Emissions; Final Checks (With Burner Operating); Ionisation Current - Riello RX 360 S/PV Modulating Operation

The flame developed on the surface of the head is perfectly re-
tained and adheres to the mesh when operating at the maximum
setting. This allows modulating ratios as high as 6:1, avoiding the
danger of flashback when modulating is at its minimum.
The flame features an extremely compact geometry, meaning
that there is no risk of contact between the flame and parts of the
generator, consequently eliminating the possible problem of poor
combustion.
The flame's structure means that smaller combustion chambers
can be developed, designed to exploit this particular feature.

Final checks (with burner operating)

 Open the thermostat/pressure switch TL
 Open the thermostat/pressure switch TS
 Disconnect the wire of the ionisation probe
Make sure that the mechanical locking systems
on the various adjustment devices are fully tight-
ened.

Ionisation current

The minimum current necessary for the control box operation is
5 µA.
The burner normally supplies a higher current value, so that no
check is needed.

Emissions

The emission values (in accordance with EN 676) of the burners
are 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 burner manages to limit the formation of thermal
NOx, the main causes of pollutant emission.

The burner must stop

The burner must stop in lockout due to ignition failure
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.
