After reading your posts and seeing your photos. I would use this chimney. Fireclay chimneys / riser is what we use with rocket mass heaters. (In fact, I suggest you build a RMH instead of a wood stove)
Your stove man was doing his job. Class A is insurance approved. Like Travis I have no real fire insurance. I have had a few chimney fires in one of my previous homes. Imagine waking up to a freight train roaring thru your home. That's what it sound like ... add in glowing orange single wall pipes and its rather exciting (in a bad way) So I can't blame your chimney guy for being cautious.
Travis has lived his whole life with wood stoves. He has seen family homes burn to the ground... However his has not, neither has mine. We take care of our chimneys! Even a class A chimney can fail.
Properly burning your stove, regular cleaning of the chimney before each burning season. Don't put to much faith in the "creosote sticks" Instead invest in a few of the "fire out stick" They will stop your chimney fire while it is roaring.
Always have several fire extinguisher's mounted in strategic locations. If you have children teach them how to safely exit their bed room window in the event of a catastrophic fire.
Chimney fire's are scary. They can be avoided. Being prepared is the secret. Clean your chimney , burn DRY seasoned wood, Don't load up your stove then shut it down to smolder ... that causes creosote.
Wood burning is wonderful! Nothing beats snuggling up to a wood burner to pull the chill out of your bones! You can keep all those other forms of heating... I'll stick with wood!

At first I assumed this too, but after looking at the pictures, and your text, I think the stove shop owner is correct. the real information that is missing is the protection rating based on TIME. For instance, I think a Class A stainless steel triple wall metalbestos chimney has a rating of 2100 degrees for an hour. Your Van Packer is rated up to 2000 degrees, BUT FOR HOW LONG?
I could see where that type of chimney would be great for an oil or propane furnace because it was a cheaper alternative to masonry chimneys. But a woodstove has the potential to start a chimney fire and so it could indeed have a long burn time in excess of 2000 degrees for quite awhile.
Now if you find out the Van Packer has a fire rating of 2000 degrees for an hour, or is otherwise comparable to a Class A chimney, then I might use it, but I can see what the stove shop owner is saying, and why. But keep in mind, if you have insurance on your home (I say that because none of my houses do), they might have some impact on what you use for a chimney too.
