Where is the smoke shelf located in relation to the damper?

The smoke shelf is located behind the damper in a chimney system. It serves an important function in directing smoke and gases up the flue while also providing a place for any condensation from the combustion process to collect. When the damper is closed, the smoke shelf helps prevent cold air from entering the chimney and causing drafts into the living space. This placement ensures that the smoke shelf can effectively capture and redirect smoke properly whenever the damper is opened during a fire. Understanding the positioning of the smoke shelf in relation to the damper is essential for recognizing how chimney systems are designed to work efficiently and safely.
