9.2 Installing the wall duct
Caution.
b
Risk of damage to the air pipe and unit.
The air pipe and the unit may become dam-
aged if moisture (e.g. rainwater) enters the
system.
> Always install the outer part of the wall
duct (2) on a horizontal plane.
> Ensure that the air intake slots (3) are
always pointing downwards.
Caution.
b
Malfunctions.
If you pull out the wall duct from the out-
side, this can lead to malfunctions of the
unit.
> Seal the drilled hole from inside and out-
side with mortar (1).
> Leave the mortar to harden.
> Slide the wall duct (2) through the drilled hole in the wall
until the wall duct projects outwards out of the wall by
160 mm.
> Install the stainless steel cover plate (3, ¬ Fig. 9.1).
> Install the white cover plate on the inside (2, ¬ Fig. 9.1).
> If applicable, install additional extensions and elbows
starting from the wall and working towards the unit.
> Attach one fastening clamp for each extension.
> Finally, insert the elbow of the flue gas pipe into the flue
gas connection of the unit.
> Connect all connecting points of the air pipes using a
safety screw as described in ¬ section 10.

Important information for the pipe guiding
> Determine the pipe guiding so that the following condi-
tions can be complied with:
1. The horizontal flue pipe must be at a 3° downward
gradient to the unit (5 cm + 1 cm tolerance per metre
of pipe length).
Danger!
a
Risk of poisoning due to escaping flue
gas!
Standing condensate can damage the seals
of the flue gas pipe.
> Lay the horizontal flue pipe with a down-
ward gradient of 3° inwards.
3° corresponds to a downward gradient
of approx. 50 mm per metre of pipe
length.
2. The pipes between the unit and the vertical part of
the flue gas pipe must be pushed into each other until
they reach a stop.
3. It must be possible to secure each pipe to the ceiling
or the wall.
Danger!
a
Risk of poisoning due to escaping flue
gas!
Extensions that are not secured to the wall
or ceiling may bend and separate due to
thermal expansion. Flue gases may escape.
> Secure each extension to the wall or ceil-
ing using a pipe clamp.
> To do this, use the pipe clamps that are
each secured into the wall or the ceiling
using a hanger bolt or threaded bolt
M8/M10. This allows for sufficient elastic-
ity of the fastening in the event of ther-
mal expansion of the pipes.
> The distance between two pipe clamps
must not exceed the length of the exten-
sion.
