Notes on safety for the first start-up

The first start-up of the burner must be carried out
by qualified personnel, as indicated in this manual
and in compliance with the standards and regula-
tions of the laws in force.
WARNING
Check the correct working of the adjustment, com-
mand and safety devices.
WARNING
8.2

Combustion setting

In conformity with Efficiency Directive 92/42/EEC the application
of the burner on the boiler, adjustment and testing must be car-
ried out observing the instruction manual of the boiler, including
verification of the CO and CO
their temperatures and the average temperature of the water in
the boiler.
To suit the required appliance output, choose the proper nozzle,
adjust the pump pressure, the position of the mixing unit, the flue
gases recirculation slotted holes, and the air damper adjustment
in accordance with the following schedule.
The values shown in the table are measured on a CEN boiler (as
per EN 267), and they refer to 13% CO
and with light oil and room temperature of 20°C, and combustion
chamber pressure of 0 mbar.

To achieve CLASS 3 (EN267:1999) emissions,
hollow-cone nozzles have been used
WARNING
The burner complies with the emission requirements of the EN
267 standard.
In order to guarantee that emissions do not vary, recommended
and/or alternative nozzles specified by Riello in the Instruction
and warning booklet should be used.

Operation
The combustion air must be sucked in from out-
side, there therefore might be considerable varia-
tions in temperature that can influence the CO
percentage value.
WARNING
It is therefore advisable to regulate the CO
basis of the graph shown. E.g.: outside air temper-
ature 10 °C, regulate the CO

It is advisable to replace nozzles every year dur-
ing regular maintenance operations.
WARNING
The use of nozzles other than those specified by
Riello S.p.A. and inadequate regular maintenance
may result into emission limits non-conforming to
the values set forth by the regulations in force, and
CAUTION
in extremely serious cases, into potential hazards
to people and objects.

any such damage arising from nonobservance of
the requirements contained in this manual.
