Barometric dampers stabilize flue draft by drawing "room air" into the flue.
Why do this?
Too much draft causes erratic burning and wasted fuel. A stable draft provides stable heat and efficient fuel consumption.
It operates automatically. A flap swings open wider as draft increases, thereby letting in more air. And as draft reduces, the flap closes to reduce air. This model is high-quality and packed individually, each with its own tee included. The 5" and 6" dampers are 24-gauge; and the 8" damper is 20-gauge.
Even on airtight stoves, many people desire "old fashioned" cast-iron stove pipe dampers which are located in the flue pipe. These have one piece spring handles for convenient adjusting.
