Burner start
Before starting the burner, draw oil in until the filter is completely filled. Then start the burner by
creating a heat demand on the boiler (refer to boiler installation manual). Open the bleed screw
on the oil filter to allow the oil line to bleed fully during the preventilation phase. The negative
pressure (vacuum) must not fall below 0.4 bar. Close the bleed screw when the filter is completely
filled with oil and oil is flowing out without bubbles. Boiler has to maintain in operation at least 15
min. or reach a steady condition of operation, then check the combustion values.

Burner adjustment
Use the pressure regulator to adjust the oil pressure in accordance with the table (tab.1). Monitor
the combustion values continuously as you do so (CO, CO
2
, smoke test). Adjust the airflow
gradually if necessary. Operating on air flap setting.

Oil pressure setting
5 .6 .1
Oil pressure setting
The oil pressure, and therefore burner output, is adjusted using oil pressure regulator (7), see
“Fig. 29”, on the pump.
Sequence to adjust the oil pressure:
–
connect a pressure gauge at point (8).
Turn the regulator screw (7) to:
–
right: to increase pressure.
–
left: to reduce pressure.
–
verify the correct pressure with the pressure gauge.
At the end of adjustment.
–
to disconnect the pressure gauge.
–
to tight the plug (8).
5 .6 .2
Checking negative pressure
The vacuum gauge for checking negative pressure must be connected to point (4). Maximum
permissible negative pressure is 0.4 bar check the oil supply in case those pressures cannot be
achieved. At higher negative pressures, the fuel oil gasifies, which causes pump cavitation in the
pump and ultimately leads to pump damage.
5 .6 .3
Cleaning the pump filter
To be able to clean the filter (H), it is necessary to remove the pump cover.
Check the pump cover seal and replace the gasket if necessary.
