WARNING
Make sure that the system is correctly
filled.
Proceed with boiler commissioning as follows:
› check that the gas tap is closed;
› power the boiler;
› make sure the circulator is not blocked;
› if it is blocked, wait that the circulator performs
the automatic unlocking function (3 minute
duration);
› if the circulator appears to be still blocked,
reactivate the automatic unlocking function of
the circulator (additional 3 minutes) by shutting
off the power supply and then restoring it.
› After completing the above mentioned
operations, open the gas tap.
› Use the button ‘
’ to select the desired
operation mode. If the symbol is displayed fixed,
it means that the function was activated.
› the burner will start as soon as the thermostat
contact is closed;
› if the flame is missing the board will repeat the
start-up operations after post-ventilation (20
seconds).
› You might have to repeat the start-up operation
several times to release all air inside the gas
tube. Before repeating the operation, wait at
least 5 seconds from the last start-up attempt
and unlock the boiler from “E01” error code by
pressing the Reset ‘
’ key.
