Hi, I have a question for everyone. I never realized u could change the program on this stove so when I checked my stove was on "A". I have read that most PDV stoves are on "c". Is this year dependent? I called englander before and my lower three settings are supposed to be 6 9 1 where newer pdv stoves are at 6 4 1. So should my program be "c"? I am asking because I bouth this stove used and the previous owner fiddled with everything on this stove.
