4.5 EMISSIONS

The burners' emission values (according
to EN 676) prove much lower than the
limits laid down by the strictest stand-
ards.
The flame's distribution and its spread
over a large surface means that the burn-
er manages to limit the formation of ther-
mal NOx, the main causes of pollutant
emission.

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 meas-
ure the ionization current anyway, you must
open the connector (CN1) (see wiring diagram
page 8) inserted in the red wire and insert a
microammeter.
