Platform for chimney support

[Vermont2014]

Good morning all,

Finally getting around to installing a wood burning stove in my 24 ft yurt in NE Vermont. I live 7 hours away and don't get up there but a couple of days per month.

By the time I get the stove installed the ground will be frozen and I will not be able to pour a concrete support pad for the chimney.

Would it be possible to pour the pad and install the supports without knowing for sure what size and brand of stove will be installed?

Thanks in advance for any advice.

I don't see why not. I tend to over build but your chimney support isn't really associated with your stove. I have a Jotul Black Bear stove, which has a five inch to six inch adapter that comes out of the stove. I have six inch pipe that makes the curve and then a six inch to eight inch adapter that allows me to go out the yurt wall with a double wall stainless steel pipe, then on to my outside chimney which is also eight inches. You only need to support the pipe weight. Your biggest concern should be clearance behind the stove and protection as the pipe goes out the wall. Easy peazy! Good luck!

Thanks for the response.

Once the stovepipe leaves the yurt is there a recommended horizontal distance before the pipe goes vertical? I figure that I want to pour the concrete pad so that it is centered under the vertical section of the stovepipe.

Just to be clear I plan to have the stove pipe exit through the side wall of the yurt.

There might be something in the codes. I would guess keep to the flammable clearances stated by the chimney maker (something like 2-8 inches for double wall).

Thanks for the information.

This forum is a great source of information for yurt neophytes like me!

I would check your local code. Ours had something where the chimney had to clear the highest point of the roof by I believe it was 24". Once you have that figured out, you can set your mast and figure out how much cement you will need by the weight of your insulated pipe. See my chimney post for perhaps some inspiration.

Thanks for all of the advice.

Jafo your post was really helpful. By the way, the Woodstock Soapstone website has some good info on the subject in case no one mentioned it before.

It so happens that I pass right by Woodstock Soapstone on the way to the yurt. Think I will take a tour!

They make a pretty awesome wood stove, just bring a good back with you when you move it lol.

Hi all,

Finally got the 2" galvanized pipe that will serve as the chimney support into the ground. I was able to dig down 3 feet, which is pretty good in this part of Vermont.

Since I am working alone and can't handle a 20' pipe I will be using 2 10' sections of threaded 2" pipe joined by a coupler.

Does anyone see an issue with using sections? The 10' section is in the ground with 7 80lb bags of concrete and seems solid as a rock.

Thanks for any comments that you can provide. Photo attached of the installed pipe.
