7.1.2. Oil Pump Pressure Regulation
Fit a pressure gauge in the connection (see chapter ”Oil Pumps”). Adjust the oil pressure by
turning the pressure regulating screw. The pressure increases by turning the screw clockwise
and decreases counter-clockwise. Oil pump pressure is set at the factory during testing at
approx. 1000 kPa (approx. 10 bar). Pressure setting range is from 700 to 1400 kPa (7 - 14
bar).
When the pressure is changed the oil flow and pressure follow the following formula:
V1
V2
P1
P2
=
V1 = capacity marked on the nozzle
V2 = nozzle capacity at a pressure of P2
P1 = 10 bar gives kg/h according to CEN standard
7 bar gives USgal/h
P2 = pressure to be used
Calculation example
Calculate the nozzle capacity when the nozzle size is 2,37 kg/h (0,6 USgal/h) and pressure is set
at 13 bar.

7.1.3. Calculation of Burner Capacity
If the nozzle size is known, the burner capacity can be calculated as follows:
Example:
Nozzle size 1,87 kg/h (0,5 USgal/h) and pressure to be used 10 bar.
