radius of r > 3d.
The safety valve has to have a label and the following information on it:
the manufacturer’s name;
the safety valve’s type tag /year of inspection tag;
the nominal flow;
information saying what thermal output the safety valve is set to;
the highest relief pressure, that is 3 bars.
It is mandatory to inspect the operational functionality in certain periods and to have
recalibration done by the certified companies. These obligations are conducted in
accordance with the law of each country where the boiler is assembled. It is mandatory to
keep the written document containing information on the last calibration of the safety
valve.
Install at least one other pressure relief valve on the return line.
Along with the pressure relief valve, the breather valve belongs to the same safety
group.
The automatic air vent (Picture 5)
has to be installed on the highest point of the boiler
and directly without any piping or any other elements between. For this purpose, there is
a specially designed outlet. It is strictly forbidden to reduce this outlet’s diameter in any

The heating pump plays a vital safety function and it is factory-connected to an
electric power supply through automatic controls due to safety reasons. When
the water temperature in the boiler reaches the critical value of 86 degrees
Celsius, the fan stops working, but the pump necessarily turns on to exchange
water through radiators
.
Installing a charging and discharging tap is done at the lowest point of the
system. On the boiler itself, there is a charging and discharging port. Charge the
installation slowly in order to irradiate the system. While the installation is being
charged, check if there aren’t any leaks in the central heating system.
3.3. The operating space and position of the UNI 25 water boiler
While choosing a place where to position the boiler, you should pay attention to the
following details:
The boiler has to be as close to the chimney as possible, the supply of fresh air for
combustion should also be as close as possible.
If possible, the boiler needs to be in the biggest, central room of the heated object for
the greatest effect of heating by radiating.
The device mustn’t ever be installed in the bedroom neither in the room inseparable
from the bedroom by a door.
