Then, from the pump, the pressurised oil is driven to the nozzle: a part comes out from the nozzle while the othe part goes back to the pump.
- Page 23 PART II: INSTALLATION Connecting the oil flexible hoses to the pump To connect the flexible oil hoses to the pump, proceed as follows, according to the pump provided: remove the closing nuts A and R on the inlet and return connections of the pump; screw the rotating nut of the two flexible hoses on the pump being careful to avoid exchanging the lines: see the arrows marked on the pump.

During commissioning operations, do not let the burner operate with insufficient air flow (danger of formation of carbon monoxide); if this should happen, make the fuel decrease slowly until the normal combustion values are achieved.
- Page 28 PART III: OPERATION To adjust the air flow rate in the high flame stage, loose the RA nut and screw VRA as to get the desired air flow rate: moving the rod TR towards the air damper shaft, the air damper opens and consequently the air flow rate increases, moving it far from the shaft the air damper closes and the air flow rate decreases.
