Burner lab and burner assembly machine

[Colombo]

Hi all, I tried to make myself burner-lab. However, even when secondary input and fuel-inventory size are both set, there isn't any place for inputable fuel.

Similarly, assembly machine ignore the "burner" tag and proudly scream that it runs on electricity.

I've had the same problem, I don't think it can be done with the current game engine.
