5.13.2 Pump priming
– In order for self-priming to take place, one of the screws
3)(Fig. 20 - Fig. 21) 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 and with switch
1)(Fig. 26 on page 26) in the "ON" position. The pump must
rotate in the direction of the arrow marked on the cover.
– The pump can be considered to be primed when the fuel starts
coming out of the screw 3). Stop the burner: switch 1)(Fig. 26
on page 26) 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, and then repeat the starting oper-
ation as often as required. After 5 or 6 starting operations allow 2
or 3 minutes for the transformer to cool.
Do not illuminate the photocell or the burner will lock out; the
burner should lock out anyway about 10 seconds after it starts.
In case of use with gas oil containing up to 10%
Bio blend, it will be essential to use flexible oil
lines suitable for bio fuel use.

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).
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 exceeds 20-30 me-
ters, the supply line must be filled using a sepa-
rate pump.
