Flue install - stove to wall thimble

[tvm2299]

I'm replacing the stove and single wall flue in my basement with a new epa non-cat stove and Selkirk double wall pipe to the existing wall thimble and stainless chimney.

I bought a 24" section, a 90, and a 12-18" adjustable section. The stove is a couple inches taller than the old one so this puts me about 2" too high to hit the thimble. I'd like to replace the 24" with another 12-18" adjustable section and a 6" piece.

Is this allowed? I still end up with 24 1/2 inches before the actual bend in the 90 starts but will have about 22" of vertical pipe out of the stove. Everything I've read says 24" minimum but I don't know if that's a hard rule or just best practice.

Thanks.

Yes, it's allowable. Make sure the horiz section is sloping uphill toward the thimble by at least 1/4" per ft. Do you need an adapter for the flue collar? If so, that might replace the 6" starter.

Yes, was planning on doing the slope. Not sure if i need the adapter. Its a timberwolf 2100, the collar on the stove fits right between the inner and outer of the double wall pipe pretty well.

That's cool. Some stoves need them and others don't.
