3.16 - CONDENSATE DRAIN
Avoid the condensate stagnation inside the combustion products
evacuation system, (for this reason the evacuation duct must
have an inclination toward the drain of at least 30 mm/m (3/8 in. /
ft) except the liquid column, inside the condensate siphon, which
needs to be filled with water after installation: its minimum height,
when all the fans are in operation, must be at least 25 mm (1 in.).
In order to avoid ice formation while the boiler is operating,
which can cause the stop of the boiler, the whole condensate
evacuation system has to be well insulated. It is forbidden to
evacuate the condensate through a gutter: risk of ice forming
and corrosion.
The condensate, before being evacuated to the sewer, has to
The outlet of the condensate drain pipe will be on the same
side of the smoke chamber, passing below the smoke chamber.
Before commissioning the boiler fill the con-
densate siphon with water, from the dedicated
filling-up plug.
* Min. height of the condensate column, with all fans
operating at max. speed, requested by the EN stan-
dards.
** Min. height of the condensate column, with all fans
operating at max. speed. In the case it is not possible
to create a 100 mm basement, install the boiler on the
floor and foresee a min. 100 mm well to lodge the siphon.
be neutralized, neutralisation which can be obtained by mixing
the drain water coming from washing maschines, dish washing
maschines, etc., which normally have a basic pH.
The connection to the sewer will be through a visible drain. Given
the high acidity degree (pH 3 to 5) only plastic material can be
used for the condensate evacuation pipes. Moreover it must be
dimensioned and constructed so as to allow the correct out-flow
of drains, preventing any bottleneck and any leakage.
