Level 7 - How do you cook the sausage?

I know I should be able to figure this out, but I can't seem to figure out how to cook the sausage. Where do the candles go? Under the big tank? I can connect the pipe, but I can't seem to get the contraption moving.

I figured out my own answer after fiddling around with it some more. You have to put one candle underneath the sausage, and the other goes as close to the big tank as you can. Then when you start the machine, the water will heat up and rotate the sausage. After a little bit, the candle will cook the sausage (although not the way I would want to cook a sausage).
