1.1.18. FUME EXHAUST FITTINGS
WARNING
In order to ensure proper operation and
efficiency of the device you have to connect the water
heater fume exhaust fitting to the fume exhaust
duct using appropriate polypropylene flue fittings
for condensing water heaters. It is recommended to
install discharge systems approved by Radiant.
WARNING
You cannot use traditional flue fittings for
the discharge ducts of the condensing water heaters,
nor vice versa.
WARNING
For fumes exhaust and condensate
collection, please follow the technical standards in
force.
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.
› For all air suction ducts, with regard to the
air path, you should provide an uphill slope
(towards the water heater) so as to avoid the
protrusion inside the duct of rain water, dust or
foreign objects.
› 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.
› In order to discharge the fumes through a fumes
exhaust duct carefully follow the technical
standards in force.
› Make sure that the discharge tube doe 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 opposite internal wall of the chimney or of
the fumes exhaust duct (fig. 1).
