4. Placement and Assembly
4.1. Fire dampers are suitable for installation in arbitrary position in vertical and horizontal passages
of fire separating constructions. Damper assembly procedures must be done so as all load
transfer from the fire separating constructions to the damper body is absolutely excluded.
Back-to-back air-conditioning piping must be hung or supported so as all load transfer from the
back-to-back piping to the damper is absolutely excluded.
3.3. For fire damper the open damper blade overlaps the damper body from dimension 250 by the
“a” value. These values are specified in the Tab. 3.2.1
Value has to be respected when projecting related air-conditioning piping.
