- Fume temperature values refer to an air inlet
temperature of 15°C.
- e data relevant to domestic hot water per-
formance refer to a dynamic inlet pressure of
2 bar and an inlet temperature of 15°C; the
values are measured directly at the boiler outlet
considering that to obtain the data declared
mixing with cold water is necessary.
- e max. sound level emitted during boiler
operation is < 55dBA. e sound level value is
referred to semianechoic chamber tests with
boiler operating at max. heat output, with
extension of fume exhaust system according
to product standards.
