A chimney damper is a metal plate that is installed in the throat of the chimney. The damper controls the airflow in the chimney, and it also prevents cold air from coming into the home through the chimney. The damper should be open when the fireplace is in use and closed when the fireplace is not in use. If your chimney damper is not working properly, it can cause a number of problems, including drafts, smoke coming into the home, and even fires.
There are two main types of Chimney dampers – Top-selling dampers & bottom-sealing dampers.
Top-sealing dampers- located at the top of the chimney, just below the cap
They have a rubber gasket that seals the flue when the damper is closed. The damper is opened and closed with a lever or handle that is located inside the fireplace. When the damper is open, it allows smoke and gasses to escape up the chimney.
Bottom-sealing dampers- located at the bottom of the chimney, just above the firebox.
This type of chimney damper works similarly to top-selling dampers, but they are not as effective at sealing the flue. The damper is mounted on a hinge at the bottom of the chimney and is opened and closed with a handle that is attached to the outside of the fireplace. When open, this type of damper allows smoke and gasses to escape up the chimney. To close it, push or pull on the handle until it locks into place.
Both types of dampers are designed to prevent cold air from entering the home through the chimney, but they operate differently
First Identify the type of chimney damper you have.
Once you know which type of damper you have, opening or closing it is simple.
For a top-selling damper, just lift up the handle to open it.
For a bottom-sealing damper, push down on the handle to open it.
To close either type of damper, simply reverse the process.
It’s important to make sure that your chimney damper is both open and closed when necessary.
You should open the damper before lighting a fire. This will allow the smoke to escape and prevent carbon monoxide buildup.
Top-mounted & Regular bottom dampers should be closed when the fire goes out to prevent heat from escaping through the chimney and allow cold air into your home and increase your heating bills
Likewise, if it’s left closed when there is a fire in the fireplace, it can cause dangerous Smoke & Carbon monoxide to build up inside your fireplace.
If you are having problems with your damper, it is best to call a professional for help. A qualified technician can repair or replace your damper and make sure that it is working properly.
