3.22 TECHNICAL DATA.
- Flue temperature values refer to an air inlet temperature of 15°C and
delivery temperature of 50°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. The
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.
- * Specific capacity “D”: domestic hot water flow rate corresponding to an
average increase of 30K, which the boiler can supply in two successive
withdrawals.
