dens 333-F are approved for opera-
tion with low sulphur fuel oil to

tent 50 ppm).

Fuel oil additives

Fuel oil additives are materials that
can be used providing they offer the
following characteristics:
& Improvement of the storage stability
of the fuel.
& Improvement of the thermal stability
of the fuel.

during filling.

Combustion improvers

Combustion improvers are additives
for optimising fuel oil combustion.
Viessmann oil burners do not require
combustion improvers, as these bur-
ners operate with clean and efficient
combustion.

Biofuels

Bio fuels are made from vegetable oil,
e.g. sunflower or rape seed oil.
If in doubt refer to your local heating contractor.
