Burner/boiler combinations have been calculated on the
basis of the burner working at 3% O2.

See the instruction manual provided with the burner for
further information on, burner installation, electrical con-
nections, burner adjustments.

To assemble/disassemble the burners equipped with re-
circulation tube, it might be necessary to remove the latter
before carrying out such operations (strictly comply with the
use and maintenance manual of the burner).
9
Long heads and burner plates are required for the correct
installation and coupling of the burners.
9
If a two stage burner is installed, 1st stage heat input must
not be less than 70% of total heat input. With liquid fuel
burners equipped with 2 nozzles, it is therefore important
to choose the correct first stage nozzle.
9
In Italy, the Decree of the President of the Council of Minis-
ters of the 2nd October 1995 requires that heating systems
with heating power of less than 3 MW use fuel oil with a
sulphur content of less than 0.3 % by weight.
9
Naphtha can only be used in models from 1308 on. With
models 953 to 1074 naphtha fuel can only be used if the
insulation on the boiler door is first protected with a coat
of water soluble, aluminium and silicon oxide based paint.
When running on naphtha, reduce the boiler’s maximum
rated heat output by 20%.
