code HC0048.10GB ed.B-1811
AKY
* Abbreviation compliant with reg. EU/811/2013.
1 The boiler is supplied as standard with B23P terminal; other configurations are possible using accessories.
2 Reg. EU/813/2013 art.2 point 20. It is calculated starting from the weighted average of useful efficiency to the rated heat output and of the useful
efficiency at 30% of rated heat output, expressed in %. For calculation purposes, the efficiency value is referred to the higher calorific value [Hs].
3 Value referred to cat. H (gas G20) with Burner for Switzerland setting. For further details refer to page 34 table 6.2 (gas settings).
4 CO and NOX values refer to the average weighted value of emission between maximum and minimum rated heat output according to the product
standard. Values referred to cat. H (gas G20).
5 The boiler is supplied as standard with C63 configuration; other configurations are possible using accessories available from our catalogue.
6 AKY100 for Switzerland is weakened: Burner heat output [Hi] [72/45°C] MAX: 92 kW and MIN: 20.5 kW.
