1 Aluminium sealing tape
f Seal the transition from the air connection to the air duct
with aluminium sealing tape.
10.4.3 External wall outlets
Install the outdoor air intake into the building at a location where
contamination (dust, soot, odours, flue gas, microorganisms, ash,
exhaust air) is as low as possible.
When installing external wall outlets, prevent any short circuit
between the air intake and the air discharge.
10.4.4 Silencers
f Install a silencer in both the supply air duct and the extract
air duct. Install these silencers as close as possible to the ap-
pliance, so that noise is suppressed at an early stage.
We recommend installing additional silencers if required to avoid
sound transmission.
If a room with a high noise level needs to be ventilated, install
additional silencers upstream of this room to reduce sound trans-
mission to the neighbouring rooms.
Aspects such as carried voices and impact sound must also be
taken into consideration in the case of ducts embedded in con-
crete. Carried voices should be avoided by designing the duct with
separate branches to the vents. If necessary, insulate the supply air
ducts, e.g. if they are mounted outside the insulated wall panel.
10.4.5 Overflow apertures
Living rooms and bedrooms are only supplied with air. Air is only
extracted from rooms where odours and moisture are generated.
Ensure an unimpeded overflow and consequently air balancing.
Install ventilation grilles in internal doors or walls, or enlarge the
air gap beneath the door to ≥ 8 mm.
10.4.6 Cleaning apertures
f Fit cleaning apertures when installing the air ducts, so
that the air ducts can be inspected and cleaned at regular
intervals.
10.4.7 Supply and extract air vents
Supply and extract air vents for the living space are available for
wall or ceiling mounting.
When venting the kitchen, ensure that the extract air vent is fitted
as far as possible from the cooker.
