Interesting, when i called the rep at BK in Vancouver and told him about the centre cell, he sluffed it off as no big deal and said it probably moved during transit. When i told him it was straight a month before, he went silent. And it has moved more in the last 2 weeks. He never got back to me about it, or my door seal thats leaked since new. You would think these things would be built better for the price you pay! I am curious, anyone else with a BK could you have a look at your combustor sometime and just see if it has moved. Then i can have some backup info for Dennis at BK when i tell em to send me a new combustor!
I've read a report of another moving before, I think it was after almost 3 seasons of use. Moving shouldn't be hurting anything as long as all the pieces are still there with no leaks between ceramic and the frame. If I remember your stove is pretty new, the cat should have a 10 year warranty(?) so you can watch it for a while without worrying about it too much.
