Wood Burner Installation

[Yamaha74]

I have a wood burner that I would like to get installed before the winter. The wood burner currently has about 4 feet of 8" black pipe coming out of the top of it. I would like to go up as close as I can to the ceiling and then take it out the back wall then up about the peak of my barn.

I am totally clueless on what is acceptable as far as what type of pipe to use inside and outside and through the wall. Can anybody give me some suggestions?

I would use stove pipe inside and switch to SS pipe on the outside. I think it would last longer and you wouldnt need that much. With a SS cap. I dont think a straight wood stove needs double wall pipe but you may want to check the local building codes. If its not done to code and you have a fire your insurance might not pay.

First off, you are going to get blasted for bypassing "code" on a woodburner in a garage or barn situation. Nobody has ever done that until now. Now that is out of the road....do you have a ceiling in the area or is it an open area to the roof? If you have a ceiling, you will need to get a flue kit that has the stainless steel pipe, the transition box for the ceiling, and the proper flashing for the roof. If you are open clear to the roof, is it a metal roof? You will need stainless double wall pipe and the proper flashing. You can run heavy black single wall made for woodburners up to the double wall. DO NOT VENT THROUGH GALVANIZED pipe that is not made for woodburners. Any of the box stores can hook you up with the proper items you need, or if you have a woodburner store near you, best bet is to check it out for the proper hookup. Also when the flue is hooked up, make sure the female end of the pipe is up and the male end drops down into the top of it. By doing that, any creosote that would happen to buildup and run down, will run down into the preceding lower pipe and not run out through any gaps. Smoke will be drawn out through the pipe properly. A woodburner flue is opposite of the way a car exhaust is hooked up.

Do a good internet search on this one.
There is a ton of stuff you have to learn to do it right.
And if you are starting out “clueless” you should do a lot of research.
It is sure to teach you things you would have never thought of.

I didn't want to go up through the ceiling. I wanted to go out the back wall and then up.

Use an approved double or triple exterior pipe for the outdoor portion, and put a tee on the bottom (cleanout) where it will penetrate the wall. The wall penetration should be done with a system designed for wall penetrations. Inside you can transition to heavy black pipe once you are far enough away from combustibles. Try to have the horizontal through wall pipe running up hill to the outside.
You will need to clean the chimney periodically. Keep that in mind when installing it, because you might have to take it apart to clean it.

I know it is $, but I would go triple wall all the way up and straight out. Easier to leep clean, safer, etc. We burn lots of wood all winter and have for over 25 years. I wouldn't do it any other way, but that is just my humble opinion.

You can use black stove pipe inside. You need to maintain at least least 18" clearance between the pipe and combustibles. You will need a special wall thimble to transition from interior to exterior. On the outside you will need to use insulated pipe. You will need a support bracket at the thimble connection. I'd put a T with cleanout first and then continue with pipe up the wall. I think if you go to the simpson duravent site you can see the various parts and can read through instructions on various installation options. I ran my wood stove straight up through the roof. Gives the best draught and is easy to clean. I added a pellet stove last year and ran that through the wall.
