What is a barometric damper on an oil furnace?

Draft regulators or barometric dampers are devices used to regulate the draft on oil-fired furnaces, boilers, and water heaters. You adjust the weight to control the amount of the opening of this damper which in turn controls the amount of excess air that can enter the flue and chimney when the oil burner is operating.Click to see full answer. Herein, what does a barometric damper do?Barometric dampers are a device installed into the flue between the heating appliance and the chimney to control draft. Barometric dampers are used in a wide range of heating appliances including furnaces, boilers, fireplaces, and stoves.One may also ask, how do you install a barometric damper? How to Install a Barometric Damper Step 1 – Check the Installation. Check if the installation of your barometric damper complies with local building code rulings. Step 2 – Check the Chimney. Step 3 – Install the Barometric Damper. Step 4 – Check the Connector. Step 5 – Screw the Pipes. Step 6 – Check the Installation of the Damper. Beside above, does an oil furnace need a damper? Oil burners, which are forced draft (the fan pushes air into the combustion chamber), require a single-acting barometric damper. That’s why we need to allow room air into the vent to balance the pressure, control the draft rate and allow the exhaust to flow up the chimney.Do I need a barometric damper?A barometric damper is a great solution. High draft will cause excessive velocity of the flue gases and this will not allow the heat to transfer into the boiler. The barometric damper will be installed in the flue between the boiler and the chimney.
