14 - INSTALLATION - Air intake and flue exhaust ducts
14.1.2 - Split system
The appliance is standard supplied with fittings to connect
to the flue exhaust and air intake. To install, proceed as
shown in figure 14-2.
1.- put duct “D” in fitting “A” and secure it using the
tightening clamp in fitting “A”;
2.- reducer “C” is standard assembled on fitting “B”;
3.- put duct “E” into reducer “C”, being sure that the gasket
in reducer “C” is positioned correctly;
It is mandatory to install polypropylene ducts that are
more resistant to condensate formation on the “B” flue
exhaust side.
Take particular care in installing the ducts in the parts
that cross the wall towards the outside; it must always
be possible to do normal maintenance operations.
Therefore, install the pipes in a sheath in order to be able
to slide them out.
The horizontal sections must always have a slope of at
least 2% towards the condensate drain devices.
The appliance is already equipped with a condensate
collector, which must be joined to an exhaust pipe (see
section 12).
ATTENTION !!! This condensate drain is
designed to make all the liquid produced by an
individual appliance flow out. Should several
appliances be installed, provide each with its own
condensate drain.
The flue exhaust/air intake system can be extended up to
a maximum distance as instructed in section 18. Each 90°
curve has a loss equivalent to what is described in section
18.
ATTENTION !!! The flue exhaust outlet must be
appropriately protected against the effects of the wind.
ATTENTION !!! Mechanically secure the
joints between the various exhaust and intake duct
components using fixing or equivalent systems. See
figure 14-4.
ATTENTION !!! The temperature of the exhaust
pipe during operation can reach 90°C. If they cross
through walls that are sensitive to these temperatures,
put in a protective heat insulating sheath.
ATTENTION !!! If the air intake and flue exhaust
outlets are positioned on the same wall, they must be
at least 1 metre away from each other.
ATTENTION !!! The exhaust and intake ducts
must be appropriately supported via rigid brackets
positioned no more than 1 m from each other. The
brackets must be secured to rigid walls that can
support the weight of the duct itself.
