Notes on safety for the first start-up

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
2
concentration in the flue gases,
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
2
at sea level (1013 hPA)
and with light oil and room temperature of 20°C, and combustion
chamber pressure of 0 mbar.

Nozzles recommended
Steinen
type 60° H;
Danfoss
type 60° H;
Delavan
type 60° W.
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
WARNING
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
The combustion air must be sucked in from out-
side, there therefore might be considerable varia-
tions in temperature that can influence the CO
2
percentage value.
It is therefore advisable to regulate the CO
2
on the
basis of the graph shown. E.g.: outside air temper-
ature 10 °C, regulate the CO
2
to 12.5% (± 0.2%).

WARNING
To achieve CLASS 3 (EN267:1999) emissions,
hollow-cone nozzles have been used
WARNING
It is advisable to replace nozzles every year dur-
ing regular maintenance operations.
CAUTION
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
in extremely serious cases, into potential hazards
to people and objects.
The manufacturing company shall not be liable for
any such damage arising from nonobservance of
the requirements contained in this manual.
