Through the wall stove pipe, any ideals?

[dugger10]

I nearing completetion of a 30X40 metal building for my home shop. I have been planning a wood burning stove and pricing stove pipe and through the wall fittings to protect the sheet meatal and insulation. I was very suprised at the cost, $109 at Tractor supply. Not that Im extremely cheap, just soon to have three in college, but was wondering if anyone had other ideals or expereince building an alternative to the Tractor supply expensive pipe. The stove pipe is cheap, just the through the wall piece is high. Any ideals would be great, and this is my first post on this board, I did search first. Great site and thanks

Most through the wall fittings assume frame construction and have a lot of clearance built into them to keep any nearby wood cool.
And they are expensive because the mfgs have to pay the designers, the testers, and the labiality insurance.

If your walls are all metal you may be able to cheapen it up with something homemade.

But your insurance co. wouldn’t honor any claims.

Care to explain how he will catch a metal wall on fire?

The pipe is more expensive because it is stainless probably? Exhaust heatng and cooling accelerates corrosion. If you don't want to do it over do it right. Insurance company still has to pay up even if you do something stupid, unless they can prove you tried to burn it down. You may have to sue them though.
Thanx Trevor

i have seen masonry collars that will give the insulation/isolation your pipe will need, but that is truly more work. the transition pieces wall/roof will be more expensive but they are probably your best solution. you may try to find a supplier in your area, not a neato little gas log/fireplace dealer, as the prices will likely be higher. i have bought several pieces for my woodstoves, yes i have several in use , from a web site/store out of MI. i will try and remember the name. but do a search and you will be better off than the TSC stuff. johnny

Thanks guys, I'll do some looking, just seemed like 109 bucks was a little high. Don't want any issues, I would rather spend the money thanhave problems.

Take it from experience.....if you go through the wall make sure that the pipe extends above the roof line. It will not draw properly and the gas company will come and check to make sure you do not have a major leak. it was causing an incomplete burn forceing air back into the burn chamber. Glad i have a cousin in the heat and air business, just wish he would have came around sooner.
* this is on a natural gas heater btw.

Ignore the "The Sky is Falling" folk. Yes, you can do it. You take responsibility for it.

When I told local stove places I wanted to run thru my wall w single wall pipe, they ran screaming. Telling them it was a shop (not a residence) and a METAL building was no help.

This is NOT rocket science. I'm running 6" stove pipe so I got pipe that's 10" ID. So yeah, I've got 2" air space per side. I built flanges to bolt in my wall. I capped the inside around the stove pipe. On the outside I did expanded steel on the bottom half to allow heat to escape quickly, but kept it solid up top to mitigate rain entry.

I've been using it for 3+ years w plenty of raging fires. I can lay my hand on it when the stove is going (it's about 7' above the stove), and oddly......my shop hasn't burned to the ground yet.

With all the hot work I do in my shop, a wood stove is low on the list of concerns.

buy the stainless kit...

The way IGN did it is way over kill.
But it is still homemade.
It goes beyond a safty thing.
It becomes a insurance thing.
If your shop isnt insured anyway (and many are not) then go for it.

you have 2 options
1 spend the money, you can make more money

2 look at how the manufactured one is done, get some metal and copy their design.
that is if you know how to make stuff out of metal

I have made them before for exhaust stacks on boats, not hard to do. I am not really sure how to explain it though, the ones i have made were mounted vertically so it would be a bit different.

I bought a 2 foot length of 8 in stove pipe and a cover cap for it. I cut a 6 in hole in the cover cap and ran my 6 in stove pipe through it. I cut an 8 in hole in the steel outside wall and used High temp automotive silicone to seal the 8 in pipe to the steel outside wall and to the drywall inside wall. I stuffed the 1 in space with fiberglass. Works fine!
