Flue box De Dietrich 0325318

The flue box is a component that collects and channels flue gases from the boiler to the chimney or vent. It is an essential part of the exhaust system, helping to maintain proper draft and prevent backflow. Over time, flue boxes can suffer from corrosion or thermal stress, requiring replacement. Selecting the correct flue box for your boiler model is important for safe and efficient operation.
