3.2 Applications
Danger of interference with radio reception!
The device is not intended for use in residential areas and cannot ensure
adequate protection of radio reception in such environments.
All VariFuel2/2+ air/gas mixers are designed for use with gas-powered Otto engines. The fol-
lowing substances are approved as fuels:
– Natural gas, biogas, landfill gas, sewage gas, wood gas, drilling-related gas, mine gas,
liquefied natural gas (LNG), liquefied petroleum gas (LPG)
– Additional special gases may be used upon approval (there may be restrictions in the case
of excessive moisture content or foreign materials in the gas such as tar)
Mixing the air and fuel with the VariFuel2/2+ must be done with the same pressure, therefore it
is necessary to use a balance or a zero pressure regulator within the gas train.
The VariFuel2/2+ can mix up to two gases with air. For lean gas applications (such as wood or
landfill gas) with a V-engine, it is possible to interconnect two VariFuel2/2+ to achieve the
desired mixing ratio.
If two VariFuel2/2+ gas mixers are to be used, two VariStep3 stepper motor drivers are required.
An additional splitter is not necessary.
Any use other than the one described in the assembly instructions shall be considered improper
use and will result in the voiding of all warranties.
