Ventilation systems require a conduit to safely expel exhaust gases from appliances like furnaces, water heaters, and wood-burning stoves. These components, typically cylindrical in shape, are available at major home improvement retailers. They are crucial for directing combustion byproducts away from living spaces, preventing the accumulation of dangerous substances such as carbon monoxide.
Proper ventilation is paramount for both safety and appliance efficiency. A correctly installed and maintained system prevents backdrafting, ensures complete combustion, and maximizes the lifespan of the connected appliance. Historically, the materials used for these systems have evolved, moving from masonry to more durable and corrosion-resistant metals, reflecting advancements in building codes and safety standards.
