Selecting the fuel
When selecting the fuel type, take note of the temperature limits of each particular
fuel. The limit values provided here are to be treated as guidelines. Confirm the
actual temperature limits from the fuel supplier.
•
light furnace oil (diesel heating oil) / diesel, summer grade, temperature must
not fall below –5 °C.
•
light furnace oil (diesel heating oil) / diesel, winter grade, temperature must not
fall below –24 °C.
•
light furnace oil (diesel heating oil) / diesel, arctic winter grade, temperature
must not fall below –40 °C.
Confirm the actual temperature limits for the fuel you are using from
the fuel supplier.

If the temperature drops lower than the minimum level, paraffin may form in the
fuel. This may result in the fuel filter and pump being clogged. The clog will
dissolve
only if the fuel temperature rises clearly over 0 °C.
The less aromatic substances the fuel contains, the less deposits will be formed.
Normal furnace oils contain 35–40 % of aromatic substances. In city diesels and
green furnace oils (green diesel heating oil) the concentration is 20 %.
22 GB and 30 GB are designed to work also with future renewable (HVO 15940)
and blended (B10 EN 16734, B20/B30 EN 16709) bio road diesels. This means
the 22 GB and 30 GB are ready for fuels being developed for the future.
