ADVANTAGES FOR SERVICE TECHNICIANS

The CLAS B boiler is easy to maintain. Thanks to frontal access for all components, the boiler is able to offer

reduced maintenance times and most of the work can be performed without using tools.

The two "stratification" storages ensure high performaces for long time and don't need any maintenance

work due to deposit of limestone on internal parts.

Furthermore, when an operating anomaly occurs, the display shows the corresponding error code which may

then be relayed to the Assistance Service so that the technician is well prepared with the necessary material

when coming to repair the appliance.
