OHHHHHH> The exhaust only goes 8-10 feet up the chimney............ It doesn't go all the way to the top and out through a metal plate that is sealed to the top of the chimney and terminated with a cap?
New to this Pellet stove thing..... HELP!

I stayed away from the AS400 systems, did a lot of heavy iron work, a few midrange systems, some micro systems, and a few distributed fault tolerant systems.

Yea, that pipe should either go all the way up as mine do or there should definitely be a block off plate. In my manual, it tells you NOT to seal the plate since you want to remove it from time to time to clean out the soot. Making a block off plate is not an easy task especially if you also run a 3" air intake hose up there. Making one out of cardboard first would be logical as a pattern. I've wondered if cement board would be a feasible alternative rather than sheet metal.
I'm still puzzled about the 'vent in the back of the chimney' thingy. Finally, I can't fathom how an insert could deal with the concentric exhaust and intake.
Oh, and I played with C before there was a C++.

The stove can also go on a pedestal and be freestanding vented through the wall.

Feeling the Heat
I'm having my Harman insert installed in less than 2 weeks. I asked for an exhaust to the top of the chimney, a plate at the top, but one specially made with a screen around the bottom of the plate so I can run my OAK part way up the chimney. That is, rain is sealed off the top, but air is let in and the intake air is far away from the exhaust. It's in the install manual. Hope I'm doing it right.
Back on page one, the OP mentioned that they previously had a wood burning insert and they have a 'full length' liner installed. That's probably a 6" liner so his easiest fix would be to use a 3" to 6" adapter. Again the concentric intake is a problem unless the stove has an alternate intake for combustion air. I believe I've seen some that do.
EDIT: I've read the manual again and I see where on a horizontal installation you have a 3" and 5" concentric pipe setup like on a Bixby. For the fireplace setup, it's really a crude after-though, IMHO. Just stick the 3" pipe up past the smoke shelf and that's it. The intake air will then be drawn from the air coming back down the chimney.
With the cold air blowing out of the bottom of the stove, that indicates that something is amiss with the stove. Intake air should not be going anywhere but into the area below the burn pot. I would be pulling off panels and seeing why that air is escaping the intake plenum. Also, see what the path is from that lower vent to the room blower. Is there any path that leads to the outside of the back of the stove, which would allow chimney air to come down and out through that opening.
EDIT TO THE EDIT: Looking at page 20 of the manual, it appears that this system is a positive pressure system, rather than a negative system. If you look at the Bi-monthly cleaning, the exhaust pipe comes directly from the burn pot area to the outside. On the next page, if you look at the schematic, there is no vacuum switch, which also points to positive pressure. How does this enter into the equation? Who knows without tearing into it.
The more I read, the scarier it becomes! Make SURE you have a good carbon monoxide monitor in the room!
