Thanks for your feedback. You're right on the furnace, I also noticed this. It looks like I got a bit confused while sorting there, since the item is called "chemical-boiler" by the mod itself.
I will also move the wires. I agree that they are not right in logistics (since they can't even be used for it) - I had to add most bigger mods before finally balancing the categories, especially intermediate, to see how I best split them up.
EDIT: I can confirm that the chemical furnace will be moved to production and all cables/wires to intermediate with 1.0.2!
