About 1 1/2 weeks ago I spoke with a few members about my chimney which is 11.5 x 7.5. They said to reduce it to 6 inch. My chimney goes down about 5 flue liners and then angles over about 30 degrees and then goes straight down. Its about a 19 foot run. When I spoke with the stove dealer, he suggested installing a flexable stainless steel 5.5 inch liner so I would not have problems getting it into the chimney. I don't know if 6 inch would give me trouble. Has anyone installed a 6 inch liner when the chimney has an angle? Also, do they make adapters to go from 5.5 to 5 inch because I am looking at a Jotul, a Lange or a Cawley Lemay?

Flex liners will go through a 30 degree offset with a little effort, not bad though. To do it you will need a nose cone with a rope attached to it.
You should be able to find find the adaptors needed for the stove. The Jotuls that require a special adaptor have one included.

Well that depends sometimes it goes through sometimes it doesn't. It all depends how smooth the transitions are how sharp the offset ext. With out seeing it i cant give you any idea as to weather or not it will work. I am just curious why you want one of those stoves so much. A good example of any of them is going to cost quite a bit i would also consider some new stoves. I love my cawley and for when it was made it is very efficient but new stoves are absolutely better. Just something to think about. Those are good old stoves and i am not trying to talk you out of any of them but i think you should consider all options.
The reason I am looking for an older stove is because I'm not sure how much I will be using the stove. It's going to be in my basement and I have a fireplace insert upstairs that I pretty much heat my house with. I am looking to possibly burn 3 -4 times a week in the colder weather and depending on how much I'm working in the basement. I will try to send you pictures of the offset. Thank you for the information and I will get back to you.

There are new, efficient stoves that work perfectly fine and cost less than $1000. Englander 13NC or Madison, Pacific Energy True North, or a Drolet stove would be good, affordable options. How many sqft does your basement have? Is it insulated?

really you have never had an issue getting a liner through an offset?. I would say 1 out of 10 we do with an offset is an issue and about a quarter of those we end up having to open up the outside of the chimney?
We do it all the time, nothing over 30 degrees though. Never in the history of our business have they opened a wall for a liner to my knowledge, not in 44 years. Even offsets in the dreaded pre-fab chimney pipe.

Just don't ask his wife about all the butter that suddenly disappears.
It does take some finesse!Just don't ask his wife about all the butter that suddenly disappears.

I don't see how that is possible do you just not take jobs with bad offsets? There are just some that there is no way a liner will go through with out getting to make room. Every sweep i talk to at conventions and workshops ect has their horror stories and most involve cutting holes in walls ect. And yes it takes finess but if it is a poorly done offset it wont go no matter how much finesse you use. We also end up doing it many times in old unlined chimneys where many times they get really narrow at the attic floor.
I've seen 90 degree turns that we pass on. Typically all we ever see is 30 degrees of offset, a 6" flex liner with a nose cone and a rope will pass through it with no problems. There have been a few over the years that we had to switch to a 5.5" liner, but never cut open a wall.
I've done it in the past at another place I worked, but that was a reline as an open fireplace, I could see that being a much more common issue in this instance. With a 6" liner we just don't have that issue around here. I guess its fortunate for us that masons here always want to oversize flue liners!

That just amazes me we have at least 3 or 4 every year that for some reason we need to cut open. Some of those are not because of offsets but some are. Luckily most that are bad are for furnace chimneys so we can get away without insulation. But even bare there are times they wont go in.
