I have noticed for the last month or so, maybe longer, that VC has the Aspen C3 showing as "Temporarily Unavailable" on their website. I figured this was maybe due to supply or manufacturing constraints. However, some digging found this thread out on the internet, recently created: https://www.small-cabin.com/forum/3_10867_0.html
It claims there was some issue with missing data from the previous 3rd-party lab EPA certification of the stove. This would also be a plausible explanation for why it is unavailable. Ultimately I'm not concerned about mine and am very glad I got a stove at the end of summer when I did, but I will be curious to see how this plays out.

I'll see what my 2b Classic manual says for flue length, but the standard probably doesn't need as much flue since it doesn't have the upper chamber. Either stove should be able to cook you out of a 400 sqft space if operating correctly.
