Installing the fresh air supply and flue
system
The fresh air supply and the flue pipework must correspond
to installation type B. The product features a flue connection
and a 75 mm diameter fresh air spigot as standard. You can
use a parallel two-pipe system for the air/flue pipe. Selecting
the perfect system depends on the specific installation and
application conditions. The maximum length of the flue pipe-
work (for a 75 mm diameter) is 20 m with a maximum of six
90° elbows.
▶
Only use flue systems from Technaflon.
▶
Install the air/flue pipe in accordance with TRGI regula-
tions.
▶
Agree on the air/flue pipe with the chimney sweep.
▶
Observe the installation instructions for flue gas systems.
▶
Lay the flue pipework within the building in an L90 shaft.
▶
Lay the flue pipework within the building such that the
entire length is ventilated from behind/washed.
▶
Lay the flue pipework with an upward gradient of at least
a 3° to the shaft so that the condensate can drain away.
To protect the sound insulation, observe the following:
▶
Clad the chimney opening in an insulation jacket (mineral
wool).
▶
Do not immure the flue pipework directly at the chimney
opening.
▶
Secure each flue pipe in the installation room to the wall
or ceiling using a pipe clamp that is isolated from struc-
ture-borne sound.

Note
If more power is produced than is needed
(in the building), the product with installed
optional energy meter feeds electrical energy
into the public power grid. If demand is
greater than what is produced and cannot be
covered by the product, the building draws
electrical energy from the public power grid.
