Barometric Draft Controls

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.

This Field unit works to perfection. Others seem to “hang up” at low draft settings, making them essentially inoperative. It stabilizes the draft to any appliance located below the barometric draft control. A counterbalanced flap opens and shuts depending on the strength of the negative pressure (draft) in the chimney. As the flap opens (with greater draft), more air is let into the chimney, thereby decreasing the draft to the appliance.

Field Barometric Draft Controls have adjustable weights which allow the units to be set for the particular draft required. 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. The draft control can only decrease draft, it has no ability to increase draft.

In cases of excessively strong draft, two barometric controls in series may be required.

Constant Heat, Longer Burn
The automatic stabilizing effect on the fire will generally lengthen the duration of burn and maintain a more constant heat output. Research has also linked the use of barometric dampers with substantial creosote reduction in the operation of woodstoves. (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.)
Both coal and wood stoves will benefit from the installation of a barometric draft control.

Caution: Some tees have too short or too long a neck. A barometric draft control will not function properly with these tees. Minimum dimensions of the neck of the tee to the closest point on the perpendicular flue pipe section are:

Pipe Diameter Neck

6"

2 11/16"

7"

4 3/8"

8"

4 3/8"

When used with woodstoves, the connector pipe and flue must be inspected and kept clean. A barometric draft control can potentially lengthen and intensify any chimney fire by allowing an unlimited supply of combustion air.
