Atomisation of the oil is by mean of three outer nozzles and one central nozzle. The pump pressure
is set at 25 Bar, the two pressure regulators controlling the pressure to all four nozzles are set at 10
Bar. On Low fire V1, V2 and V3 are open, V4 is closed. This allows oil to pass through all four
nozzles at a pressure of 10 Bar. On High fire, V1,V2, V3 and V4 are opened, oil at 10 Bar flows
through the centre nozzle, oil flows through the three outer nozzles at 25 Bar through V4 bypassing
the pressure regulator through V3.
