Hey guys,
After several days of cursing and unbridled violence in an enclosed area, I've successfully removed my old Heatilator Mark 123 to make way for a new insert. I lucked out an found a brand new Lopi Freedom for $1,000. My question is what to do with the existing stove pipe.
It's around 8.5" ID and 14.5" OD and approximately 22'8".
After doing some reading, I was pretty convinced the 6" stainless steel flex liner was the way to go, so I ordered 25' of Forever Vent double ply. Then after some more reading and finding numerous "double ply is crap" comments, I canceled the order.
The piping is mostly a straight shot expect for two 45s near the base. I have access to an HVAC discount so would I maybe be better off dropping down some ridged or going with a single ply flex and wrap it in insulation?
Any help or suggestions would be highly appreciated. I have a mason coming to set the stove in January and would like to make sure I have the chimney ready for him beforehand.
Sorry if the photos aren't clear, it's very cold here so I had to shove a bunch of stuff up the pipe to stop the downdraft.
