    Hi,

    I've been running a professionally installed Explorer II for two seasons now. It was installed with fibre glass insulation wrapped around the insert (if insert is the right term here). I have to clean up white particles than fall down after every time the fire is run for an evening/day. I suspect these are from the fibre glass insultation(?) Pictures below. Any guidance appreciated.

    Not sure what the white particles are, but the fiberglass should be removed and replaced with kaowool or roxul insulation and then a block-off plate installed to seal off the damper area. At the end of this wiki posting there are links to several examples of block-off plate installations.

    It can melt when in contact with a hot pipe. Regardless of insulation you don't want the fibers drifting into your breathing space. A properly installed block-off plate will help prevent this.

    I was wondering the same thing. bigpig, if you rub the white spot with your finger does it break apart into powdery dust?

    It breaks apart into a powdery grit - and is kinda grey/white/black. There is also some accumulating on the mantle heat shield.

    How do I clean the "smoke shelf"?

    Looks and sounds like small flakes of mortar.
