ECOLOGICAL OIL BURNERS
WARNING
The transition from normal fuel oil to ecological fuel oil requires:
• The tank to be emptied of normal fuel oil.
• Cleaning of the tank and the pipes that carry the fuel oil to the burner.
• Application of a filter if there is not one already on the burner fuel line with a filtering grade of 0.3 mm
maximum.
If this is not done, Riello S.p.A. declines all liability if the burner fails to work properly or wears out prema-
turely.
NOTES
These burners are the result of careful study that allows them to be used with ecological fuels as well; oils,
that in certain temperature and speed conditions, are particularly aggressive for the vital parts of the burn-
er.
The objective has been achieved with the reduction of the transiting speed in some of the parts and an ap-
propriate choice of materials (in particular surface treatments) as well as a redefinition of the backlashes
and coupling tolerances.
The burners for ecological oils are very different from normal fuel oil burners because they have a separate
pump (worked by its own motor at 1400 rpm) and for the presence of double filtration between pump and
nozzle.
