5.13.2 Priming pump
Before starting the burner, make sure that the
tank return line is not clogged.
Obstructions in the line could cause the seal-
ing organ located on the pump shaft to break.
WARNING
Make sure that the valves on the suction line
are open and that there is fuel in the tank.
In order for self-priming to take place, the screw 3)(Fig. 31) of the
pump must be loosened in order to bleed off the air contained in
the suction line.
Select the fuel by positioning the selector (Fig. 31) to "OIL".
Start the burner by closing the remote control, with the selec-
tor 9)(Fig. 5 on page 12) in position "1".
The pump can be considered to be primed when the light oil
starts coming out of the screw 3)(Fig. 31).
Stop the burner: position the selector 9)(Fig. 5 on page 12)
in the "OFF" position and tighten the screws 3) of the pump.
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, and
then repeat the starting operation as often as required. And so
on.
After 5 or 6 starting operations allow 2 or 3 minutes for the trans-
former to cool.
Do not illuminate the flame sensor or the burner will lock out; the
burner should lock out anyway about 10 seconds after it starts.

The above-mentioned operation is possible be-
cause 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.
Whenever the length of the suction piping ex-
ceeds 20-30 meters, the supply line must be filled
using a separate pump.
5.13.3 Pump motor rotation
Check that the rotation takes place in an anti-
clockwise direction, as shown in Fig. 33.
