INSTALLATION AND USER MANUAL
Flue lengths construction - type 2.2
Partial concentric flue - size Ø200 / 130 (See
figure 3.12
)
In this situation, a part of the flue is executed concentrically, after
which the supply and discharge are split and end up separately.
Figure 3.12 serves as a reference for the minimum and maximum
lengths for this construction situation, where
K
+
L
= Total flue length
at which
K
= max. 30 meters
L
= 20 - 2/3 *
K
meters
And

= Terminal
Method
First calculate the length of the concentric part of the flue. Don't
forget to include the extra resistance of bends and any negative
flue lengths. Then read in table 3.2 the maximum length of your
split supply and discharge.
Flue lengths construction - type 2.3
(Partial) Concentric flue - flue size Ø150 / 100 (See
Figure 3.13
)
In this situation, (a part of) the flue is executed concentrically in
Ø150 / 100, after which the supply and discharge are split and
end up separately.
Note:
This flueage situation should be seen as if the fireplace is
being split directly.
If the Ø150 / 100 flue is used, it must be enlarged before it can be
connected to the adapter.
Figure 3.13
serves as a reference for the maximum lengths for
this construction situation, where;
M
= max. 20 m
And
(e)
= Enlarger
(1)
= Transit
Also in this situation it holds that the length of the flue before
the PowerFan must be at least 2 meters i.v.m. possible damage.
