Y must be kept as lower as possible in order to avoid cavitation. Anyway Y< 4 m.

1301-1800
1801-2200
e.g.: altitude 1100m Theoretical H = 1m actual H 2m, Corrected H for suction 2 + 1 = 3m Corrected H for charging 2 - 1 = 1m.
Choose the Ø of the piping from the table, based on the length expanded between the tank and pump. If corrected H for suction
exceeds 4m; make provisions for a transfer pump (max. pressure 2 bar).

burners powered by 50 Hz mains
electricity; in case of 60 Hz power,
divide the relevant lengths by 1.5.
