Electrical connection of flame detectors

It is important to achieve practically disturbance- and loss-free signal transmission:
∂
Never run detector cables together with other cables
– Line capacitance reduces the magnitude of the flame signal
– Use a separate cable
∂
Observe the permissible length of the detector cables (see Technical data)
∂
Insulation resistance
– Soiled detector holders reduce the insulation resistance, thus supporting
creepage currents
∂
Earth the burner in compliance with the relevant regulations; earthing the boiler
alone does not suffice
