For the 24 BTV flue-gas is removed and
combustion air is brought in by a special
double duct. Double-duct routes can be
completed from the standard parts sup-
plied by the manufacturer for virtually any
sit u a tion. The route must be designed to
enable removal of condensed flue vapours
out of the duct. Special con den sate-dis-
charge elements can be used for that
purpose. If any defects are caused by the
condensation, they will not be cov ered by
the warranty. Due to the variability of local
conditions, the double duct elements are
not in clud ed in the de liv ery or in the boil-
er’s price. Principles for completion of the
routes – see. chapter “Air and flue ducts.”
For the 24 BOV flue-gas is removed by
means open chimney draught. Minimal
required chimney draught in steady stage
is 2 Pa. Connection to the chimney is via
a connecting flue pipe with diameter cor-
responding to flue outlet on the boiler (125
mm). Installation of both the boiler and the
connecting flue pipes with chimney must
comply with valid standards. The stand-
ard's requirements prevent appearance of
adversary effects, such as excessive cool-
ing of the flue gases, penetration of the
chimney wall by humidity, and variability
of chimney draught which would affect the
boiler operation in an undesirable manner.
The connecting flue pipes are not included
in the boiler delivery.
Caution:
Elements reducing the chimney
draught (such as various exchangers for
using the residual heat) are prohibited
from being inserted in the connecting
flue pipe.
The 24 BOV takes combustion air from the
space around it. There must be possibility
of direct space ventilation and sufficient
combustion air supplies comply with valid
standards.
