class a double wall insulated pipe temps

Hey guys I'm trying to put a barrel kit stove in my garage. I got 4sections of 8 inch pipe that will take me most of the way out, and 6inch up to that. I'm going through my ceiling that is osb and was wondering if any of you have a similar situation and knew what the pipe temps on the outside of the double wall insulated got to be. My 6 inch on my boiler and when it's running the pipe is as cold as it is outside. Also if anyone knows any other regulations on it it would be a great help! Thanks!

 

usually 2" clearance for class A but I would check the manufacturers website. They should all have tech sheets posted. Remember, just because it is only warm to the touch under normal circumstances doesn't mean it will be that way should you have a chimney fire.

 

Why are going 6" to 8" ?
You HAVE to have the THIMBLE/INSULATION BOX when going thru a wall/ceiling, there are no shortcuts or way around it to meet code around here. These deals are basically what give you zero clearance to combustibles.
You can usually buy these at Menards or Rural King. The insulated pipe I bought has a 3/4 inch clearance to combustibles.
NO SHORTCUTS on installing a stove or the flue pipe,,,pay attention to all of your clearances with the stove and your pipe.

 

Thanks guys! I do not have the thimble yet but was planning on putting a decent gap around the whole hole either way. Reason for 6to 8inch is I got the 8inch pretty cheap of craigslist. I only plan on burning when I'm thing to be on the shop all day and burning only dry dry wood so I'm not worried about a chimney fire.

 

This is more true than the values that Jesus has taught us. They don't like it because people store gasoline etc. in the garage, and they don't care if you don't either. Just a code thing.

 

Best to call your insurance company, mine had no problem with it what so ever.
Just follow the specs. of the maker of the pipe and you should be good to go.
The draft may be just fine going from 6 to 8 inch, some times you never know until you try.

 

Funny thing though I'll only be out there heating with the stove when I'm welding I have a pile of projects to do with the welder and would like to keep it warm. As I found on another post one day, the molten metal flying everywhere around my shop along with sparks and what have you is probably more concerning than a fire inside a steel box entirely contained in itself lol. Just a pain in everyone's a**if you ask me. Only takes a few to ruin it

 

shaggy wood dump hoarder , is your garage attached or unattached to your home?
The guys have all been correct in saying the Ins co will not cover your garage with a
woodstove in it, especially without an inspection from the towns building inspector
for a safe install including a permit. Is your garage a place of business? I know your
trying to keep yourself warm while you work on the cheap but you may be putting
yourself in harms way.

 

It's unattached. And no not really a business just some under the table work once in a while and stuff for family and friends and my 5x10 trailer for hauling wood.

 

Once again CALL your insurance company, mine had no problem as long as the stove had a UL tag on it (no home made stoves).

 

Very good point but some insurance companies have issues with welding depending on how the shop is built.

 

My insurance company is a "local" company so a good chance you will have better luck then dealing with a bigger company.
Brain cells seem to be much more intact here then other parts of the country.

 

They really had no problem huh? I meant to call this week but got caught up with New year's and getting my trim up into my old bed room turned wood shop for cutting sanding jointing and routing and staining. Let the long process begin!

 

Not a bit as long as the stove was not home made, they even sent me a paper with all the stove clearances needed.

 

State Farm gave me a tri-fold pamphlet when I asked about a woodstove. It had clearances and some other info about combustible materials. If i can find it i will put some info up here.

 

Thanks guys. There is hope after all!
