I'm looking for class A chimney pipe

[chris-mcpherson]

I've chosen a local stove supplier and installer but he's quoting me $2500 for the chimney pipe. I'm paying $2400 for the stove!
So far I've looked at Woodland Direct and would like suggestions of other on line retailers, especially Hearth.com sponsors, that are recommended.
Also...should I be looking at double or triple wall pipe?

You should look for UL 103-HT rated Class A chimney. Selkirk and Simpson are big makers. The Selkirk is double wall..eg: 6" ID and 1" each side of insulation = 8" OD. Sometimes it's 6"ID +2" +2" = 10" OD.

Why is that better than the DuraTech pipe I'm looking at?

 

[dougand3]

It's not better...that's what Duratech is...Made by Simpson - UL 103-HT rated Class A chimney. Point here is: don't worry with terms of double wall or triple wall in regards to Class A chimney. "Double wall" refers more to stove (or connector) pipe that travels from stove to the first wall or ceiling penetration. After that penetration - it's all Class A to the rain cap. So, you need either single wall or double wall "stove pipe" from the stove to the wall. After that - think Class A chimney.

This is what I'm looking at:

I'm seeing an option of both double and triple wall in the class A pipe. There must be a difference.
I'm sorry if I'm missing somethig or not understanding.

I see. Woodland does label their Class A as double wall (Duratech) and Triple wall (Duraplus). Both are UL 103-HT. It says the triple wall stays cooler on outside, therefore hotter on inside = better draft. Will that have practical terms for you? Unless you have a marginal draft situation, I doubt it will matter...but I am guessing here. Maybe someone who has used both will chime in.

Thanks...I at least wanted to make sure I was looking at it correctly. I'll talk to my installer to see if he has an opinion on which one to use.
