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 appliance outlet considering that to obtain the data declared mixing with cold water is necessary.
* Efficiencies and weighted NOx refer to the net calorific value.
** For type C63 it is forbidden to install the appliance as it came out of the factory, in configurations that require shared flues in positive
pressure.
