If it is very cold and the furnace has to run a lot, you are going to need those 4 6V batteries to allow the furnace to run all night !
If the point of the generator is just to charge the batteries and you are going to use your existing converter/charger then a 2000W (peak) is adequate. Buying a larger generator, especially one that has an outlet compatible with your plug,
is a good idea.
If your batteries get run down a long way, it will take several hours of charging with the generator running.
Do NOT use the 12V output of the generator. It is not meant for battery charging.
