3 Operating Conditions
Fire dampers can be defined as fire shutters for ventilation ducts in the place where they pass through walls or ceilings,
which are the borders of the fire area. In case of fire, the dampers function as a fire safety element and by closing, they
prevent the fire and smoke from expanding through the ventilation duct during the defined time. The fire dampers are
intended:
• For installation in places which are protected against weather disruptions.
• For ducts, distributing air without any mechanical or chemical contamination.
• For maximum air flow velocity 10 m/s.
| A001

4| Installation
4 Installation
• The duct connected to the fire damper must be supported or hung in such a way that the damper does not carry its
weight. The damper must not support any part of the surrounding construction or wall which could cause damage
and consequent damper failure.
• Easy access to mechanism and internal parts during inspection must be considered during damper placement.
• According to the standard EN 1366-2, the distance between the fire damper bodies must be at least 200 mm.
• The distance between fire damper and the adjacent wall/ceiling and the fire damper must be at least 75 mm.
• When the F-B90 fire damper is installed into a smoke and fire partition structure, it must be placed so that the damp-
er blades in its closed position are located inside this structure.
• The gap in the installation opening between the fire damper and the wall/ceiling can be increased by up to 50% of
the gap area or decreased to the smallest amount possible that still provides sufficient space for the installation of
the seal.
• When using non-original grilles, the gap between the damper blade in open position and the self-standing grill,
mesh, louvre must be at least 200 mm according to EN 1366-10.
• The fire damper must be earthed after being installed into or onto the duct.
• Lists of all permitted installation methods are provided in User Manual.
4.1 Installation Methods
Fire dampers are certified according to EN 15650:2010, tested according to EN 1366-2:2018 and classified according
to EN 13501:2018.

4.3 Installation Distances
The minimum distance from the wall or ceiling to the damper body is 75 mm. For multiple crossings through a fire resis-
tive wall, the minimum distance between two damper bodies is 200 mm. This applies for distances between the damp-
er body and a nearby foreign object crossing the fire resistive wall. Damper clearances vary from the type of
mechanism and their rotation.

4.4 Handling and manipulation of F-B90
Handling and manipulation of the F-B90 must be done with care. All dimensions of fire damper should be manipulated
and placed in the installation opening by two persons. For added safety and easier handling recommend using the suit-
able lifting equipment (forklift, crane) for bigger dimensions of fire damper. Please follow both textual and graphic
instructions:
1. Unpack the fire damper( 1)
2. Remove grilles (4)
1. Prepare the opening, connection surfaces and/or filling
as per the desired installation type
2. Carefully lift the fire damper with forklift, crane
3. Place the fire damper in vertical position
4. Place the fire damper in the opening as a desired
installation type (A1,A2)
•A1:For Soft Crossing or Fit installation place the fire
damper on filling (3)
•A2:For Wet installation place the fire damper on
support (9)

remove them (B1)
2. Pull the strap/tap and remove the mechanism cover
(B2)
3. Use top or bottom transitions and pull the actuator
cables through them (B3)
4. Safely connect the actuator cables to wiring
5. Fix the mechanism cover with screws

4.5 Wet Installation
Wall Installation Using Plaster/Mortar/Concrete Filling
1. The supporting construction opening must be prepared in a way depicted in the “Opening Preparation for F-B90 In-
stallation” section. Opening surfaces must be even and cleaned off. The flexible wall opening must be reinforced as
per the standards for plasterboard walls. The opening dimensions are driven by the nominal dimensions of the damp-
er with added clearance. The opening will be with the dimensions of W1and H1.
2. Insert the damper as per the “Handling and manipulation of the F-B90” section into the middle of the opening so that
the damper blade is in the wall. For damper widths greater than 600 mm, it is recommended to use a duct support in-
side the damper during installation to avoid any damage caused to the damper housing by the weight of the filling.
3. Fill in the area between the wall and the damper with gypsum plaster or mortar or concrete filling (3) while paying
attention to prevent the fouling of the damper’s functional parts, which could limit its correct functionality. The best
way is to cover the functional parts during installation. To prevent seepage of the filling material, use of boards is
recommended.
First, let the plaster or mortar or concrete filling harden and then perform the next steps.
4. After the filling hardens, remove the duct support from inside of the damper.
5. If needed, uncover and clean the damper after installation.
6. Check the damper’s functionality.
