Positioning probe - electrode

Before fixing the burner to the boiler, check from
the opening of the blast tube that the probe and
the electrode are correctly positioned, as in
Fig. 16.
WARNING
If, in the previous check, the position of the probe or electrode
was not correct, is necessary:
 remove the screw 1)(Fig. 15)
 extract the inner part 2)(Fig. 15) of the head, and adjust
them.
Do not rotate the probe: leave it as in Fig. 16.

Installation
For boilers with front flue passes 13)(Fig. 17 at page 24), or flame
inversion chambers, a protection in refractory material 11) must
be inserted between the boiler refractory 12) and the blast tube
10).
This protection must not compromise the extraction of the blast
tube.
For boilers with a water-cooled frontal, a refractory cover is not
necessary 11)-12)(Fig. 17), unless expressly requested by the
