[Germany]) when using low sulphur fuel according to
DIN 51603.
Fuel oil additives
Fuel oil additives are substances that can be added
providing they offer the following characteristics:
■
Improvement of stability during fuel storage.
■
Improvement of the thermal stability of the fuel.
Reduction of odour development during tank filling.

Please note
Fuel oil additives can create residues and impair
the safe operation of your heating system.
The use of fuel oil additives that leave residues
is not permitted.
Combustion improvers
Combustion improvers are additives for optimising fuel
oil combustion.
Viessmann oil burners do not require combustion
improvers, as these burners operate with clean and
efficient combustion.
!
Please note
Combustion improvers can create residues and
impair the safe operation of your heating sys-
tem.
The use of combustion improvers that leave res-
idues is not permitted.
Biofuels
Biofuels are made from vegetable oil, e.g. sunflower or
rape seed oil.
!
Please note
Biofuels can lead to damage to Viessmann oil
burners.
