Preparation for start up
5.1
Combustion head setting
Loosen the screw 1) and turn the graduated sector 2) according diagrams Fig. 16. The system
allows an optimal setting even at a minimum firing rate. Combustion head opening can be var-
ied by moving the lever onto holes from 0 to 6, Fig. 14.
The choice of the hole (0 - 6) to be used is decided on the basis of diagram (Fig. 16) against the
required maximum output. Setting is pre-arranged in the plant for the maximum power (hole 6).
When dealing with boilers featuring a strong back pressure, if air delivery is insufficient even
with the damper fully open, you can use a different setting to that illustrated in diagram (Fig. 16)
- do this by moving the lever onto the next highest hole numerically speaking, thus increasing
the combustion head’s opening and hence air delivery.
For operation on flame-reversal boilers, gas pipes must be adjusted to hole
position 4, see Fig. 15.
5.2
Position of electrodes (Fig. 17)
Make sure that the electrode and
the probe are positioned as shown
in Fig. 17.
