The oil furnace system consists of a burner, which, as its name suggests, burns the fuel oil in the furnace's combustion chamber. The flue gases then pass through the air generator where heat is released into a heat exchanger. The gases produced are then vented to the outside via the flue pipe and the chimney. Thereafter, a fan circulates the air coming from the return of cold air from the house into the heat exchanger. The heated air is finally distributed through the house's hot air ducts.
