Fire dampers are suitable for installation in any position in vertical and horizontal passages of fire
separating structures.
The gap between the installed damper and structure must be completely filled with approved material.
The distance between the fire damper and structure (wall, ceiling) must be at least 75 mm. If two or more
dampers are to be installed in one fire separating structure, the distance between the adjacent dampers
must be at least 200 mm.
The damper blade (in its closed position) must be inside of the fire separating structure. The fire damper
may also be installed outside the wall structure. The piping and damper part between the wall structure
and damper blade (marked with the BUILT-IN EDGE label on the damper body) must be protected by
fire insulation.
