4.13.2 Pump priming
– For self-priming to take place, the screw 3)(Fig. 26) of the
pump must be loosened in order to bleed off the air contained
in the suction line.
– The pump can be considered to be primed when the gas oil
starts coming out of 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, and
then repeat the starting operation as often as required. After 5 or 6
starting operations allow 2 or 3 minutes for the transformer to cool.

WARNING
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.
(The pump leaves the factory with the by-pass
closed).
WARNING
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.
Whenever the length of the suction piping ex-
ceeds 20-30 meters, the supply line must be filled
using a separate pump.
