Before embedding, the fire damper should be placed axially in the partition (wall or ceiling constituting the fire zone division), in an opening prepared beforehand. Then it should be levelled and fixed. For fire dampers of dimensions above 700x700 insert the strutting elements. After these operations, the fire damper baffle (set of blades) should be actuated manually to check if it turns correctly (does not knock against casing elements).Close its blades. Fix the device using masonry mortar (Figure 7.), carefully preventing the mortar, glue and paint from getting onto the operating elements of the fire damper (tripping and control mechanism, baffle, gaskets, limiters). For this purpose, before installation absolutely protect the fire damper with protective film or other covering material until the masonry and finishing work is completed. This baffle must remain closed until the mortar sets. After the concrete mortar sets, remove the brackets and again open and close the fire damper to check if its baffle
