This fireplace shutter completes the distribution of warm air intended for the fireplace, either by gravity or mechanically. It is installed on the wall of the chimney, and the construction of the shutter is characterized by the presence of a hidden air duct. During the installation of the shutter, care must be taken to ensure the correct orientation. The shutter should be placed with the air intakes at the bottom and the inlet connection at the top, so that adequate circulation of warm air is maintained. The shutters are powder coated, which is characterized by color and temperature resistance. Additionally, the coating of the shutter protects against mechanical damage.
