HYDRAULIC CONNECTION
Correct dimensioning of the boiler and the
heating system, as well as the choice of type of
system to install are the tasks of the installation
technician and/or planner.
If installation of the boiler includes integration
with another pre-existing system using a gas,
diesel, wood-burning boiler, it must be carried
out by qualified staff who will issue documen-
tation on correct installation according to the
standards in force in each country (for example
in Italy pursuant to M.D. 37/2008 and pursuant
to the standard UNI 10412-2)

It is important to wash the entire system
before connecting the boiler to eliminate
deposits and residue in compliance with
Standard UNI 8065 (water treatment in heat-
ing systems for residential use).
Install shut-off valves upstream of the boiler
to insulate it from the rest of the system if
any movement or maintenance operation is
necessary.
The hydraulic system must work with pressure
between 1 and 1.5-2 bar hot on a closed heating
circuit.
N.B.: The boiler should NOT be installed to
replace a heating stove installed with an open
circuit without adapting the expansion system,
making it a closed circuit.
