Start-up, calibration and operation of the burner

6.1

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-
WARNING tions of the laws in force.
6.2

Combustion head adjustment

Pay attention to moving parts.
Danger of crushing of limbs!
The air damper servomotor 4)(Fig. 8, page 13), beyond varying
the air output according to the output demand, through a leverage
varies the combustion head adjustment.
This system allows an optimum adjustment also at minimum fir-
ing rate.
Similarly to servomotor rotation, it is possible to vary the opening
of the combustion head moving the tie-rod on the holes (1-2-3),
(Fig. 19).
The selection of the hole 1-2-3)(Fig. 20) to be used is determined
according to the maximum output requested (Tab. I).
In the factory, the hole is adjusted for the maximum stroke
(hole 3).
In case in which, with boilers with high back pressure, also with
damper completely open, the air output is not enough, it is possi-
ble to carry out a calibration different to the one indicated by the
Tab. I, moving the tie-rod on the following higher hole, increasing
the opening of the combustion head and the air output.
