[Avodah] waiting 24 hours before libun

Obviously as per the Aruch haShulchan YD 121 #22 [b'libun ein chiluk 
bein she'hu
ben yomo o eino ben yomo ..,. d'ha'esh m'chaleh ha'kol'] you don't 
have to wait 24
for libun GAMUR. However, I was referring to libun KAL (oven). The problem is
whether we pasken chametz before Pessach is hetera bal'a or issura bal'a.

The entire "oylam" requires a waiting period of 24 hours (after 
cleaning) for Libun Kal.
