My first time is going to be an All Nighter!

[Smoke Stack]

Good evening, and happy holidays to all. I've been soaking up information from this site over the past few weeks. I express my unconditional gratitude to those that share their life experiences with the profound chemistry of all that is involved with burning wood.

I recently purchased a commercial property for a measly $10,000.

I recently received an All Nighter, Mid Moe, for nothing. (Great shape, too)

I have the O.K. from my local building inspector to install.

I got wood!

Stove is installed!

I have two interior elbows with about 6' of pipe (single wall). I then go through a block wall (horizontally) with a 3' piece of class A double wall insulated, to a clean out tee, then up 6'. This set up gets me 3' past the roof (flat roof).

It seems that I have sufficient draft. When holding a lighter in the stove, the flame wants to flow up the flue. I burnt a tiny bit of cardboard and the smoke went right up the flue. I have about 15' of chimney with 3 elbows, so therefore, I have no chimney, according to some.

I'm going to give it a first test tomorrow. My more experienced wood burning buddies couldn't believe it when we did the draft tests. There really is some serious air flow out the pipe. How does this "seem to work" and what can I expect if I'm wrong? Believe me, I don't mind being wrong. In fact, I thought I needed more chimney to begin with. I'll hold out until after the first run. If I have to add more chimney it will require extra support.

Thanks, All!
Happy Thanksgiving!

If you have a strong draft, go for it. Just keep and eye on the bends later. If your draft starts to fall off check them first. Is it possible to turn the two inside bends into 45's. That would make the run a bit smoother and less likely to plug up.

Hello there, Owl. Thanks for the reply. I started the stove around 10am and it has been going strong ever since. Putting out some great heat, too. Unfortunately I cannot use 2 45's on the inside. I utilized a hole that was already in the back wall for a paint booth vent. I just blocked in around the 3' section of class A going through the wall.

I'll keep an eye on the elbows. Hot spot for creosote build up? Luckily, this set up is going to be real easy to clean. I can stand on the roof and swab down the chimney with ease.

Do you have a fairly drafty building? and outside do you have a fairly consistent prevailing wind? I'd say those may be 2 things that will help draw a consistent draft.
If things fall off over time you may want to consider the extension on the last upright section.
Are you at a significant elevation?

Yes the building is fairly drafty. I suspect the stove draws a lot of cold air from the main building, which is 50'x50'. I installed the stove in the back addition to the main building, which is 20'x25'. I live in a little bit of a valley with two decent hills to the East and West. I think the draft has something to do with the wind blowing across the roof of the main building. The back addition is 2' lower than the main building, so the top of my chimney is a little higher than the main roof.

I ran the stove for three days with absolutely no problems. I spent a lot of time playing with all the adjustments (air intake, damper) and using a couple of fans. I'm definitely going to install a ceiling fan because there is a lot of heat getting trapped up there.

Question: Will the extra section of class A pipe add anything extra to the efficiency of the stove, burn or heating? I'm under the impression that the extra length would be just to get a better draft.

I agree with you and with a draft you have now, and it's fairly consistent, I'd leave it alone.
