Page: 28 / 164

Insulation is non-hazardous in terms of fire safety if the
following requirements are met:

the insulation does not impair the function of the fire
damper,

The fire damper remains accessible.

The inspection accesses and product sticker remain
accessible.

The insulation does not penetrate walls or ceilings.

2.1 Mortar
3.1 Solid wall
6.16 Insulation (elastomeric foam, flame-resistant, non-
dripping), around the perimeter, actuator and
release mechanism, inspection accesses and
product sticker must be accessible
9.2 Extension piece or duct
Up to EI 120 S
Note: The installation situation shown is representative
of all supporting constructions.
The following applies to Germany:
In Germany, only insulation materials with a fire behav-
iour of at least C - s2, d0, may be used according to the
specifications of the MVV TB (since 2019/1). This
requirement is met by Armaflex Ultima insulation mate-
rial from Armacell, for example. The applicable local
building regulations must be observed.
For notes on the use of elastomeric foams, see

Extension pieces
To ensure that the fire damper can be connected to the
ductwork after installation even if the wall or ceiling is
fairly thick, you should extend the fire damper with a
suitable extension piece (attachment or extension by
others) on the installation side

Installation positions
The fire damper may be installed so that the damper
blade shaft is horizontal or vertical or in all intermediate
positions (0 – 360°).
Fig. 12: Installation positions and distances
a Distance between two fire dampers; see

The distance also depends on the installation situa-
tion and is given in the installation details.
If a duct smoke detector is installed in the connected
duct, it must be positioned at the top, regardless of the
installation position.
Deviating arrangements are possible, provided that the
specifications of the general building inspectorate
licence of the duct smoke detector are observed.
