DURING USE It is prohibited and dangerous to obstruct, even partially, the air intakes for the ventila- tion of the room where the boiler is installed (UNI 11071 and related standards); 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).
