111jag Posted November 30, 2007 Report Share Posted November 30, 2007 Hi, I have a 6" x 9" chimney flue (inside diametre) and was wondering what size of stainless steel flexible chimney liner can be installed? Will a 6" chimney liner fit? Is it a do-it-yourself kinda job? Can I run the line straight to the stove from the top of the chimney or do I need to install a tee with a clean out cap? If you have done this before, can you guide me through it. Thanks in advance, Quote Link to comment Share on other sites More sharing options...

Les Posted November 30, 2007 Report Share Posted November 30, 2007 Rob, What kind of fuel? I have inspected hundreds of liner installations and installed just one myself. I would not do it again unless it was a clean clear shot from top to bottom. Quote Link to comment Share on other sites More sharing options...
111jag Posted November 30, 2007 Author Report Share Posted November 30, 2007 It will be a wood burning stove and it looks pretty clear from top to bottom. The only problem is at the bottom it hooks a little bit to the front and the front of the old fireplace is all bricked in except for a cleanout at the bottom. I've vacuumed everything, so it is pretty clean. The question I have is will a 6" fit, or should I use a 5"? Does the 5" meet code standards for wood burning stoves?

Will a 6" chimney liner fit? Where you're at, you'll want a double-wall insulated flue liner. Check out Simpson DuraVent. The should have it in oval. Is it a do-it-yourself kinda job? ,I've inspected thousands. I've installed 2 on my own homes and they haven't burned down - yet. Follow the manufacturer's instructions and have your work inspected. Can I run the line straight to the stove from the top of the chimney or do I need to install a tee with a clean out cap?Top-venting stoves typically don't use a "T". Rear venting usually do. Check the stove manufacturers instructions. If you have done this before, can you guide me through it.Check the stove manufacturers specs for flue size, follow the flue liner manufacturer's installation instructions and then have your work inspected. Does the 5" meet code standards for wood burning stoves?That will be specified by the stove manufacturer. Quote Link to comment Share on other sites More sharing options...
Hearthman Posted December 2, 2007 Report Share Posted December 2, 2007 Call in a specialist. You're waaay over your head here. First of all, the liner must be insulated to meet UL1777. You cannot install a 6" round into that flue and insulate it unless you eithe bust out the flue tile or use an ovalized liner, but the oval won't fit in the dimensions either in this case. No, you cannot downsize the liner. If you are asking these questions, then there's bound to be a lot more about the stove siting, floor and wall protection, stove pipe connections, etc. Do yourself a favor and hire a chimney contractor, preferrably a Certified Fireplace Inspector. Check at www.f-i-r-e-service.com You can also check for an NFI Wood Burning Specialist at www.nficertified.org Call your insurance company before you do this. Otherwise, they could cancel your insurance. HTH, Hearthman Quote Link to comment Share on other sites More sharing options...
kurt Posted December 2, 2007 Report Share Posted December 2, 2007 The preceding 2 posts are good advice. This is not a DIY forum. The question is honest, and I respect it, but this is one of those things where if one has to ask, it's imprudent to imagine they can also know all the other variables that comprise a safe installation.

Eric B Posted December 2, 2007 Report Share Posted December 2, 2007 I think that if you really get down to the details you may find that the stove manufacturer will specify the exact liner, not just the size. Stoves are tested with and approved for use with specific liners. I know of cases where a liner needed repair/replacement and the specified liner was no longer available which resulted in the stove/firebox having to he replaces as well. Now an unspecified liner may work fine but you would be outside of the approved/tested perimeters and I would not want to give anyone the impression that it was ok and safe.
