No, nothing else needs to be done, Rak, except you may want to check that the thermometer is reading correctly. Just boil some water and use the thermometer to see what the reading is, 212 F and you are good to go, unless you are quite a bit above sea level. I was nervous about the burn in and like the others said, it's not that bad. Relax, I realize that is easier said than done but it's true. Control that temp., start early in the day, go slow and it will be fine.
