The user is responsible for periodically
checking the pressure of the heating sys-
tem.
If water needs to be added too often, have
the technical support centre check if there
are any leaks in the heating system or the
boiler itself.
Water leaks from the safety valve
Check if the filling cock is closed tightly (see
"Filling the heating circuit" on page 14).
Check on the pressure gauge that the heat-
ing circuit pressure is not close to 3 bar.
Should this be the case, drain a part of the
water from the system through the air relief
valves in the radiators in order to reduce the
pressure to a normal value.
In the case of malfunctions oth-
er than those described above,
shut down the boiler as de-
scribed in section "Shutdown"
on page 13 and call a techni-
cian from the authorised service
centre.
