    I have an upland 207 I'm looking to install. It's going through an exterior wall on the first floor. There is a large section of wall that is brick for this purpose. the thing is, from the edge of the thimble there is only about 12" of brick before you hit wood studs. I thought that was too close to just use a clay thimble, so I thought I would use a section of 8" double wall pipe. Is this a good idea? Can I just butt the double wall up against the clay liner in the chimney and seal the seams with heat stop?

    It's a good 3 feet from the ceiling. The old thimble was already removed. I have the double wall hear that I can use. I guess maybe I could have gotten away with the clay thimble, but since it's already gone I'll just go this route if it's acceptable. Even if it's not the prettiest.

    I'm a bit leary of using the 8" double-wall for this purpose. The two issues of concern that I have are the long term seal between the chimney tile and the pipe and the awkwardness of connecting it to the stove unless you are using double-wall connector all the way to the stove.

    The end of the double wall joins perfectly with my 8" black stovepipe.

    It would be about 9" from the thimble to the stud on the interior wall. The joint between the double wall and the flue is also what was concerning me a bit, but I didn't think that having a thimble separated from a stud by 9" of brick was safe for a wood stove.

    9" is too close for a clay thimble, but now I am wondering what pipe you are using. When you say double-wall, is this class A, insulated pipe or double-wall connector pipe? If class A, you are ok. It just needs to be cemented up against the face of the chimney tile for a good seal.

    Ah, I very well could be using the wrong terms. Here are images of exactly what I'm looking to use.

    There are pics there of each end, and also one of how the stovepipe meets up with it. Thanks

    OK, no problem. Once you started describing it I thought you might be using class A. You should be ok, re-read the article and you will see this option mentioned as using double-wall insulated pipe.

    It's all cemented up, seems like a good seal. Thanks for the tips. This is in a separate workshop building, not sure I'm going to get good enough draft with the chimney that's in place.... but it's worth a shot. I don't have any cash tied up in it other than the black stovepipe. Would love if this works out though, sure beats a propane space heater! Will hook up the stovepipe and fire it up once the heat stop is cured. Thanks again.

    Take some pics! The webmaster here used to sell Uplands. He says they're good stoves.

    I definitely will. I have to clean up the area and hook my stovepipe up, hopefully test it out tomorrow night. The stove looks great, had one of the cracks on the back that I commonly read about, hopefully the heatstop on both sides will be enough to take care of it. Wish i had the screen for it, that seems like a pretty cool feature for when you are sitting by the fire.
