Hello99: Unless they changed the rules since I recently worked as a Mashgiach, the OU says pilot lights are fine for Bishul.
And Health: We assume the reason we eat “Chodosh” is because of the Bach or one of the other Poskim, not the Rama’s “interesting’ Sfek Sfeka. I have to brush up on the rules of Sfek Sfeka (which are ridiculously complicated; see the incredibly long Shach in I believe Yoreh Deah 110), but “Is it really Chameshes Minim” and “If this is one of the Assur Minim, is this specific product Yoshon” should work.
