Air Adjustment - Ecoflam MAIOR P 150.1 PR Manual Del Usuario

The diagram illustrates the fuel feeding system of these types of burners, which incorporates a by-
pass nozzle with oil flow regulation on its return pipe. The oil supply is varied by acting on the
nozzle through the pressure in the return line. Max. oil supply is therefore reached when the pres-
sure in the pump line is about 22 bar and the return line is fully closed; min. oil supply when the
return line is fully open. Relevant pressure readings in the return line are as follows:
- max. oil supply: 22 bar in the pump.
14-15 bar in the return.
- min. oil supply: 2-3 bar.
Rate of adjustment: 1 to 3 bar.
