- Fume temperature values refer to an air inlet
temperature of 15°C.
- The 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.
- * Efficiencies refer to the lower heating value
