Hello all,
I'm looking for help in trying to decide whether to DIY a SS liner in my boiler flue. After owning the house for 7 years, I finally opened the cleanout door on my boiler flue and found about 10 gallons of terra cotta flakes and debris at the bottom of the flue. I called a local chimney shop and they recommended a SS liner and chimney cap for about $2k. The chimney is about 30' long, 8"x8" flue with a 7" pipe from the furnace to the flue.
A couple of years ago I installed a wood stove on our other 30' chimney, complete with insulated SS flex liner for much, much less than $2k. With help from articles on this forum, I was able to complete all the work myself with a few hours of planning and a few hours of labor.
My primary concern with working on the boiler flue is that I run into something unexpected I can't handle myself. I also don't know how to attach the boiler pipe to the flex liner. Is this where a tee comes in? Do I need to use liner from the bottom of the tee to the top of the clean out? Do I need to insulate (chimney shop said I didn't, but I'm reading on this forum that I do)? I'm I going to be able to fit a 7" liner down a 8"x8" flue? The hardest part of the woodstove liner installation was bending the liner around the smoke shelf. Can I assume I have a straight run on my boiler flue?
Thanks in advance for any help or insight provided.
