Preliminary checks

a
WARNING
– Should it be necessary to access the areas in the
bottom part of the appliance, make sure that the
system components and pipes are not hot (risk of
burning).
– Before replenishing the heating system, put on pro-
tective gloves.
Commissioning of the UNIQA REVOLUTION 25 boiler must be car-
ried out by professionally qualified technicians, after which the
boiler can operate automatically. It may, however, be necessary
for the user to start the appliance autonomously without involv-
ing a technician: for example, after a holiday.
First of all check that the gas isolation and water system valves
are open.

– make sure that the operating mode is set to "Stand-by"; if this is
not the case, press the button
been selected
ON
– on the display (1), check that the heating system pressure
when cold is 1-1.2 bar . If this is not the case, open the filling
