Electrical connection of the flame detector
It is important for signal transmission to be almost totally free of
any disturbances or loss:
• always separate the detector cables from the other cables:
– Line capacitance reduces the magnitude of the flame signal.
– Use a separate cable.

• Respect the allowed cable lengths.
• The ionisation probe is not protected against the risk of elec-
trocution. When connected to the electricity supply, the ionisa-
tion probe must be protected against any accidental contact.
• The earthing of the burner must be in accordance with rele-
vant standards; earthing the boiler only is not sufficient.
