If the blech falls off

Hi,

If a blech (see previous posts for a definition) falls off the burner, one may put it back in place, if:

1. It is not entirely off, and
2. Putting it back in place would not cause any part of the metal to be heated to the point of glowing.

(Rav Moshe Feinstein, Igrot Moshe Orach Chaim 4:74:Bishul 29-30)
