FIRING
Set switch 1) (Fig. 21) to "MAN".
During the first firing, the burner must generate a noise similar to
the noise generated during operation.
OPERATION
The optimum calibration of the burner requires an analysis of the
flue gases at the boiler outlet and interventions on the following
points:
• Nozzles
See the information listed on page 16.
• Combustion head
The adjustment of the combustion head already carried out
(page 17) need not be altered unless the 2nd stage delivery
of the burner is changed.
• Pump pressure:
In order to adjust pump pressure, use the relevant screw
5) (Fig. 20). See the information listed on page 16.
• Fan air gate valve
See adjustments page 26 (Servomotor).
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 4) (Fig. 20) 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.
