I sealed around the pipe with tightly packed fiberglass insulation. I didn't know what else to use, and I know that stuff doesn't burn very good lol. Is there something better I can do there??
take a pic. so we can give some advice or idea to fix the problem. You might be able to put thimble in,also the insulation might let extra air up the chimney and effect the draft.

:idea: You could install a 6" clay thimble...add some extra sand to the mortar so it is easy to remove down the road.

Heres what I did to seal the pipe into the flue.. Stuffed fiberglass insulation tightly between the pipe and flue, I think its good. My chimney is pulling a .015 with a 100 watt light bulb in the firebox :D

For years I did the same. Fiberglass bedding the stove pipe into my thimble. My thimble was round so it was a fair amount easier to bed a round pipe in it, but I agree you are on the right track. Maybe you could fashion a tin cover over the inside for a little more piece of mind.

Hey thanks man, yeah I'm considering fashioning some kind of tin plate there :) Also, that pipe clearance to the floor joists makes me a little uneasy. I'd like to put up a heat barrier. I was told that cement board would be appropriate tacked up above the pipe, against the floor joists. Any advise there??

That will work fine, space it off the joists 1" or so.

next year or when you shut down you could always just cement a 6" thimble into the 8x8 flu
