MINI NIKE 24 3E - Technical Data
- Flue temperature values refer to an air inlet temperature of
15°C.
- e data relevant to domestic hot water performance refers
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 ue gas exhaust system according to product
standards.
