When you're ready to bake, put the bread in, and with a Super Soaker water gun spray the stones and chain. Close the oven door quickly and you've gotten the crust you want on your bread. Stand to the side when soaking the stones. Live steam is dangerous. It might also help to have an assistant to close the door.
