This description completes the fireplace channel that distributes warm air either by gravity or mechanically. It is installed on the chimney wall. The design of the Luft shutters is characterized by the presence of a covered air inlet. When installing the shutters, care should be taken to ensure the correct orientation. If you install the fireplace shutters, the air inlets should be at the bottom, while the supply inlet should be at the top. This will maintain adequate circulation of warm air. The shutters are powder-coated, which is characterized by color durability and thermal resistance. Additionally, the coating protects the shutters from mechanical damage.
