I have an 18' masonry flue with clay liners. I am installing a 5.5" flexible stainless liner from Chimney Liner Depot. The flue is an old oil furnace flue and is kind of weird. The bottom has 2 openings - one had a plug and the other is where the pipe came through to the furnace. I have opened it up a bit to insert the stainless clean out tee. I have 3 bags of National Chimney pourable liner insulation mix for insulation.
I will try to attach a couple pics of it in place (the piece of wood is just to hold it for pic!).
Here's my question: should I screw the tee cover in place, fab block off plates for both openings, and fill this whole space with insulation? (would disconnect stove pipe for clean out), or:
Should I block it off right above the tee and leave these openings for clean out access?
Thanks in advance for any advice!
