- Flue temperature values refer to an air inlet temperature of 15°C.
- The data relevant to domestic hot water performance 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.
- The max. sound level emitted during boiler operation is < 55dBA.
