* DHW values refer to GREEN C.S.I. models.
** Average value among various sanitary running conditions.
*** Estimated with one 90° bend; 16 extensions of 1 meter and a horizontal exhaust of 1 meter (16kW and 25kW),
27 extensions of 1 meter and a horizontal exhaust of 1 meter (35kW).
**** Tested with Ø60-100 concentric - lenght 0,85m - water temperature 80-60°C.
