Figure 16-7 - Position of electrodes on the burner
16.5 - Correct positioning of ignition and
ionisation electrodes
For the appliance to work well, it is essential that the electrodes
are correctly located (refer to Figure 16-7):
- the distance between ignition electrodes “A” and “B” must
be between 2.0 and 2.5 mm;
- the distance of ignition electrodes “A” and “B” from the
surface of the burner must be between 5 and 5.5 mm;
- the distance of ionisation electrode “C” from the surface of
the burner must be between 5.5 and 6.5 mm.
For accurate location of the electrodes it is good to use sliding
calipers to respect the tolerances given in Figure 16-7.

16.4.1 - Heat insulation devices
The heat insulation devices must be checked once a year
and replaced if broken or damaged. See figure 16-6 in which
the heat insulation devices (details “C” and “E”) are shown
disassembled from the heat exchanger and burner.
To replace them, refer the to instructions provided with the
spare part.
