I have an old woodstove I want to replace with this gravity fed gw1949, off the woodstove now is a 6” single wall pipe, the gw1949 says use a 3-6 adapter, I was looking at 3pvp-x6 but it says double wall will this work or could someone recommend something? also have a question about the existing pipe just below the seam it has a ring crimp looking thing is it just slipped on or is there a sealer or something in there also?
Thanks
