What SD cards will work with my Casio EX-Z800 camera?

I recently got a Casio EX-Z800 camera for my birthday. Because it has a lot of pixels, and its pictures use plenty of storage, I want to get a good sized SD card (16G - 32G hopefully). I've also heard that SD cards come out in classes, the latest (and biggest) being class 10. My question is, which class of card will work with my camera? I don't want to have an old camera with a new card that doesn't work with it. I've looked up specs for my camera, but they fail to mention what kind of cards are compatible.
