To correct length of pipes is calculated by summing up the length of all vertical and horizontal right sections and bends. The static
suction head will be the distance between the non-return valve and the
burner’s pump axle. The depression must not be greater than 0.45 bar; should it be higher, some damages could occur to the
pump, with consequent increase in mechanical noises and ,eventually, a failure.
