IMPORTANT:
VELA X MB boilers are fitted with FLUE CONTROL to monitor flue draught. This safety device shuts
down the boiler if there is a risk of combustion fume backflow into the room. This device must never be
deactivated. If combustion fumes re-enter the room they may cause chronic or acute intoxication that
can be fatal. If the Flue Control device is changed use only original spare parts.
If the device trips repeatedly contact a Lamborghini Service Centre.
WARNING:
When Summer or Winter mode is selected the ON indicator light comes on
indicating that the boiler is electrically powered.
