Ok guys, help me out. Last year, I installed my Breckwell Big E and it ran all winter. I decided to swap it for a wood stove after much deliberation. Here's what the crock looked like after the uninstall.

Mind you, it had a clean out T right out of the back of the stove which never had a significant amount of ash. So my first question is: Why the hell did all the ash sit in the crock and not the T? Second, is the coloring indicative of an installation issue or is that pretty normal? I peeled away a bit of the flaking paint and there was bright white plaster underneath. I did not use a masonry crock adapter.

I'm purchasing a Woodstock Progress Hybrid as a replacement for the Big E. That sucker is 700 lbs and I'm hoping to prevent the need to move the stove to clean the crock. I'd like to hear your thoughts on the most efficient way to vent this stove. My plan is to use a clean out T and a masonry/pipe adapter. A couple of numbers to work with:
  • The stove's rear flue height center with standard legs is 27.75".
  • The stove's rear flue height with short legs is 22.75".
  • My masonry flue center is 33".
  • I can build a custom hearth pad if needed.
The website doesn't really say if the height of the stove (33.5") includes standard 10" legs or not. If not, top flue venting is not possible. If so, then the short leg kit would reduce the height by 5" but I'm not sure that's enough. So, top or rear venting? Least amount of pipe while maintaining safety?

Your thoughts are much appreciated!

As for the height/pipe considerations - send your pics and measurements over to the good folks at Woodstock and they will answer your questions very well for you - they know the stove measurements quite well and can guide you.

As to why the ash collected where it did - I'm not entirely sure, but clearly being a horizontal section of run it was a good place for it to settle. My question is why did not not expect to see it there? What is the rest of your chimney setup like? i.e. what is on the other side of that hole? Is there another clean-out over there that is full?

I seem to be missing something obvious here...

Thanks for the reply! I've heard that said about Woodstock and will definitely consult them.

The crock goes back about 12" and then ascends through the second story and out the roof. There is no clean out built into the chimney. Sounds like this is something I am stuck with ...

Ok - then given my mental image of things, it seems that ash would fall down and collect at the bottom of the chimney and, well, that happens to be right there with that 12" horizontal run. Question then is why did you have so much there? Was the chimney cleaned top-down and the horizontal section not brushed out? How long since it was cleaned out? That looked like a lot of ash to me to have just fallen down on it's own.

I expect you are going to be stuck having to pull the chimney apart and clean out that section each time you do a chimney sweeping - i.e. remove your stove pipe from the inside and clean out whatever comes down the chimney from the inside. On the bright side, with your new stove and good burning habits you shouldn't have much to clean out each time.

That ash built up over the whole season after 5 tons of pellets. Should I bother with a clean out T, then? Is it possible to clean it without moving the stove? Anyone ever tried a rolling hearth? This guy talks about his and has some pictures. Looks like an interesting route.
 
Once you get the stove in place take some measurements and see if a local metal shop could make you a rear vent exhaust that will fit. Maybe some kind of 2 section slip pipe that can be be disconnected, slid together and easily removed for cleaning without moving the stove.

I built my hearth pad for my Progress Hybrid and it had to be pretty heavy duty to hold the 700 lb, AND the size requirements for such a big stove are pretty big as well, they say a minimum of 54"w X 48"d but the ones they sell are 60" X 48". I built one that's about 62" X 50", and raised it 6" for ease of loading and appearance.
After framing it out, putting in a layer of 3/4" plywood, a layer of 1/2" cement board and covering the whole thing with slate tiles it was probably between 200-250lbs alone. Then that super heavy soapstone stove made it close to 1,000 lbs... Moving it might not be an easy proposition.

Have you made sure the wall space you plan on using is wide enough for the stove? The non loading side of the stove needs 8" clearance, the loading side needs 18" so you need to have about 34" from the center of your pipe to the loading side edge of your hearth pad to accommodate this stove, your wall doesn't look that wide based on the pipe size, and if it is, the stove pipe will most likely have to come out of the stove and then at an angle to get to that hole.

I'm not trying to rain on your parade but I had to do a lot of the "figuring out" myself and actually had to send back the first stove I ordered (which cost only $275 with my company's significant shipping discount) because I ordered the loading door on the left but realized the way my chimney sat hidden behind the wall required the door to be on the right if I didn't want the pipe to come out at an angle.

Here's a picture of my install:

You can see how the pipe had to be left of center to give the proper clearance for the loading door on the right.
