  • Page 2 Congratulations on your selection. Your modulating boiler is electronically adjusted and ignited. • highly efficient • sealed chamber • with steel domestic hot water heat exchanger. The materials used and the regulation system offer you safety, high levels of comfort and energy savings so you can appreciate the maximum advantages of autonomous central heating.
  • Page 3 IMPORTANT The manual must be read carefully in order to use the boiler in a rational and safe manner. It must be stored with care as it may be necessary to consult it in the future. If the unit is trans- ferred to another owner, the manual must accompany the boiler.

  • Page 4: During Use

    DURING USE It is prohibited and dangerous to obstruct, even partially, the air intakes for the ventilation of the room where the boiler is installed (UNI 7129/08). Repairs must only be carried out by Authorised Service Centres using original spare parts. Therefore, in the case of a problem, deactivate the boiler only (see instructions).
