What does a barometric damper control?

What does a barometric damper control?

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.

How many wires control a barometric damper?

should use 20 gage or larger wire. Each damper actuator requires 3 conductors. The connection to thermostats and equipment (furnace or fan coil) could require as many as 8 conductors for a multi-stage installation.

Where do you put a barometric damper?

The barometric damper is installed in the flue between the boiler and the chimney. It is set for the desired draft conditions using weights and adjustment screws.

Is a barometric damper needed?

A barometric damper is needed to help assist the chimney with proper function. A barometric damper regulates the chimney draft. Over time pressure can build up in the chimney ducts and the barometric damper job is to regulate and release the built-up pressure.

How do you wire a duct damper?

Open up the duct work, and drill two holes on opposite edges of the tube. These holes should line up with the pre-drilled holes on the damper. Remove the fasteners from the damper, connect it to the duct through these holes and into the drilled holes, and tighten. Then, seal both sides with duct tape.

When would you use a barometric damper?

Do you need a barometric damper on a oil furnace?

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 damper?

A damper was traditionally used on older, less efficient, models of stove to help reduce the flow of air leaving the firebox. Certified modern stoves meet stringent regulations and typically won’t need a damper to perform well.

What should the barometric damper be adjusted for?

“The barometric damper should be adjusted (by adjusting the weight position) to maintain as low a draft as will give good combustion and meet the requirements for heat. The bracket is marked “Lo”, “Med” and “Hi” which correspond to draft settings [if draft is measured inside the flue immediately before the regulator] of 0.2″, 0.4″, and 0.6″ w.c.”

How are barometric dampers used in oil fired heaters?

Barometric dampers are devices used to regulate the draft on oil-fired heating equipment such as furnaces, boilers, or water heaters. 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.

Why do you need a barometric draft control?

Forced Draft installed with a stack height in excess of 30 feet will probably develop excessive natural draft, reducing the amount of pressure within the furnace or boiler. A barometric draft control will help eliminate this undesirable stack action and permit the unit to be pressurized.

How to replace field controls 6 in.damper?

Wear some gloves and twist out the old damper and insert the new one, the new damper has to be leveled tough, if you own a drill you can also drill new holes to secure the new damper or leave for the repairman.
