1.1.17. FUME EXHAUST FITTINGS
WARNING
In order to ensure proper operation and
efficiency of the device you have to connect the boiler
fume exhaust fitting to the fume exhaust duct using
appropriate polypropylene flue fittings for condensing
boilers. It is recommended to install discharge
systems approved by Radiant.
WARNING
You cannot use traditional flue fittings for
the discharge ducts of the condensing boilers, nor
vice versa.
WARNING
Ducts and fume exhaust duct must be
adequately sized, designed and built according to the
standards in force. They must be made of material
adequate to the purpose, with special corrosion
resistance, smooth on the inside and with hermetic
sealed type. In particular, the junctions must have
a condensate guard. Moreover, provide adequate
condensate draining points, connected to the siphon
in order to avoid that the condensate produced in the
chimney goes into the generators.
› For all discharge ducts, with regard to the
fumes path, you should provide an uphill slope
(outwards) so as to favour the reflux of the
condensate towards the combustion chamber,
suitably realized to collect and drain acid
condensate.
› In case of horizontal co-axial system installation,
correctly place the horizontal co-axial terminal
suitably realized to respect the slopes inside the
fumes duct and to protect the air suction duct
from adverse weather conditions.
› If a vertical fumes duct is installed, insert a
condensate collection siphon at the base of the
duct connected to the sewerage system of the
location.
› In order to discharge the fumes through a fumes
exhaust duct carefully follow the technical
standards in force.
› Make sure that the discharge tube does not
protrude inside the fumes exhaust duct, stop
before it reaches the inner surface of the latter.
› The discharge duct must be perpendicular with
the wall of the fumes exhaust duct.
