Riello burners with bio-fuel

Does anyone have any experience or information regarding 40 series burners using bio-fuel, up to and including B-20.
We are going to be changing an NX burner on an W/M ultra oil.
We prefer the Riello but became a little unsure due to the fact that the customer is using B-20 bio-fuel.
We would then opt for the Carlin if the Riello is not recommended. As we have the option of installing a bio-fuel pump.

    I think the NX is better, but possibly a little finicky if you down use the right nozzle and set it up correctly.
    All the guidelines are the same. Get bio gasket for fuel filter get bio gasket for pump cover...
    Recommend double filtration close to the INSIDE (hopfully) tank (A25, then spin-on) because bio will clean your tank and send it to the filter(s)
    May have to goose the pump pressure up a little, and of course do full/proper set up--true zero smoke, combustion test.
