In the KTV models, combustion gases
must always be removed and air supplied
through a dual ducting specially designed
for this purpose.
Horizontal ducting sections must have a
gradient allowing condensate to be dischar-
ged to the outside space or to condensate
removal components. This is achieved by
combining elbows with straight compo-
nents which will result in a gentle slope of
the straight section. Vertical sections must
be always fi tted with condensate removal
components. These must be whenever
possible installed in an immediate vicinity
of the boiler’s combustion gases discharge
outlet. Defects caused by condensate pe-
netrations are not covered by the boiler’s
warranty.
Air supply/combustion gases
removal methods (acording to EN
483) and permitted ducting route
lengths
Unless stated for the following dual du-
cting route design methods and their
termination outlets otherwise, the ducting
route lengths (from the boiler connection
point to the termination outlet) must be as
specifi ed in Table 1 below.
Note:
As 1 Em is regarded either 1 m of
straight section or one 90˚ elbow.
Important:
:
When the lengths specifi ed
in Table 1 are exceeded, it is necessary
to remove the combustion gases diffuser
(aperture) from the fan outlet (Fig. 17).
The following methods of air supply and
combustion gases removal are permitted
for this boiler:
Method C
12
– horizontal routes with ho-
rizontal termination outlets discharging
combustion gases to free space.
When using separate ducting (80 mm) in
horizontal routes with horizontal termina-
tion outlets, the air supply inlet and the
combustion gasses outlet from the same
boiler must be situated inside a square of
a 0.5 m side.
An example of a dual horizontal ducting
route – method C
12
(according to ČSN EN
483) is illustrated by Fig. 18.
Method C
32
– vertical routes with vertical
termination outlets into free space. For
termination outlet of separate ducting,
the same applies as for method C
12
. An
example of a dual vertical ducting route
– method C
32
(according to EN 483) is
illustrated by Fig. 19.
