INSTALLER/SERVICER NOTES
1. During the burner installation, check that the gasoil and bio fuel blends are in
accordance with Riello recommendations (please refer to the chapters “Technical
Data” and “Guidance for the use of bio fuel blends within the burner technical
manual).
2. 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 EN
standards.
3. Check that the materials used within the oil tank and ancillary equipment are
suitable for bio fuels. If in doubt contact relevant supplier or manufacturer.
4. Particular attention should be given to the oil storage tank and supply to the
burner. Warmflow 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 these
recommendations are not respected this will increase the risk of contamination
and possible equipment failure.
5. Warmflow recommends a good quality bio compatible oil filter at the tank and a
secondary filter are used to protect the burner pump and nozzle from
contamination. The filter sizes must be inline with the technical manual supplied
with the burners.
6. The burner hydraulic components and flexible oil lines must be suitable for bio
fuel use (check with Riello if in doubt).
7. Regularly check visually for any signs of oil leakage from seals, gaskets and
hoses.
8. It is strongly recommended that with Bio fuel use, oil filters are inspected and
replaced every 4 months. More regularly where contamination is experienced.
9. During extended periods of non operation and/or where burners are using oil as
a standby fuel, it is strongly recommended that the burner is put into operation for
short periods at least every three months.
