For the nozzle to operate properly, its "return" section must never be completely closed. This is achived by regulating where the
burner is started up for the first time. In practice, when the nozzle is operating at the maximum flow rate, the difference in pressure
between the "delivery" (pump pressure) and "return" (pressure at the return pressure regulator) pressure (running to and from the
nozzle) must be at least 2 ÷ 3 bar.
Example: Pump pressure 20 bar Pump pressure 22 bar
Return pressure 20 - 2 = 18 bar Return pressure 22 - 3 = 19 bar
Return pressure 20 - 3 = 17 bar Return pressure 22 - 2 = 20 bar
