I am finally installing my Harman XXV. All the venting is complete and all is left is preparing the stove. The manual for Harman XXV is poorly written. It mentions that I should connect the provided "grey" (its more like black - not grey) 60" sensor. However it does not tell you which slot gets the red wire and which slot gets the black wire. So before guessing and totally screwing this up ... can some one please clue me in as to which way the connection works. if I am standing behind the stove and looking at the two little slots, which one (lef/right) is to recieve the red wire? Thank you so much.
