Brand new at this...new wood stove, new forum, and don't know where to start. Just want to know what that white stuff is that is hanging around the top part of stove? Looks like cotton, or insulation? Is it supposed to be there? Afraid to burn...was all excited about getting the stove in today...then when I opened the door and put in kindling...I saw what I thought was styrafoam on the top of stove...and went to pull in out, and it was ...what? insulation? Should it be there and should I just stick it back in? Brand new hybrid insert. Thanks for any info.
