The fireplace shutter completes the flue of the fireplace, distributing warm air through gravity or mechanical means. It is installed on the wall of the chimney. The construction of the Luft shutter is characterized by a hidden air duct. During installation, it is important to ensure proper orientation. The air intake of the shutter should be at the bottom, while the outlet should be at the top. This will ensure adequate circulation of warm air. The shutters are powder-coated, which offers color and heat resistance. Additionally, the coating protects the shutter from mechanical damage.
