3.8 - HYDRAULIC CONNECTIONS
ATTENTION!
Before connecting the boiler to the heating
system, thoroughly clean the piping with an
appropriate product compliant with UNI-CTI
8065, in order to eliminate metallic residue
from processing and welding, oil and grease
which could be present and which, reaching
the boiler, could alter its functioning.
Attention!
The fittings of the boiler must not take the
weight of the connecting pipes of the sys-
tem; suitable supporting devices should be
installed to do this.
The dimensions of the supply and return pipes for each boiler
model are given in the DIMENSIONS table.
Check that the system is fitted with a sufficient number of vent
valves.
3.7 - CONNECTING BOILER
TO SYSTEM
Attention!
Make sure that there are no mechanical
tension points while connecting the pipes to
avoid the risk of leakage!
Heating flow and return pipes must be connected to the boiler
at the respective fittings as shown on page 6.
For the dimensioning of the heating circuit pipes, you must take
into account pressure drops caused by radiators, thermostatic
valves, radiator stopping valves and by the configuration of the
system.
The laying of the pipes must be designed taking every neces-
sary precaution to avoid air pockets and to facilitate continuous
degassing of the system.
Make sure that the pipes of the water and heating
system are not used as earthing electrodes of the
electric or telephone system. They are absolutely
not suitable for this type of use. Serious damage
could result for the piping, boiler and radiators in
a short amount of time.
