Elimination of the fault:
Check that the gas service cock is in the On position and that the air present in the piping has been vented. Press the
reset key to restore correct boiler operation.
If the cut-off device operates repeatedly (a maximum of 3 times), causing boiler shutdown, do
not try to relight the boiler your self. Contact your nearest VIADRUS authorized After Sales

If the boiler goes into lock-out and/or the leds continue to flash repeatedly or remain illuminated
do not try to reset the boiler yourself. Contact your nearest VIADRUS authorized Afters Sales
