I finally got our ashford 30 installed today and while I know I have to build a chase yet around the chimney going through the second story I did a break in fire today. My question is how hot should the outside of the class A get. Definitely was hotter than I would of thought. I could touch it but was hot for sure. It is icc chimney.

Well class A has a clearance to combustibles of 2 inches so it should not be too hot. 130 - 150ish on surface?
I’m guessing it was in that range but considering I wasn’t running the stove that hard I thought it would be lower.
I was cranking the stove at 668 F stovetop. I have about 4.5 feet of single wall before the class A. About a foot up my first section of class a chimney it was reading 137 F with an IR gun. I pointed the gun on the factory certification label. When I pointed the gun at the bare metal it would read 72 F. I know that was way off. At the next section of pipe it was just lukewarm. If I had the ladder handy I would have felt the pipe at the support box, but Im guessing it was probably room temperature. When the stove was just cruising the first section was barely warm on the outside.

Just as a reference, 130degF is about the temp where you could hold a hand to it. Above that, too hot to touch for more than a few seconds. Mine is usually that or just a little more.
My class A is barely warm. I had an exposed through the wall T and then up 18 feet. I can put my hand on the exterior portion of the T and it's barely warm. For reference, the hottest I've ever seen my double wall stove pipe before the class A is around 160.
