Everything is "odd" here in Newfoundland!
lol.
We just came out here to the wilderness 1.5 yrs ago.

Thanks so much. I'll look into the Morgan Superwool 5-minute riser.

Hi!  This is my second post, and I am new to "forums" in general.  
Thank you all so much for sharing here.  We are learning so much as we plan our RMH build.

Question:  We have an existing 7 inch chimney. New last year.

Has anyone got the J tube dimensions to accommodate the CSA of a 7 inch stove pipe?

I realize I can calculate it with pie r squared etc.  (Explained here by Richard Freudenberger- Living Web Farms: https://youtu.be/MNKgkgukmkc?si=LV_dbc3JOM3JbGzz
but I thought there might be a chart which doesn't jump from 6 inch to 8 inch.  

TIA.

Edit : I've determined 6.25 inch square equals 39 and that's close enough to the CSA of a 7 inch @ 38.465 sq in.  Correct?  

So now, the upright dimension can be anything as long as it stays within the 1:2:4 guidelines.  Or is it 1:1.5:3.5?  

Thanks again.

Hi Rex.
I am new to this forum.  Thank you for this contribution.  I am in the research stage and planning a RMH build this spring. The "tee" exhaust to the previously existing chimney and woodstove has me intrigued. I would like to maintain my existing wood stove for now, do the build of the RMH, and later switch the old woodstove to a cookstove - maybe a Walker.  

How is it going so far?  Is your RMH exhaust working out?  Have you fired up the Blaze King, and if so, have you had any complications with the exhaust/chimney combined?

Thanks again, in advance.
