Start-up, calibration and operation of the burner
5.1 Notes on safety for the first start-up
5.2 Adjustments before first firing (light oil operation)
The optimum calibration of the burner requires an analysis of the
flue gases at the boiler outlet and interventions on the following
points.
5.2.1 Nozzles
See the information listed on page 19.
5.2.2 Combustion head
The adjustment of the combustion head already carried out
(page 21) need not be altered unless the high fire input of the burn-
er is changed.
5.2.3 Pump adjustment
No settings are required for the pump, which is set to 174 PSI 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 connection.
5.2.4 Minimum oil pressure switch
The minimum oil pressure switch (Fig. 28) is factory set to 145 PSI
(10 bar).
If the oil pressure goes down this value in the delivery piping, the
pressure switch stops the burner.
5.3 Burner calibration (light oil operation)
5.3.1 Firing
Set the AZL (Display) in the manual position.
During the first firing, and the change from low to high fire, there is
a momentary lowering of the fuel pressure caused by the filling of
the high fire nozzle tubing.
This lowering of the fuel pressure can cause the burner to lock-out.
5.3.2 Operation
The optimum calibration of the burner requires an analysis of the
flue gases at the boiler outlet and adjustments at the following
points:
Low and high fire nozzles
See the information listed on page 19.
Pump pressure
174 PSI: this is the pressure calibrated in the factory which is usu-
ally sufficient for most purposes.
Sometimes, this pressure must be adjusted to:
145 PSI: in order to reduce fuel delivery. This adjustment is pos-
sible only if the surrounding temperature remains above
0 °C;
5 Start-up, calibration and operation of the burner
WARNING
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.
WARNING
Check the correct working of the adjustment, com-
mand and safety devices.

WARNING
It is advisable to first set the burner for opera-
tion on oil and then for gas.
Turn burner off prior to switching fuels.
