Installer/Servicer notes for the use of Gas oil with Bio blends up to 10%
During the burner installation, check that the gasoil and bio
fuel blends are in accordance with Riello specifications
(please refer to the chapters "Technical Data" and "Guid-
ance for the use of bio fuel blends up to 10%" within the
burner technical manual).
If a Bio blend is in use the installer must seek information
from the end user that their fuel supplier can evidence that
the blends of fuel conform to the relevant standards.
Check that the materials used in the construction of the oil
tank and ancillary equipment are suitable for bio fuels, If not
these must be upgraded or replaced with Bio compatible
parts.
Particular attention should be given to the oil storage tank
and supply to the burner. Riello recommends that existing
oil storage tanks are cleaned, inspected and any traces of
water are removed BEFORE bio fuel is introduced (Contact
the tank manufacturer or oil supplier for further advice). If

the risk of contamination and possible equipment failure.
In line oil filters should be replaced making sure that they are
Bio compatible. Riello recommends a good quality bio com-

Installations 2, 3 and 4 permit operation but make maintenance
and inspection of the combustion head difficult, page 33.
