5. HANDLING AND STORAGE

Since this is safety equipment, the fire damper needs to be stored, handled and installed with care.

Attention:
• Avoid contact with water and exposure to excessive dampness.
• Avoid damage to sealing/gasket during installation. Be careful especially to the external sealing/gasket.
• Avoid deforming the duct during assembly and sealing.

It is best to:
• Unload in a dry area.
• Avoid impacts.
• Do not use the damper as a work table or scaffolding.
• Do not put small dampers into bigger ones.
6. INSTALLATION AND COMMISSIONING
• Installation is possible with the blade axis in horizontal or vertical position.
• The installation must comply with the CE Certificate.
• Never obstruct the blade movement with any object or air ducts.
• The air tightness and fire resistance class is maintained if the damper installation is done in compliance with the
technical specifications.
• Use temperature: 50°C maximum.
The WK25 fire damper is always tested in the frame of standardised supports in compliance with EN 1366-2 : 1999
table 3/4/5'. The results obtained are valid for all similar support frames which have a thickness, density and fire
resistance equal or higher than that of the test.
Example of similar constructions:

aerated concrete wall thickness 100 mm +
density 550 kg/m3 + fire resistance up to 120
minutes 
brick walls, reinforced concrete, aerated
concrete wall, etc.+ fire resistance minimum 120
minutes 
aerated concrete floor thickness 100 mm +
density 650 kg/m3 + fire resistance up to 90
minutes 
parts in concrete, prestressed concrete, etc.
+ fire resistance minimum 90 minutes 
flexible wall – metallic uprights +
plasterboard: 100 mm + fire resistance 60

Damper installation:
1. A rectangular hole sized (B + 75 mm) x (H + 75 mm) must be provided in the wall with a frame made by metal profiles
ideal for use with plasterboard (min. thickness 0,6 mm).
2. Cover the internal perimeter of the opening with a 12.5mm thick layer of plasterboard and a width equal to that of the
wall.
3. Place the damper in the hole.  he damper protrudes from the wall by 185mm.
4. Fill the gap between the damper and the wall using rock wool 80 kg/m³.
5. Apply plasterboard strips (thickness 12,5 mm) on both sides to cover the rock wool.

2. Position the damper in the hole on the wall.
3. It is not necessary to insert any material, simply cover the gap between wall and fire damper applying on both faces of
the wall a layer of plasterboard, to a minimum thickness of 12,5 mm per side.
4. Set up a mechanism clearance and access area: 250mm
