Testing

Check that the burner goes off by opening the thermostats (TL);
check that the burner has locked out during operation by opening
the connector (CN) inserted in the probe's red wire, located out-
side the control box.
5.8.2

Ionisation current

The minimum current necessary for the control box operation is
5 µA. The burner gives a much higher current, meaning that
checking is not usually required.
Should you want to measure the ionization current anyway, you
must open the connector (CN1) inserted in the red wire and insert
a microammeter.
