6. SWITCHING OFF THE BOILER

To turn off the boiler, disconnect the electric power supply using the two-pole switch. In the "Off" operating mode
off but the electrical circuits remain powered and the anti-freeze function remains active.

7. FILLING THE SYSTEM

Regularly check that the pressure displayed on the pressure gauge B is 1 - 1.5 bar, with the boiler
cold. If the pressure is too low, turn tap "A" to fill the boiler (figure to side).
A Boiler/system filling tap
B Pressure gauge
Take special care when filling the heating system. In particular, open any thermostat valves in
the system, ensure the water enters slowly in order to prevent the formation of air inside the
primary circuit until operating pressure is reached. Lastly, vent any radiators in the system.
De Dietrich declines all liability for damage deriving from the presence of air bubbles in the primary
exchanger due to the incorrect or imprecise observance of the above.
The boiler is fitted with a hydraulic pressure gauge which prevents the boiler from working if
there is no water.
If pressure drops occur frequently, have the boiler checked by the AUTHORISED TECHNICAL
SERVICE CENTRE.

8. ROUTINE MAINTENANCE INSTRUCTIONS

To keep the boiler efficient and safe, have it checked by the Authorised Service Centre at the end of every operating period.
