The unit operates more efficiently, reliably, and requires less maintenance. A barometric damper is also very helpful in times of fire and opens up which allows the fire to. As time goes by, the pressure gets built up in the ducts of your chimney, and the barometric damper releases that pressure. As we’ve discussed above, it regulates the chimney draft. The velocity of combustion gases through the heat exchanger is slowed so more heat is extracted. A barometric damper is one of the mechanisms inside your chimney. Combustion of fuel is complete and the process is stabilized. 3 - Barometric Draft Control Model B-34 In all barometric damper (draft regulator) installations, the face of the draft control must be plumb and the hinge or bearing surfaces must be level regardless of whether the draft control itself is mounted on a vertical, horizontal, or sloping flue vent connector pipe. The device may be installed in a horizontal, angled or vertical run of. A barometric draft regulator maintains consistent draft by counteracting the negative forces caused by changes in temperature. This device may be installed depending on the stove arrangement with the curved end up or down. Decide on the orientation of the barometric damper.

Room temperature air enters through the barometric draft control in the precise amount needed to overcome the excess drafts caused by temperature variations, wind fluctuations, and barometric pressure changes. Using a screwdriver, secure stove pipes and/or elbow joints with at least three sheet metal screws. The pressure difference between the room air and heated gas (air) causes products of combustion to flow (draft) through the unit and rise through the breach and chimney. Pressure in a boilers stack can greatly affect the combustion process potentially costing you m.
6 BAROMETRIC DRAFT CONTROL DAMPER HOW TO
How do draft controls work? S tatic pressure of the cool air exerts pressure on the outside of the furnace or boiler, the breaching, and stack. Learn how to manage the pressure in a boilers exhaust stack. Proper draft for most coal and wood burning stoves will be measured with a draft gauge reading of between 0.04 to. The M employs side wings to control air direction with gate curvatures designed to compensate for differences in horizontal and vertical settings. The Type M features an infinitely variable screw adjustment, permitting an extremely fine instrument setting. 1″, the Field Controls Type M draft control is recommended for oil or coal-fired residential heating applications. FIELD CONTROLS Barometric Draft Control: 6 in to 8 in, Galvanized Steel, 38.5 Nominal Capacity Image of 45DX70 Image of. The M control lends itself ideally to conditions requiring a great deal of stability and accuracy.
