Flue

The definition of a flue is a passage for smoke and other gases created by a fire or furnace. It is typically a metal or brick tube that is connected to the chimney and is used to direct the flow of hot gases from the fire to the outside. The flue is an important part of the chimney system, as it is responsible for controlling the draft and ensuring that the smoke and gases are safely vented away from the building. The flue also helps to keep the temperature of the chimney and the surrounding area consistent, which helps to prevent the spread of smoke and fire. The flue is typically lined with a material such as clay, cement, or metal to protect it from the heat of the fire. Proper maintenance of the flue is essential to ensure that it is working properly and that the smoke and gases are safely vented away from the building. Regular inspections and cleaning of the flue should be done to ensure that it is free of debris and that the draft is working properly.
