My BIS Ultima, after 8 years of hard use, has a big hole in one of the air tubes. How do I install a new tube? The old tube just slides back and forth and the ends disappear into the metal on the sides of the fireplace. There is no socket on the sides that I can remove it from. I suppose I can get it out in two pieces after it totally disintegrates but how can I install the new one in one piece?

According to the manual I found on line, there is a bracket for securing the secondary air tubes, but there is no picture of it.
I'd look for something that comes off one end of the air tubes, maybe both ends...

I found out today when I replaced the tubes. There is a flat bracket on the right side of the fireplace held in place with two square drive screws. The bracket has tabs that go into the holes on the right end of the air tubes. If you remove both screws and remove the bracket, the tube will slide out. The inner screw is frozen in place so I couldn't loosen it or remove the bracket. I used a cutoff wheel to cut the old tubes near the right side. The short piece remaining could be twisted enough to get it off the tab. I then removed the front screw and pivoted the end of the bracket upward. I couldn't get it up enough to insert the new tube because the far end of it hit the tube in the back. I then used a cutoff wheel to cut a slot from the end of the new tube to the hole. The slot was wide enough to slide over the tab. Then I rotated be bracket back down and reinstalled the retaining screw.
Did you need to take out any or all of the refractory panels. It looks like the flat bracket is behind the RHS panel. Not sure if I need to take out all the refractory panels to get at the bracket. Appreciate your input.
