To calculate the length of
the pipework all the staight
parts, curves, up and down
pipes must be taken into
consideration. The static
suction height is the
distance between the stan-
ding valve and the axis of
the burner pump.
Pressure must not exceed
0,45 bar; if pressure is
greather pump operation
may become faulty, leading
to an increase in mechani-
cal noise and perhaps even
breakage.
