Wood Burner, run stove pipe through floor
I am very short on cash right now and just found out I wont be able to use my chimney for my wood burner.
To save on money I know there is a way you can run a single stove pipe through my upstairs floor and then use a class A chimney pipe to go through the attic and roof.

How would I do that. I know I can use heat shields. What are the requirments to run a stove pipe through a floor? Building it is not an issue I just dont know whats legal/safe.

I have never heard of being able to do what you want. When a woodstove pipe passes through any horizontal structure (floor or ceiling) it is normally required to transfer to double or triple wall pipe. Check with any fireplace business in your area for local codes. Also, be sure to check with your Homeowners insurance. I checked and found that a wood "stove" (freestanding unit) would raise my rates by 10% while a built-in fireplace would not raise it at all.

You need to check with the stove manual. But I think you need a class A once you hit the first ceiling.

The people on will know also... but they'll tell you to look at the manual.

Class A chimney as you know is not cheap. Also the chimney goin through your 2nd floor is going to need to be boxed in so nobody/nothing can accidently touch it.

Whew, no offense, but have the fire dept. phone number handy.

If you have the jitters about doing it and don't know where to get assistance you may want think twice and go a little in debt to have a pro do it.

Than there is the permit, caught with an install with out one on a wood-burner around here is big bucks fine and if you can't afford to correct violations your only other choice is to dismantle the whole job.

You'll need an all fuel chimney.
They aren't cheap.

You can't just run a single wall pipe.
