The barometric damper or draft regulating device we are discussing here is normally used only on oil-fired heating equipment, not on gas-fired equipment. ![]() A barometric draft control can potentially lengthen and intensify any chimney fire by allowing an unlimited supply of combustion air.Google has not performed a legal analysis and makes no representation as to the accuracy of the date listed. Barometric dampers are devices used to regulate the draft on oil-fired heating equipment such as furnaces, boilers, or water heaters. Note: When used with woodstoves, the connector pipe and flue must be inspected and kept clean. Field Draft Controls maintain consistent draft by counteracting the negative forces caused by changes in temperature. ![]() tee with black finish barometric draft control.

(These findings must be kept in perspective, as woodstoves operated at extremely slow burn rates can still produce dangerous levels of creosote, even when operated with a barometric damper.)īoth coal and wood stoves will benefit from the installation of a barometric draft control.īlack 24g. Research has also linked the use of barometric dampers with substantial creosote reduction in the operation of woodstoves. The automatic stabilizing effect on the fire will generally lengthen the duration of burn and maintain a more constant heat output.

In cases of excessively strong draft, two barometric controls in series may be required. The draft control can only decrease draft, it has no ability to increase draft. They will do an excellent job of maintaining the draft setting within reasonably close tolerances except when the total draft in the chimney drops below the setting on the barometric draft control. As the flap opens (with greater draft), more air is let into the chimney, thereby decreasing the draft to the appliance.įield Barometric Draft Controls have adjustable weights which allow the units to be set for the particular draft required. A counterbalanced flap opens and shuts depending on the strength of the negative pressure (draft) in the chimney. It stabilizes the draft to any appliance located below the barometric draft control. Others seem to “hang up” at low draft settings, making them essentially inoperative. We’ve Examined A Lot Of Draft Controls, Some Cost More And Some Less, But The Field Barometric Draft Control Is The Best We’ve Found For Both Operation And Price.
