INSTALLATION AND USER MANUAL
3.6 Condensation
If the entire flue configuration is more than 15 meters or if it is
expected that condensation will otherwise occur in the flue, e.g.
when a large horizontal flue stretch is present (
H
z
in
figure 3.17
)
a condensate flue must be installed in the system, as supplied by
the companies mentioned in
chapter 1.4.
In these cases always ensure a (minimum) 3° course,
approximately 50 mm per linear meter, on the horizontal parts
of the flue, so that the water can flow away at any time.
The condensate can be collected in, for example, a siphon cup or
a condensate collector (T-shaped) with tap, as shown in
figures
3.16
and
3.17
, parts
(1)
and
(2)
respectively. Place the traps /
catcher at every lowest point in the flue and before the outlet of
the PowerFan. Under no circumstances should the PowerFan be
the lowest point of the flue situation, to prevent problems and
damage to the fan.
Note:
The siphon cup getting dry can cause flue gases to escape.
To stop this from happening, there are liquid-free traps.
