My OWB is in my barn. The stack comes up 6ft, turns 80-85 degrees and exits the bldg with a 6ft 6" stove pipe.

Does the stack have to end in a vertical orientation or will this work?

Sounds like a creosote issue eventually.

[Scott7m]

Is it insulated chimney or regular?! 

If its insulated you should be fine, burn a batch of cardboard once a month or so and let her eat!!!  It will clean it out well

[slimjim]

Let me get this right, you have 6 feet of horizontal pipe sticking out the side of your barn with no vertical stack up the side to above the roof line by 3 feet and you are using a conventional boiler, have you ever seen the sparks and flame that come out of the stacks of a conventional unit. Never mind the smoke and creosote what about the FIRE HAZARD, are you nuts ?

[uncle]

I've never seen the sparks and flames of an OWB, that's why I come here.
My roof is corrigated and I was leary about going through the roof so I went out the top of the wall. It is not above the roof peak. It comes out in my pig pen.
The pipe is single walled.
I can turn it up and extend it above the peak easy enough, I just didn't want to add another 90.

The pigs will probably be unhappy once a month.
What brand stove are you running?
It sounded like the pipe was reduced to 6"?

Garn stoves do this but its fairly low to the ground, very efficient & requires a 55 gallon drum to catch anything.

Brian, please listen, the stack temps on a conventional wood boiler can go as high as 1200 degrees and wood can combust as low as 600 degrees, there is a reason why outdoor boilers are called outdoor wood boilers, if you feel you need to have the boiler in the barn then there are some precautions you should take. First keep all combustables at least 3 feet from the boiler on all sides, floor and roof, single wall pipe will burn out or rustout in 2 years, use stainless insulated pipe only and keep it clean, bring the top of the pipe at least 3 feet above the roof line and really should be 3 feet above the peak. If you use the unit the way you have it now you are begging for a fire that may cost your family thier lives, get a pro to look at your install

I'll agree it's not something I'd wanna do with single wall pipe..   I don't trust it to well

I've seen a lot of folks put them in old barns and such though

With a single wall you have a higher fire risk and are def gonna have creosote issues

I'm running the Earth Worrd MountainMan furnace.

I do not have too much invested in the stove pipe and I can easily re-do this.

I guess the best would really be to run it through the corrigated roof and be done with it. Going through the walls I really did not have to worry about sealing it water tight.

Thanks,

Just buy some good double insulated chimney and be able to sleep at night.

Brian,

I have my stove installed in my shop and have single wall stainless.
They use triple wall 3' before and 2' after the roof though.

I know several people with this setup and no issues.

I would just be leery of the wall penetration and catching anything else on fire.

[bruey]

I don't understand why u would want it in the barn anyway?

[uncle]

Its out of the weather, my wood is dry in there, I have access straight to it with my truck and its 1/2 way between the house and the shop so that my runs were not too long.

Mine is 10 feet from my shed, 3 logs in my wheelbarrow , 1 minute later, done. Don't have to worry about pipe or fire.

[willieG]

mine is in a shed...8 inch schedule 40 pipe wrapped in 1200 degree industrial insulation and clad with aluminum sheeting for a chimney....0 degrees and 25 mph wind at 6am and leaving for work...shed is out of the wind, no snow or freezing ice pellets blowing down the crack of my butt and can look over the stove and check things out with the lights on. fill it up and head for work knowing things are working as they should. OWB in a shed?  i think its a great idea
