How to Set a Barometric Damper

Save

Barometric dampers contribute to stable heat and efficient fuel consumption by stabilizing flue draft -- in other words, regulating the flow of hot air in a chimney so that air flow is neither excessive nor lacking. As draft increases, barometric dampers automatically cause a flap to swing open wider, drawing "room air" into the flue and reducing draft. Thus, they prevent problems of high draft such as erratic burning and wasted fuel. Conversely, as draft reduces, the flap closes to reduce air, allowing the flow of hot air. The proper adjustment of barometric dampers is integral to their functioning.

Things You'll Need

  • Manufacturer's specifications
  • Fire the unit at full rate on a typical cool day.

  • Locate on the barometric damper the draft gauge and weights. The weights should be adjusted according to manufacturer's specifications to obtain a standard draft gauge reading when the burner is operating at normal temperatures.

  • Adjust the damper weights until the draft gauge reads between the specifications supplied by the manufacturer. As draft increases above this level, damper doors will open, helping to keep draft constant.
