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).

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