ON & OUT of the wall installation, EI60S
Using 1 layer of Mineral Wool
TIP: The duct-wall cavity filling can be also replaced by plaster/mortar/concrete (F2) as a replacement of filling (F9),
then the coating (F10) is not needed for the cavity filling.
There are two hanging possibilities, using ringlet MP-MX or using ringlet UVH30 see instructions point 3. Prepare the
damper for installation by fastening in the blade and perforation location with ceramic adhesive tape (12) and bind it
up using a suitable sheet metal ringlet (13 or 14)
1. The supporting construction opening must be prepared as depicted. 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 damper with added clearance. For circular dampers prepare the opening of
diameter D1.
2. Insert the duct into the load-bearing structure along with the damper in such a way that the duct will stick out of
the wall to the needed distance. Press the insulation around the duct (F9) and cut its edges to even it with the wall
surface. Paint the insulation surface in alignment with the wall with a suitable coat of paint (F10) up to 100 mm from
the duct to cover the insulation and part of the wall. Or use as filling plaster/mortar/concrete (F2).
3. Reinforce the circular duct from both sides of the wall crossing with ringlets MP-MX (13) or ringlets UVH30 (14).
4. Depending on the used ringlet embedded in the blade location hang the damper onto:
• threaded rod M12 (11) when using ringlet MP-MX, Hilti (13).
• 2 × threaded rod M10 (15) when using ringlet UVH30, Lindab (14) with nuts (16).
5. Insulate the damper and duct parts between the damper and the wall. Entwine the circular damper and duct with
one layer of insulation (17). Glue the insulation onto the wall using a suitable fire-resistive coating (F10). Secure the
insulation (17) with a binding wire (ř 1,6 mm) in the standard way that is applied when insulating circular ducts or by
using wire clamps (26) to sew together the meshes on the top of the insulation (17). The actuator, thermosensor,
and inspection lid must remain uninsulated with a gap of a max. of 15 mm.
6. Around the front side and on all surfaces that are not covered with aluminum foil, apply aluminum tape (25).
7. If needed, uncover and clean the damper after installation.
8. Make sure the fixing screws are not interfering with the blade movement and check the damper’s functionality.
Installation Distances
For installation 5.2 ON & OUT, the minimum distance from the wall or ceiling to the damper body is 100 mm. For
multiple crossings through a fire-resistive wall the minimum distance between two damper bodies is 200 mm. A
distance 200 mm also applies for distances between the damper and a nearby foreign object crossing the fire-resistive
wall.
Installation in a Wall thinner than tested
Installation in a thinner wall is allowed under the condition that an additional layer/layers of fire protective board are
fixed to the surface of the wall in order to achieve the same length of damper penetration seal as was tested. The
minimum width of added boards around the damper is 200 mm. In addition, the alternative thinner wall should be
classified in accordance with EN 13501-2:2007 + A1: 2009 for fire-resistance required for product application. For a
protruding wall, the additional layers must be fixed on the steel supporting construction of the wall.
