I've been searching, but can't seem to find how its done. I am planning on installing a flue damper to slow excessive draft on my jotul 3cb stove. I have double wall pipe from the collar, to the ceiling straight up. Comes out the top of the stove. Do they sell a piece of double wall pipe with a damper in it? Do I just purchase the damper and try to install it in existing pipe? I was told at a local shop that it had to be done with single wall pipe only, is this true? Anyone have a good link to a site where I can purchase one and hopefully install myself? Thanks for any help.
