Hi.  I'm new to this forum.  I just replaced the rear refractory panel and baffle on my BIS 1.2 stove.  Installing the baffle last (I've done this before), I was not sure whether the beveled edge of the baffle goes toward the back (perhaps to better meet the flat top edge of the rear panel) or the front.  I decided to put it toward the back.  Not sure it would make any difference in terms of performance, but I thought I would check this forum to see if anyone has advice regarding this baffle installation question.
