Gas leaks
Make sure that there are no gas leaks on the pipe between the
gas meter and the burner.
Gas filter
Change the gas filter when it is dirty.
Measuring circuit for measuring the current detector
The minimum current necessary for the control box operation is
1 µA. The burner normally supplies a higher current value, so that
no check is needed.
Anyway, if you want to measure the ionisation current, you need
to open the connector (CN1) fitted on the red wire and insert a mi-
croammeter.
