Routing Chimney Pipe Question....Inside Garage??

So I've been doing a bit of daydreaming lately. If things go well I may be able to sell my house and build a house on my parents 15 acre lot in 4-5 years. I've been browsing through home plans because I've got nothing better to do.

I found the perfect plan but it did not include a masonry chimney anywhere. To save costs, going through the wall and going up the side of the house with double wall stainless is attractive to me. The clean out T will make sweeping much easier.

The problem is that the ideal location for the stove is on the same wall as the attached 2-car garage is on. It is acceptable to route the chimney pipe exposed inside the garage? Or must a chase be built around it?

Thanks!

I figured. Here is question #2. If I built a chase around the chimney inside the garage which is easy enough to do, is it common practice to have a access door or something at the bottom to access the clean out T?

That was the reasoning behind my initial thought. As long as 2" to combustibles is met, who cares? Of course something could accidentally be placed against the chimney pipe in the garage but that could also just as easily happen outside if I were going out the side of the house and up.

Great! Thanks! Which brings me back to question #2. Is it common practice to have an access door at the bottom of the framed chase to gain access to the clean-out T?

That is exactly how mine is installed. Not a question or concern from either the installer, or the inspector.
This goes from the stove room, through the wall to the garage, up through the garage ceiling, the garage attic and through the roof. Then, it goes up another floor on the outside and through the eave on the second floor.

BrianN....that is beautifull. That is exactly what I want to do someday. Super easy to sweep, and it gets some of the benefits of not being exposed to outdoor temperatures and wind, except for the cap of course.

A quick question. Have you ever measured the temperatures on the outside of the chimney pipe? I've always been curious about how much heat these chimney pipes keep inside.
