Barometric dampers are devices used to regulate the draft on oil-fired heating equipment such as furnaces, boilers, or water heaters. Subtract the smaller from the larger to get correct static pressure drop in inches of water. For adjustment of barometric draft controls, follow furnace or boiler manufacturer's recommendations for over-fire draft setting.ĪIR FILTER TEST-To obtain pressure drop across an air filter, follow pro- cedure outlined above to determine static pressure on each side of the filter. To determine draft loss through furnace, subtract over-fire draft reading from smoke pipe draft. For last pass or smoke pipe draft, connect into the breeching on the furnace side of any damper or draft control. Dynamically regulate the air outside of your boiler and within. Holding meter vertically, insert angle connector into furnace combustion chamber for over-fire draft reading. Control drafts and regulate the flow of flue gasses through boilers with barometric dampers.

Secure supply grille probe to angle connector, place over opening permitting as little leakage as possible and read static pressure as above.įURNACE DRAFT-Secure angle connector to center connection of Air Meter with rubber tubing.

For accurate static pressure measurements in ducts and equipment having appreciable air velocity, select a location where duct face parallels air stream and drill a 1/4˝ opening, leaving minimum burr.

Yet, its too warm to have a coal fire going in the shop. My chimney always has draft, especially on a windy day. Or, to make sure the chimney IS drafting higher than adjustment target. Hold meter vertically, inserting angle connector in unit under test, and read pres- sure in inches of water on appropriate high or low range scale. Any time Ive read about adjusting the barometric damper, its been mentioned that the fire be up to speed.

For plus pressure readings, use outer connector. For minus pressure readings, use center con- nector on the meter. STATIC PRESSURE-To read static pressure, secure angle connector to meter with tubing supplied. To read on low range scale, do not cap con- nector. To read on high range scale, cap exposed connector with finger as shown in sketch. Height of ball indicates static pressure or air velocity.Īir velocity is registered from 260 to 1200 fpm on low range, 1000 to 4000 fpm on high range. With the meter in a vertical position, air comes in through the outer of the two top connectors, passes into the scale chamber and enters the tapered indicating tube at the bottom, causing the white plastic ball to lift.
