Chasing out channels for flat ductwork or flexible pipes
NOTICE
With this installation kit you can connect to the extract air and supply air openings using
either flat ductwork or flexible pipe. The installation example shown in this section is a
configuration with two flat ductwork connections. Section 8.3 from page 21 contains
further variants that can also be used for installation in frame constructions.
► Saw two channels for the extract air duct (item 3 in Fig. 45) and supply air duct (item 4
in Fig. 45) in the upper batten (item 1
in Fig. 45) and the ceiling joist (item 2
in Fig. 45).
► Check that the installation kit fits
easily into the space.
►
If necessary, saw channels for the
rest of the flat ductwork as shown in
your plans.
NOTICE
The dimensions of the channels for the
flat ducts are:
— 118 mm wide
— 60 mm deep
The dimensions of the channels for the
flexible pipes are:
— 170 mm wide
— 85 mm deep
NOTICE
► Observe the following recommendations when using flexible pipes to avoid unnec
-
essary pressure losses in the pipes.
—
Always connect two flexible pipes to the flexible pipe connection.
—
As far as possible, use flexible pipes with a diameter of 75 mm.
—
The total length of each flexible pipe should not exceed 10 m.
—
Minimise the number of bends in the flexible pipes.
—
Run the two flexible pipes of a flexible pipe connection in parallel to one another.
The minimum distance between the flexible pipes must not be less than 3x the
pipe diameter.
