15.3 Fuel for Thermo 90 ST (Diesel):
The diesel fuel specified by the vehicle manufacturer
must be used. Heating oil may also be used as long as it
complies to the normal quality available on the North
American market.
We know of no negative influences due to additives.
If fuel is extracted from the vehicle's tank, follow the
additive instructions issued by the vehicle manufacturer.
If you change to low-temperature fuel, the heater must
be operated for approximately 15 minutes so that the
fuel system is filled with the new fuel.
The Thermo 90 ST heater is also licensed for use with
PME (bio-diesel), which complies with DIN EN 14214.
