A vertical channel or conduit, typically made of brick, stone, or metal, serves to expel smoke and combustion gases from a fireplace, furnace, or stove. This structure is an integral component of residential buildings, facilitating the safe and efficient removal of byproducts generated by heating or cooking appliances. Its location is generally on the roof of the house.
Such structures are critical for maintaining indoor air quality and preventing the buildup of hazardous substances like carbon monoxide. Throughout history, these elements have been essential for heating homes, providing a means to vent smoke away from living spaces and contribute to safer and more comfortable environments. Their design and construction have evolved over time, reflecting advancements in building materials and heating technologies.
