Damper

A flow control at the throat. It was never designed to seal and does not.

What is Damper?

A plate that opens and closes the throat above the firebox. Its function is regulating a working fire, not sealing an idle flue — a distinction that matters because heat loss through an open chimney is a real and continuous cost that a throat damper does not address. A top-sealing damper at the outlet is the component that does.
