– The installation where the boiler is
connected to, should be preferably
with an open expansion tank (fig. 9).

to the expansion tank, should have an
adequate diameter according to the
norms in force.
– The heating pump should always be
running during the operation of the
boiler.
– A possible ambient thermostat should
never interrupt the pump operation.
– If the installation is equipped with a
3 or 4 ways mixing valve, it should
always be placed in the opening posi-
tion toward the installation.
– Be assure that the draught regulator
works regularly and that there aren't
impediments, which block the auto-
matic operation of the air gate damp-
er.
