Air distribution
Air is distributed through air distribu-
tion boxes with flat ducts (system 100)
in conjunction with suitable branches,
silencers, clean-out covers and air
outlets/inlets.
Routing the air supply ductwork takes
priority over the heating, DHW and
drainage networks to avoid compli-
cated pipe runs.

Routing lines
&Secure the air distribution system
with clips or perforated straps.
&Never let lines sag to prevent the
accumulation of condensate.
&Push individual elements together
with joints or female connections.
&Secure joints with self-tapping
screws or blind rivets and seal air-
tight with shrink tape.
&Use reducers in accordance with
the required flow rate and the pre-
vailing building conditions.

&Never let drilling swarf drop into the
device connectors.
&Secure the flexible pipe with a hose
clip to the ventilation air connector
on the device.
Thermal insulation
Thermally insulate parts of the air dis-
tribution system that are routed
through unheated areas.
Provide outside air and expelled air
lines with a vapour diffusion-proof
insulation layer.
Provide ventilation air and extract
air lines with an insulation layer of at
least 50 mm thickness.
Preventing flow noise and pressure drop
&Install the air distribution box near
the central device.
&Maintain a max. distance between
the ventilation air and extract air
lines from the device and the air dis-
tribution box of 5 m.
&Install silencers on the ventilation
air and extract air side immediately
above the device (behind the adap-
tor from round to flat).
&Symmetrical ductwork design.
&Short runs, few bends.
