I have a question for you pros on here. We just installed our hearth and put the stove on it. Problem is where the chimney comes through the ceiling, does not line up with stovepipe coming from the stove. I cannot move the stove foward or back because then the clearance limits are not up to code. I see that for stove pipes they make a 45 and a 90 degree elbow but that is way to much it looks like all that I need is 15 at the most. Does anyone make a 15 degree elbow for stove pipe? Or an adjustable one? Also what about any kind of flexible stove pipe? I know they make flexible liners. Thanks for any help and ideas we are so close to a test burn.

If the stove pipe is just single wall black stuff, I believe they make an adjustable elbow for them. Or you can use the same adjustable elbow at the stove outlet as an adapter and adjust at that spot for your offset.
 
So two 45 elbows back to back would offset it too much? I think thats only like a 6" offset if even.

Just checked the simpson catalog, with the DVL (double wall) two 45's back to back is only a 4.5" offset. The single wall is 5.5" offset.

What is the pipe diameter, 6"? What is the offset from the centerline of the ceiling pipe to the centerline of the stove flue connection?
 
Thanks guys. It is an 8 inch stovepipe and to clarify I can go back with the stove just not foward. I didn't even think about 2 45's back to back I think that might just work I will have to try that today. I appreciate all the help.
 
I think if it is only 24ga single wall stove pipe you can buy an adjustable elbow. It is made up of 5 sections that allow it to swivel. So you could actually make it into a straight pipe or anywhere up to a 90 degree angle. Remember though the clearage to combustibles for single stove pipe is 18" so you may have to apply some sort of pipe shield.
 
This is 6" pipe, but you get the idea. I used two 45's, but you could also use two 30's if two 45's moves you too much, or even two 15's. Rick

So--it's okay to use an adjustable elbow for wood stove? I have pretty much the same question--flue hole in chimney is about 3 inches off--but an adjustable elbow would definitely allow it to work--was told the elbow had to enter at perfect right angles--is that so?To what fegree can it be at a slope?

many thanks

It's OK to use so long as it's made to use for stovepipe. The entire flue from the stove to daylight should ideally trend upward. A short horizontal run probably isn't a showstopper, but you never want to angle it down at all. Rick

I just installed my new stove and used 2 adjustable elbows. I needed the stove out a bit further than the masonry chimney because I put a blower kit on it (the blower kit was larger than I expect it to be). Although I've only had 2 of my 3 break-in fires, there's no smoke and the draft on the stove is very good. You should be able to get adjustable elbows at most stores that carry stove pipe. Good luck on your install.
