organ located on the pump shaft to break.
 In order for self-priming to take place, the screw 4) on the
pump (Fig. 21) must be loosened to bleed off the air
contained in the suction line.
 Start the burner by closing the remote controls. As soon as
the burner starts, check the direction of rotation of the fan
blade.
 The pump can be considered to be primed when the light oil
starts coming out of the screw 4).
 Close the burner and undo the screws 4).
The time required for this operation depends upon the diameter
and length of the suction tubing.
If the pump fails to prime at first start-up and the burner locks out,
wait approx. 15 seconds, reset the burner, and then repeat the
start-up operation. And so on.
After 5 or 6 starting operations allow 2 or 3 minutes for the
transformer to cool.
Do not light the photocell in order to prevent the burner lockout;
the burner locks out in any case about ten seconds after its start.
The above-mentioned operation is possible

filled using a separate pump.
