5 - INSTALLATION
5.7 - Condensate drain
There is a siphon inside the appliance for the evacuation
of condensate (see figures 3-2 and 3-4 detail “40”) and to
prevent combustion products from escaping, whose end
corresponds to the pipe “B” in figure 5-5. This termination
must be conveyed into an anti-odour siphon (figure
5-9 detail “G”) to prevent bad odours returning into the
environment (the anti-odour siphon “G” is supplied on
request). The tank “A” is mounted in the factory as indicated
in figure 5-5, the exhaust pipe “F” is mounted in the factory
as indicated in figure 5-6. In particular, the condensate
discharge must comply with the following:

for room used for residential purposes and for office
with more than 10 users, it can be connected to the
domestic waste disposal plant by means of appropriate
siphon with disjunction capable of preventing the
pressurisation of the system (siphon prepared within
appliance) and to prevent the return of bad odours
from the sewer (detail “G” in figure 5-9). If the room
used for office purposes has less than 10 users, before
connection with the domestic waste drain, a condensate
neutraliser is good practice (see section 9 for the value of
acidity of the condensate and the quantities).

be connected to a plastic (not copper) drain pipe with a
minimum internal pipe diameter equal to or greater than
13 mm;

be installed in a way to prevent the liquid from freezing;
therefore pay attention to any external passings. It is
prohibited to drain into gutters or drainpipes;

to slope continuously towards the drain point, avoid high
points, which could pressurise the pipe;
5.8 - Safety valve
The appliance is protected against overpressures by a
safety valve calibrated to 10 bar (see figures 3-1 and 3-4
detail “28”). The safety valve drain (detail “C” in figure
5-5), along with the condensate drain (detail “B” in figure
5-5) must be conveyed to a pipe “F” (see figure 5-6) with
minimum internal diameter of 13 mm. The pipe “F” must be
then taken to the anti-odour siphon (detail “G” figure 5-9).
This drain with siphon is used to prevent overpressures if
the valve is opened and makes it possible for the user to
check the eventual intervention. The pipe “F” in figure 5-6
is supplied by standard along with the tank “A” in figure
5-5. The anti-odour siphon “G” in figure 5-9 is provided on
request.
ATTENTION !!! If not connected to the drain,
whenever the safety valve should intervene, it could
cause damage to persons, animals or objects.
