Pink insulation in chimney

[derbydude]

I pulled out my pellet insert to clean the flue and noticed pink insulation hanging out loose around the edge of the opening (where stove connects to chimney).
Either I hadnt looked or it wasnt there last year. (I did pay to get furnace flue cleaned, so wondering if their vacuum dislodged this).
Anyway, wondering will this be a fire hazard?

Roxul or other mineral wool insulation is what is wanted there as their temperature tolerance is greater than the pink insulation. Roxul withstands temp to 2150F vs. the pink stuff that starts to break down around 1000F. Get the pink out of there! You might want to check the top cap for the same type of insulation if it is not too tough to get to.
