We moved into a house that has a pre-existing double walled chimmney that was added through the wall and outside the house. They used 7" Metelbestos chimney/flute.

I know the Enlgander needs a 6" stove pipe, so I have found online some adaptors that go from 6" to 7".

Does anyone know if having the 7" chimney for most of the exhaust and use the adaptor for 6" be an issue with airflow? I have heard that if the chimney is too wide for the stove it can cause issues. I really do not want to have to replace all the 7" chimney to make it a 6".

Thanks for any help!
 
Try it it might work fine how tall is the chimney?
 
I would call ESW and give them the specs on your chimney, height etc. and see what they think. Personally coming off the stove with six inch and into seven inch with a tall enough pipe shouldn't be a problem in my opinion. As I recall you are putting it in the basement so you will probably have a chimney outside in the 18-20 foot range.
 
Yes in the basement of a 2 floor house. That is a great idea to just call them up. I don't think the 1" should be a huge deal. Better than 8" to 6".
 
It's fine. You can go bigger (to an extent) but not smaller than the collar.
 
With a basement install on a 2 story house you should probably be fine

Not true Many manufacturers say its ok to go down to 5.5" when over a specified height and oversizing can have a huge effect on draft
 
I have my 30 venting into an 8" chimney without and problem. about 4' of 6" DBL wall into 12' of triple wall 8" - a;; Duravent

I know you're trying to be helpful but this thread is specific to the Englander and if we assume the modern and common NC30 then,

http://www.englanderstoves.com/manuals/30-NC.pdf
States on page 5 "the connector pipe should be 6" and never less in diameter than the collar on the stove."
 
Further it states,

"if the area of the flue is greater than the collar, it should never be more than 2.5 times greater."
 
Sometimes rules get broken. IIRC we have a mod with a 30NC on 5.5". If I had 30ft of chimney to line I probably would do the same.
 
The velocity in a 21' 5.5" liner is like a Hoover. The draft in the 5.5" 32' liner in the basement is gonna suck a split into the baffle one of these days.

Me too. The thread is about a guy with a 7" flue and we all seem to agree that it is acceptable with an NC30.
