(set of blades) is turning correctly. In order to ensure the fire resistance of the fire separation element, unconditionally observe the embedding limit – the axis of rotation of the fire damper blades must not be located outside the wall. In partitions of thickness comparable to the fire damper thickness, the fire damper is embedded so that the fire damper axis is located centrally in its midpoint. Connection of the embedded fire damper to the ventilation duct must be executed coaxially. During installation of the fire damper in the partition, a damage of the fire damper body, and in particular any stresses in the body, must not be allowed. The fire damper must not constitute a „supporting element” of the ventilation system or duct on which it is installed. It is not allowed to drill through the fire damper casing, drive in bolts, screws, or other elements passing through the casing to the inside of the fire damper. After connecting the ventilation duct, check again if the fire damper operation is correct.
