Stove pipe connection question

Hi all,
I have an older Quadrafire Mt. Vernon, not the newer AE model. Anyway, the exhaust blower needs to be replaced. I've got the new blower and gasket, I've disconnected all the electricals, removed the heat sheilds...and come to a dead halt. To remove the old blower I have to remove some bolts, but, the way the blower is located it is impossible to reach them from the sides, I have to get access through the back of the stove. The manual I have shows the back panel as being in 2 sections which each has a half circle opening which fits around the exhaust nipple on the back of the stove. Nice and simple to remove and reinstall, ofcourse the reality is different. The back panel of my stove is one piece which folds down but I cannot fold it down because the stove pipe is in the way. My main problem now is disconnecting the stove from the exhaust pipe. I removed the collar around the stove pipe connection to the stove itself and tried pulling the stove forward a bit and pushing back on the stove pipe with no results. Granted I haven't tried all out brute force or taking a rubber mallet to it or anything yet, figured I'd first see if there's any trick or anything I need to know or if it's just a matter of forcing it. Any helpful advice or moral support is always appreciated. Thanks

Those manuals are for newer models, they look about the same from the front but that's about as far as any similarity goes. I'm not sure how old my stove is, it came with the home but it is certainly not at all like the newer ones once you get beyond the outside appearence. looking through those manuals it seems the design engineers geatly improved the accessibility for replacing blowers. They have easy access to the fans and the manual has directions for replacement of fans, none of which can be found in the manual with my model. Thanks for trying to help though.

This is from the manual on the Quad web site. (http://www.quadrafire.com/Owner-Resources/Install-and-Owners-Manuals.aspx)

If you still can't remove it... with the bottom 3 screws removed, if you gently bend the bottom of the back panel out, would it give you enough room to pull the blower?

Another option would be to pull the entire rear panel & slide it all the way to the wall, if you can.
I don't know if that's possible since I haven't seen what your vent configuration is...

The 1st piece of pipe off the stove is a T turned on it's side, the center section of the tee is connected to the nipple on the back of the stove. The end of the top section of the T which faces up is connected to stove pipe runnning straight up about 5' then to 90 degree elbow and out through the wall. The end of the tee facing down is capped and I assume that is for clean-out and the reason there is a tee rather than an elbow. This is why I can't get the back open, I only have a couple inches from the back panel to the stove pipe that runs straight up. I did look closer this morning to the tee and it seems to be heavily caulked around the end that goes over the stove nipple, I'm wondering now that maybe that's the problem. Am I probably correct in assuming that with the collar removed the tee should just slide off the nipple? Thanks!
