3.5 - INSTALLATION
The boiler does not differ from a normal solid fuel fired boiler;
therefore there are no particular installation codes of practice
other than the applicable national and local safety regulations
and laws.
The installation room must be properly ventilated via
openings, which should have a total surface of
at least 0,5 m².
To facilitate cleaning of the flue circuit, a free
space, not inferior to the length of the boiler,
must be left in front of the boiler.
In addition ensure that the doors can open 90°
without meeting any obstacles.
The boiler can be placed directly on the
floor, because it is equipped with a
self-supporting frame.
Nevertheless, in case of installation in very
damp boiler rooms, it is preferable to fit a
concrete support.
When installation is completed, the boiler
should be in a horizontal position and stable so
as to reduce possible vibrations and noise.
An adequate clearing must be left behind the
boiler for servicing.
INSTALLATION IN BOILER ROOM
Note:
The minimum clearances indicated in figure 9 are compulsory
only for boilers with an output higher than 35 kW.
3.6 - BOILER SYSTEM CONNECTION
Warning!
Make sure the connection of the pipelines
is free of mechanical stresses, in order to
avoid pressure losses!
The C.H. flow and return must be connected to the respective
connections in the boiler, as indicated on page 7.
When determining the size of the CH circuit pipes it is essential
to bear in mind the pressure losses induced by any of the
system’s components and by the configuration of the same
system.
The piping route has to be designed taking all the necessary
precautions in order to avoid air locks and to facilitate the
continuous purging of the system.
Ensure yourself that the system’s piping is not
used as earth clamps for the electrical or
telephone system. They are absolutely
unsuitable for this use. In a short time this could
cause serious damage to the piping, boiler and
radiators.
