2. FIRST START-UP
2.1.2. BOILER COMMISSIONING
WARNING
Make sure that the system is correctly
filled.
Proceed with boiler commissioning as follows:
› Power the boiler.
THE START-UP SYSTEM WILL AUTOMATICALLY
ACTIVATE THE SYSTEM AIR RELIEF CYCLE
FUNCTION DISPLAYED ON SCREEN WITH CODE
“F33” (ONLY AT FIRST START-UP WILL LAST FOR
5 MINUTES). When function “F33” is active, the
pump is enabled and the burner start-up request
is disabled. The boiler can work normally only
after completing the operation.
NOTE: Only at the first start-up the system relief
cycle performed by the boiler lasts 5 minutes.
After each water pressure reset the boiler will
automatically perform a reduced system relief
cycle, of 2 minutes. Throughout this function the
display will show the code “F33”. The boiler can
work normally only after completing the operation.
› Open the gas valve.
› 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 not sensed, 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
lines. 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.
