6.13.2 Pump priming
– Before starting the burner, make sure that the tank return
line is not clogged. Obstructions in the line could cause
the sealing organ located on the pump shaft to break.
– In order for self-priming to take place, one of the screw
3)(Fig. 22) of the pump must be loosened in order to bleed off
the air contained in the suction line.
– Start the burner by closing the control devices with switch
1)(Fig. 27) in the "MAN" position. As soon as the burner starts,
check the direction of rotation of the fan blade, by looking
through the flame inspection window 25)(Fig. 4 on page 10).
– The pump can be considered primed when the light oil starts
coming out of the screw 3). Stop the burner: switch 1)(Fig. 27
on page 24) set to "OFF" and tighten the screw 3).
The time required for this operation depends upon the diameter
and length of the suction tubing. If the pump fails to prime at the
first starting of the burner and the burner locks out, wait approx.
15 seconds, reset the burner, as often as required. After 5 or 6
starting operations allow 2 or 3 minutes for the transformer to
cool.
Whenever the length of the suction piping exceeds 20-30 meters,
the supply line must be filled using a separate pump.

The a.m. operation is possible because the pump
is already full of fuel when it leaves the factory. If
the pump has been drained, fill it with fuel through
the opening on the vacuum meter prior to starting;
otherwise, the pump will seize.
