    Our F500 vermiculite baffle developed a crack down the center, front to back last winter and I finally got around to ordering a new one. When we picked up the replacement I mentioned to the dealer my concerns with the mineral wool blanket. In case I should booger up the old blanket and cannot reuse it, how long would it take to get a new one?

    He told me that it is not critical to try to reuse the old one and that it is there for Jotuls efficiency qualification. If it was not reinstalled, efficiency is minimally impacted and I could expect better draft.
    He made it sound like it is just a moot detail in the stove's function and it is really not needed.

    They can easily aquire one for me, so availability is not an issue...but should I even bother with trying to reuse the old one?

    If the manufacturer got a better efficiency rating with it in place due to a hotter fire below, why wouldn't one want to continue getting the maximum efficiency benefit? Perhaps you could perhaps upgrade the vermiculite board to one you custom cut with a higher insulation rating if you are finding the blanket to be a bother.

    I would also recommend replacing it with the manufacturers replacement board. The stoves was designed to burn efficiently and cleanly with it so it should be used.

    I was just dumbfounded by the dealer's comment. I have a habit of always having a back up plan just in case the worms get free, this is why I checked the availability if I do something dumb...it seems like a fragile material. I can't imagine I am going to ruin it, and plan on reusing it...if not I will aquire another.

    I just wanted to share this tidbit in case anyone has heard the same.
