Maintenance instructions

To ensure safety, functionality and optimal efficiency over time, the boiler must be periodically inspected by a qualified
technician. Careful maintenance is always a source of safety and savings in managing the installation.
Important
The appliance is fitted with a hydraulic pressure switch that will prevent the boiler from working if the pressure is
too low. If the pressure decreases frequently, contact a qualified technician for help.

Caution
It is recommended to pay particular attention when filling the
heating system. In particular, open the thermostatic valves if fitted
to the system and let the water flow slowly in order to avoid the
formation of air inside the primary circuit, until the necessary
operating pressure is reached. Finally, bleed any radiant elements
in the system. De Dietrich does not accept any liability for damage
arising from the presence of air bubbles inside the heat exchanger
due to incorrect or approximate observance of the above.
1. The filling knob is light blue and is positioned underneath the boiler.
Proceed as follows to fill the installation:
2. Fill the system until the pressure reaches between 1.0 and 1.5 bar.
3. Close the cock and make sure there are no leaks.
