(*): it is strictly forbidden to replace the nozzles individually. If necessary, replace the entire manifold.
- 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 water heater outlet
considering that to obtain the data declared
mixing with cold water is necessary.
