I think most are placed near the stove for convenience. I think mine is about 14 inches or so above the stove top.

Next question: Is your stove a new EPA model or an older one? Most new stoves don't recommend a damper unless there is an extreme overdraft. I have one in my pipe for the purpose of slowing down a down draft when the stove is not in use so that the family room doesn't smell of creosote. But I NEVER use it during normal operation.

Agree. I didn't have a damper for my old VC, and didn't put one on the new Oslo piping either. Never had an excessive draft problem with my relatively short chimney. I can see the need for a damper only if there is a demonstrated overfiring problem that's related to excessive draft.

As for blocking the down draft smell in the offseason, a damper sounds like it would work as long as it seals well enough. I use a 6" thick foam rubber plug that fits tight in the pipe, and that I can put in through my cleanout door. Works great. But, I DO have to make sure I remember to take it out before I try to light 'er up!
 
the stove is very old with a 18' chimney. i have a problem maintaining the same temp or close to it so i thoght a damper would allow me to control the temp better. it seems like i go from 300 deg to 600 ALL the time. i would like to find a way to keep it in the middle with less monitoring. i burn several types of hard wood so im sure that plays in somewhere, but i shouldnt have to play with a 300 degree gap all the time.
 
Ours is 18-20" up from the stove top...double wall pipe take little finessing but you can do it.

barometric damper effects automatic draft control

What happened to the post about "turbulation"?

That is one super-de-duper word :ahhh:
