- Fume temperature values refer to an air inlet temperature of
15°C.
- The 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 nec-
essary.

- The max. sound level emitted during boiler operation is < 55dBA.
The sound level value is referred to semianechoic chamber tests
with boiler operating at max. heat output, with extension of flue
gas exhaust system according to product standards.
- * Efficiencies refer to the net calorific value.
- The weighted NOx value refer to the net calorific value.
