What does a barometric damper control?
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. The barometric damper plays an important role in fire safety.
Is a barometric damper a draft control device?
Draft regulators or barometric dampers are devices used to regulate the draft on oil-fired furnaces, boilers, and water heaters. In this way you adjust the draft over the fire in the appliance.
When would you use a barometric damper?
A barometric damper is a great solution. High draft will pull the flue gases too quickly through a boiler, not allowing the heat to be transferred into the boiler. The barometric damper is installed in the flue between the boiler and the chimney.
Does a wood furnace need a barometric damper?
A barometric damper should never be installed on a wood stove. It will allow cool air into the flue, both slowing flue gases and increasing the likelihood of the smoke condensing and forming creosote. A barometric damper will also cause very rapid feeding of a chimney fire if one were to start.
Where should a barometric damper be placed?
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.
Where do you put a barometric damper?
Where should the barometric damper be installed in the chimney connector?
On oil fired equipment the barometric damper, or draft regulator is typically a round Tee inserted in the flue vent connector between the heating appliance and the chimney.
How does a barometric damper work on a wood furnace?
An adjustable weight system is how the barometric damper functions. The weight is adjusted so that the door in the barometric damper system swings open or closed depending on how much air the fire needs. The more air that’s let in, the more the fire will burn.
What is the function of a draft hood?
A draft hood is placed above the upper most part of the gas furnace to draw air into the chimney and makes it possible to draw more or less air through the chimney as necessary to create a constant flow.
