4.3 TECHNICAL DATA.
- 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 neces-
sary.
- 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.
- * Eciencies refer to the net caloric value.
- e weighted NOx value refer to the net caloric value.
