A common problem with barometric dampers is lack of air draft.

Barometric dampers are designed to regulate the flow of air and maintain draft for combustion appliances by balancing pressures in the flue and combustion chamber. A common issue that can occur with barometric dampers is indeed a lack of air draft, which can prevent proper venting of combustion gases.

This can happen due to various factors such as incorrect installation, improper sizing, blockage in the venting system, or even changes in atmospheric conditions that affect draft. If the dampers do not open correctly or are unable to respond to changes in pressure, this can result in insufficient draft, leading to poor appliance performance or unsafe conditions. Thus, recognizing that a lack of air draft is a typical problem associated with barometric dampers supports the truth of the statement.
