Fuel quality requirements for auxiliary heater
If the heater is run from a separate fuel tank, comply
with the following rules.
f ambient temperatures over 0 °C;
Use diesel fuel according to DIN EN 590.
If ambient temperatures from 0 °C to -20 °C;
Use winter diesel fuel according to DIN 590.
If ambient temperatures from -20 °C to -40 °C;
Use Arctic diesel or Polar diesel.
NOTE!
- Used oil is not allowed.
- After refuelling with winter or cold diesel or the
listed blends, the fuel pipes and the metering
pump must be filled with the new fuel by letting
the heater run for 15 minutes.
- Volvo does not recommend mixing Kerosene with
diesel due to unstable combustion which causes
decrease of durability of auxiliary heater and
makes bad exhaust gas.
- Volvo recommends to use commercial additives
which improve wax crystallization of diesel fuel in
cold weather if it is difficult to use Arctic diesel or
Polar diesel.
Operation with bio-diesel fuel
The heater is approved for operation with bio-diesel
up to a temperature of -8 °C (the flowability reduces
at temperatures below 0 °C).
In case of storage periods longer than 30 days it is
advisable to use FAME-free products, as ageing
effects can have a negative effect on the fuel,
especially regarding its flow properties and
filterability.
NOTE!
Blending with max.30% FAME according to
EN14214 is permitted.
