How does a damper function in a fireplace?

A damper in a fireplace primarily functions to control the draft. This is crucial because the draft determines how much air flows into the fireplace and how smoke exits through the chimney. When the damper is opened, it allows air to enter the firebox, which enhances combustion and helps to ensure that smoke is effectively drawn up the chimney. Conversely, when the damper is closed, it restricts this airflow, which can help to prevent cold air from entering the home when the fireplace is not in use.

The ability to adjust the damper enables a fireplace user to optimize burning efficiency, reduce smoke production, and enhance overall safety by directing smoke outside. Understanding how to properly utilize the damper contributes to a safer and more efficient fireplace experience.
