6.2
Combustion adjustment
In conformity with Efficiency Directive 92/42/EC the application of
the burner on the boiler, its adjustment and testing must be car-
ried out observing the instruction manual of the boiler, including
verification of the CO and CO2 concentration in the flue gases,
their temperatures and the average temperature of the water in
the boiler.
Settings carried out in factory
The values in Tab. F refer to 12.50% of CO
2
at sea level, and with
a light oil and ambient temperature of 20°C.

Pump pressure
The pump is calibrated in the factory as shown in Tab. F.

Nozzles
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 manufacturer in the In-
struction and warning booklet should be used.
To set the delivery range within which the nozzle must work, noz-
zle return line fuel pressure must be adjusted.

Start-up, calibration and operation of the burner
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 is sucked from outside, there-
fore, there can be sensitive temperature varia-
tions that can influence the percentage value of
the CO2. It is advisable to adjust the CO2 accord-
ing to the indicated diagram.
E.g. with an external air temperature of 10°C, ad-
just the CO2 to 12.5% (± 0.2%).

WARNING
It is advisable to replace nozzles every year dur-
ing regular maintenance operations.
CAUTION
The use of nozzles other than those specified by
manufacturer and inadequate regular mainte-
nance may result into emission limits non-con-
forming to the values set forth by the regulations
in force, and in extremely serious cases, into po-
tential hazards to people and objects.
The manufacturing company shall not be liable for
any such damage arising from non-observance of
the requirements contained in this manual.
