• Mixtures with used oil are not allowed!
• After refuelling with winter or cold diesel or the
listed blends, the fuel pipes and the dosing pump
must be filled with the new fuel by letting the heater
run for 15 mins.!
Please note!
Fuel supply
Fuel quality
The heater can easily run on the commercially
available fuel you use for your engine.
Fuel for special cases
In special cases (above 0 °C), the heater can also run
on fuel oil EL or parafin.
Fuel for low temperatures
Refineries and fuel service stations automatically
adjust the fuel to normal winter temperatures (winter
diesel).
This means that difficulties are only to be expected for
extreme drops in temperature, as also apply to the
vehicle engine.
Please also refer to the vehicle manual.
If the heater is run from a separate tank, please
comply with the following rules:
For temperatures above 0 °C, any kind of diesel fuel
as per DIN EN 590 can be used.
If no special diesel fuel is available for low
temperatures, then paraffin or petrol should be mixed
with the fuel according to the following table:

Operation with bio diesel (PME)
The heater D 3 L C is certified for operation with bio
diesel as per DIN V 51606 in flowing state.
• The fluidity of bio diesel decreases at temperatures
below 0 °C.
• When using 100 % bio diesel, the heater should be
operated twice a year with diesel fuel (in the middle
and at the end of a heating period) to burn off any
possible PME deposits. To do so, let the vehicle
tank run almost empty and fill with diesel fuel
without adding any bio diesel.
While running on this tank filling, switch the heater
on 2 to 3 times for 30 minutes at a time at the
highest temperature setting.
• When operating with diesel / bio diesel mixtures of
up to 50 % bio diesel, intermediate operation with
pure diesel fuel is not necessary.
