I stuck my hand up in the chimney of mine and it looks like regular fiberglass insulation. the flame is not in contact with the insulation, it goes inside the chimney flue beside one of the refer pipes.. the insulation is to help keep heat in, and protect the outer surface of the chimney from radiating to much heat creating a problem with the wood that is around the deal.
check the picture on the first post.
you can see the chimney section and the refer section and the larger outer section. the insulation is around the two inner pipes more or less.. now better insulation like a high temp ceramic wool with foil backing wrapped around the pipe may help the operation but it not special insulation.
I use rock wool insulation on gas logs for the glowing embers look and that is more durable than regular fiberglass.. hech the stuff they use from factory may be rockwool. you can buy it at lowes in 40 lb bag for 40 bucks..

It seems that there is not a stand alone replacement but I can get it if I buy a cooling unit replacement !! Not a solution, since the fridge works. Was also told to use the same stuff that is in the walls in my house. Somehow, since there is a direct flame involved, that doesn't sit right with me, so I moved on from that suggestion.
In looking for a product that is temperature sensitive, I ended up on the McMaster Carr website and found the following product.
Appreciate feedback on it from those who might be familiar.
