When installing the unit, make certain that non-insulated parts in the mounting frame do
not get into contact with the connection terminals. Also observe the lateral connecting

Electrical connection of flame detectors

It is important to achieve practically disturbance- and loss-free signal transmission:

Never run the detector cables together with other cables
– Line capacitance reduces the magnitude of the flame signal
– Use a separate cable

Observe the permissible detector cable lengths

The mains-powered ionization probe is not protected against electric shock hazard.
It must be protected against accidental contact

Earth the burner in compliance with the relevant regulations; earthing the boiler
alone does not suffice

Locate the ignition electrode and the ionization probe such that the ignition spark
cannot arc over to the ionization probe (risk of electrical overloads)
