The distance from fl ammable materials
(e.g. PVC, chipboard, polyurethane, syn-
thetic fi bres, rubber and others) must be
suffi cient so that the surface temperature of
these materials does not exceed 80˚C.
Important:
Surface temperature of upper
parts (particularly the side walls and the
cover) of a working boiler might exceed the
ambient temperature by up to 50˚C.
A minimum manipulation (free) space
maintained around the immediate vicinity
of the boiler must be suffi cient for a person
to work on it safely with bare hands and
with common hand tools. Recommended
distances are shown in Fig. 11.
In the 24 KTV and 28 KTV models, com-
bustion gases must be always removed
and fresh air supplied through a special
for this purpose designed dual ducting.
Practically any required dual ducting route
can be constructed from standard com-
ponents supplied by the manufacturer.
The exhaust route must be constructed
in such a way that condensed water va-
pour contained in the combustion gases
can be removed from the ducting. This is
done using special components which can
be built into the exhaust route. Problems
caused by condensate penetration are not
covered by the boiler’s warranty. Because
of the considerable variety of particular
solutions, the dual ducting is not part of
the boiler delivery and is not included in
the price. Principles for route construction
are described in chapter Air supply and
combustion gases removal ducting.
The 24 KOV is designed for combustion
gases to be removed and discharged into
a chimney (through a chimney inlet) with
a minimum stabilised thrust of 2 Pa. The
boiler is connected to the chimney inlet by
a fl ue of a diameter corresponding to the
size of the boiler’s gas exhaust outlet. It is
forbidden to place inside the combustion
gases exhaust ducting any objects which
impair the combustion gasses fl ow (e.g.
various types of heat exchangers to uti-
lise their residual heat). The combustion
gases exhaust ducting is not part of the
boiler accessories.
Construction of the combustion gases ex-
haust ducting as well as that of the chimney
must comply with the requirements of ČSN
06 1610 and ČSN 73 4201. Compliance
with the requirements specifi ed by these
standards will prevent undesirable pheno-
mena from occurring, such as excessive
cooling of the combustion gases, pene-
tration of dampness into brickwork and
fluctuations in the chimney thrust, and
thus prevent undesirable effects on the
boiler’s functioning.
The boiler takes combustion air from the
space in which it is installed. Air must be
supplied in suffi cient quantity in accordance
with applicable regulations.
