Fireplace Dampers & Chimney Dampers
Smoke back drafting into the home

Have you ever watched someone fumbling with a damper on a smoky fire? A fireplace damper acts as a gateway for the chimney, opening to let air pass through or remaining shut to keep the chimney sealed. They're a simple mechanism, but how do you know when they should be open or closed? And should they ever be left partially open?

Here's a guide to the different kinds of chimney dampers and how to operate the different styles. You'll also find tips on how to replace or install them.

What is a Fireplace Damper?

A fireplace damper is a simple flap that opens and closes inside the flue of your fireplace. When closed, it seals off the chimney so that warm air from your house doesn't escape. (No one enjoys paying to heat the outdoors.) When open, it allows the fire to vent properly and let the smoke go up the chimney.
