from the ash dump are collected.

Each of these components plays a critical role in the safe and efficient operation of your chimney. Regular inspections and maintenance can ensure that they function properly and extend the life of your chimney.
