The final step is selecting the pump for each boiler. In table D below, a pump selection is made for every config-
uration from tables A, B and C. When applying this pump, the maximum allowable distance between water heaters
and tanks is expressed as V
L
. The definition of V
L
is shown in fig.1. From this distance, extra resistance in the
connecting pipes must be subtracted. These resistances are expressed as equivalent lengths and can be found
in table E
Pump codes and maximum distance V
L
