Wood Stove Chimney Question

[GabeFrederick]

Hi everyone. I used to have a brick chimney beside my house and when I dug out my foundation to replace the drain tile it collapsed. I am now in the process of building a chimney chase. The area where the flue pipe exits the basement is through the concrete foundation wall. What is the correct way to pass the flue pipe through the wall?
The old setup from the pipe to the foundation was as follows.
1. single wall pipe
2. insulation
3. thicker gauge metal pipe to hold the insulation around the single wall pipe
4. foundation

Thanks in advance.
Gabe

Typically there is a crock in the wall but a cut hole is fine too. You will shove a section of class A pipe in the hole through the wall. Fill the gap with any number of goops or even furnace cement. Maintain the upwards slope. Inside the basement you will transition to single or double wall connector pipe and on the outside you will hook to a class A Tee (cleanout on bottom) and then run class A vertical up to the cap. 2" minimum clearance to combustibles for the class A.

My black pipe from the wood burner runs to the basement wall. There is a double wall thimble .... actually a "T" ...... That goes through the wall and my black pipe connects to this. The "T" provides a clean out from the bottom and the support for the riser on the outside of the house for the rest of the chimney pipe.

If your going to burn wood it needs to be a class A vent meaning triple wall stainless, get a hold of your wallet...

I don't have an answer, but I recently ordered parts through chimney liner depot and they were great.

Acutally, it needs to be class A from the wall to the cap. Class A is not always triple wall. It is more often an insulated double wall and the outside is often galvanized vs. SS.

The black "connector pipe" can only be in the same room as the stove.

All the class A we handle is triple wall stainless. I'm sure there's other make ups for it what's important is the rating...

Must be a regional thing. You almost can't even buy that old air cooled triple wall anymore.

Yes, class A is the key rating. Yes, it is expensive. Often the flue system will cost more than a new stove.
