Notes on safety for the first start-up

The first start-up of the burner must be carried out
by qualified personnel, as indicated in this manual
and in compliance with the standards and regula-
tions of the laws in force.

Adjustment before first firing (gas oil operation)

7.2.1

Combustion head setting

The setting of the combustion head depends exclusively on the
delivery of the burner in the 2
Turn screw 5)(Fig. 29) until the notch shown in diagram (Fig. 30)
is level with the front surface of flange 6).

2 stage burner delivery = 72 kg/h.
If diagram (Fig. 30) is consulted it is clear that for this delivery, the
combustion head must be adjusted using notch 3, as shown in
Fig. 29.
7.2.2

Pump adjustment

No settings are required for the pump, which is set to 12 bar by
the manufacturer.
This pressure must be checked and adjusted (if required) after
the burner has been ignited.
The only operation required in this phase is the application of a
pressure gauge on the appropriate pump attachment.

WARNING
7.3.1

Firing

Set switch 1)(Fig. 31) to "ON".
During the first firing, during the passage from the 1
stage, there is a momentary lowering of the fuel pressure caused
nd
by the filling of the 2 stage nozzle tubing.
This lowering of the fuel pressure can cause the burner to lock-
out and can sometimes give rise to pulsations.
