3.3 Calculating the length of the flue
3.3.1 Flue construction - type 1
Immediate split supply and removal (See
figure 3.10
)
Maximum discharge lengths for the
When air supply and flue gas discharge are split directly on the
fireplace, the total length of both may cover 40 meters with the
following requirements per part:
L
= max. 20 m
D
= min. 2.0 m
And
(1)
= Terminal
3.3.2 Flue construction - type 2
(Partly) Concentric tube
When working with a concentric tube before the supply and
discharge are split, the total length of supply and discharge can
be 30 meters. In
figure 3.11
to
3.13
. You will see three options
that fall under type 2.
Each option is explained further below
Flue lengths for construction - type 2.1
Maximum length of the concentric tube Ø200 / 130 (
Figure 3.11
)
In this situation, the flue situation is carried out almost
completely concentrically, with the supply and discharge being
split just before the outlet.
Figure 3.11
serves as a reference
for the minimum and maximum lengths for this construction
situation, where
K
= max. 30 meters
And
(1)
= Terminal
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.
