4.
Remove the draining screw and rinse the oil control through with fuel oil from the tank until clear oil emerges
at the point of drainage. In the case of models with no draining screw, the fuel oil must be removed from the
interior of the oil control by means of a suction pump. Note: use only a soft pipe inside the oil control to
prevent damage to any of the interior components.
5.
If water should be found inside the oil control, it is advisable to remove the pipe between the oil control and
the burner and to clean it. After the above-mentioned operations have been carried out, a trial run lasting at
least 15 minutes must be made with the device set first at low and then at high.
Should this trial run not prove satisfactory for reasons of the oil flow or the proportions between the fuel and
the combustion air, the oil flow is to be adjusted to the viscosity of the oil and/or the available flue draught or,
if necessary, other more far-reaching adjustments made in the oil control itself. The measures to be taken in
this case are described under «Oil Flow Adjustment».
Removal of the draining screw (Diagram 7) and rinsing
of the oil control with fuel oil from the tank until only
clean oil emerges at the point of drainage. In the case
of models without a draining screw, the fuel oil inside
the oil control must be removed by means of a suction
pump.
Note: use only a soft pipe inside the oil control to
prevent damage to any of the interior components.
Removing the draining screw.
