Yep, that's for the stove, not the pipe. You can install it at 12" with single wall if the pipe is shielded, so technically it's correct. But most decent manuals would have a footnote telling you this.
Not sure about the Amesti. I haven't looked at that manual. Are the instructions even based on US or Canadian code?
Seems like we've had this discussion before?
Default clearance for single wall chimney connector is 18.0" per NFPA 211.
If a UL listed unit tests with the single wall closer to combustible walls than 18.0" it can be listed for installation that way. In other words, if, during the UL testing process, the wall temperatures behind the chimney connector do not exceed the predetermined temp. limits, you may say that the chimney connector on that particular unit can be installed closer than 18.0".
This is not that uncommon in the industry; as an example, the Morso 1410 has an 11.0" clearance between single wall chimney connector and NFPA unprotected surfaces. The Jotul 118CB lists a clearance of 13.0" from single wall chimney connector to NFPA 211 unprotected surfaces.
You may have a hard time convincing a local code enforement official of this, but I can assure you it is a safe installation.
