I have a 400sf room with 12' cathedral ceiling.Why can't I just run black stove pipe straight up out of my stove,thru ceiling,and thru roof?I would use shielding thru roof and ceiling,and terminate pipe 3' higher than roof peak.

You'd have to switch to double/triple wall through ceiling/ roof-w/ shield/ collar & up. They make it to take the 6" black.

It just seems too easy...Straight up and out.no elbows,a warm stack,more radiant heat.The perfect chimney can be very inexpensive.It might not be permanent,but easy maintenance.Lucky to have these conditions for my new/old stove.

Straight up and out always performs the best. Black pipe won't last more than a season in the outside elements though. Black pipe to the ceiling and stainless from there is the best compromise if you want it to last a long time.

I am using 7" pipe,a little harder to find,but I can get it.I was also wondering about how copper pipe would last.I could see making some out of a sheet,if it can't be bought.

I would think the acidic content of fly ash would chew through copper rapidly. You could wrap the base metal stove pipe with thin copper sheet as an alternative.

I prefer Robs idea... heaviest, best deal, black pipe you can get... strait shot up... then transition to the stainless 2/3 wall... its the best answer and the lowest cost (how often can you get your cake & eat it too!) .... cap it, to baro or not to baro... this is the next question... Dougie is outa here!

That's exactly how mine is, 13 feet of stove pipe (Lot's of heat radiating from that ) and 8 feet of triple wall. Do use bracing, I made it from 1/2 inch EMT and fabed my own collar, on the triple wall. I do have an MPD but no Baro, I keep debating on that, but so far have had no real need. I run the MPD damped down completely almost all the time and the stove just idles alongfifthg wrote:Straight up and out.no elbows,a warm stack,more radiant heat.The perfect chimney

I found 6 and 8inch ceiling thru roof kits for the chimney.No 7" found.What do you think of just going with 8" stainless kit,and then slipping my 7" black pipe right up thru that to top?

Can you find an adapter 7" to 8" coming off the stove & just run all 8"--or a reducer going to 6' & going all 6".

There are adapters,I thought it best to stay 7",if that is what it was designed for.I figured getting an 8" kit and slipping my 7" pipe in it would be easy and low maintenance.

If it behaves anything like mine, I doubt you would have any problem with draft even with the six inch. The only time I notice it being sluggish is a cold start on a rainy 50* day, nothing a couple pieces of newspaper won't fix. Start up or tending is the only time it's wide open any other time it's damped down.

with such an efficient,straight up and out set-up,I guess I could be talked into reducing to 6" pipe.There are economic advantages with that.Looking likely...
