    I'm over at a friends place looking at his Harman Exception stove.

    He has had the linkage to the bypass damper disengage a few times, so he called me to take a look at it. What's happening is that the internal rod that manipulates the bypass damper slips out of a slot in a bracket connected to the back of the damper. There's a bit of side-to-side play in the damper itself, and if the damper is slid all the way to the right (away from the rod), then the rod slips out of the channel that it should slide in, and the linkage is disengaged until you get in there and slide the bypass back over to the left and back into engagement with the rod.

    I would expect that there is some kind of mechanism that should keep the damper from shifting out of position, but don't see anything like that.

    Anybody have any experience with this thing??

    Yeah, gonna need some pics. Sound close to how the Encore works. There is some play and movement, but once the rod is in place, it is hard to get it to slip unless you really get creative. Not sure about how the harman is put together.
