1.1.16. CONDENSATE DRAIN
FILLING THE CONDENSATE DRAIN SIPHON
Before starting the boiler you have to fill the
condensate collection siphon in order to avoid fuel
reflux through the siphon.
Fill the condensate collection siphon as follows:
› Unscrew the screw “P” (fig. 1), extract the siphon
and fill it with water up to the highest point “T”
(fig. 1);
› Connect the adequately prepared flexible
condensate drain tube to a disposal system
(it is necessary to neutralise the condensate
if the material out of which the canal system
where the condensate arrives is composed
presents a corrosion risk; please see paragraph
‘CONDENSATE NEUTRALISER’). The condensate
can be drained directly in the sewerage system
by inserting an easily serviceable siphon.
WARNING
After the first months of operation of the
device, it is recommended to clean the condensate
collection siphon from any deposits deriving
from the first transit of the condensate inside the
technical components of the boiler. Such deposits
might cause a malfunction of the siphon.
CONDENSATE DRAIN
The boiler produces a significant quantity of
condensate during operation. This condensate has
an acid pH of 3-5. Observe the national standard in
force and the local regulations for the disposal of
the condensate produced by the boiler.
The designer, according to the power of the system
and the intended use of the building, is bound to
evaluate the acceptance of systems in order to
neutralise the acid condensate.
The system must be performed so as to avoid the
freezing of the condensate. Before putting into
operation the device, check the correct evacuation
of the condensate.
WARNING
Before connecting the condensate
collection siphon to the drain tube, check that
the slope of the boiler is ensured according to the
indications from chapter ‘INSTALLATION OF THE
BOILER’.
WARNING
Correctly connect the condensate
collection siphon of the boiler to a draining system
by adding the slope to the drain of the condensate
of the fume exhaust duct. Where possible, it is
recommended to perform such connection by
means of a collection glass in order to check the
correct discharge of the condensate avoiding
stagnations that might cause dangerous returns of
the condensate to the boiler.
In order to connect the condensate draining to
the draining system, use only corrosion-resistant
materials with an adequate diameter.
