I hate to be another newbie asking the same questions, but if you don't mind another one of those posts... I want to make sure I have distilled what I need to know over the past 2 months of reading here. We* are currently "refinishing" our basement (it was finished 30 years ago, we ripped out paneling, reframed, insulated, etc). This will be a multipurpose room, so we will be using it. The house is a split-foyer. We are patiently waiting for the new Englander stove, so at the moment we do not have a stove, specs, or installation instruction. But we would like to get our pipe in now so we can finish the drywall. We would like to use the Selkirk Direct-Temp Up-and-out configuration with a corner install for aesthetic reasons (I don't want to see the OAK snaking up to grade). I am thinking we will get one piece of the 14-22" adjustable to account for not knowing the exact height of the exhaust. I think my 45 needs to go between the stove and the T, but I'm can't figure out which pipe to get here. It looks like the pipe before the T is not the dual-chamber pipe, but the direct-temp 45s seem to be all dual chamber. Here is one picture I found. Any suggestions? View attachment selkirk_dt.gif Our pad will be 45x45" of travertine over concrete. Sufficient size for most stoves? The exterior wall is cinder block and the interior is typical 2x4 framed for a total of about 13". The thimble extends to a max of 7", but this is OK because we only need the thimble on the interior portion of the wall, correct? That is, as long as we have half of the thimble extending into the wall to overlap into our cinderblock wall, I think we are OK. Direct-Temp is a 4" pipe, so I'm not so concerned with EVL. But my plan is to have a 36" and a 14-22" vertical section inside the basement for a total between about 4' and 6' up for draft (is 5' a min?), 3' through the wall (to go out at least 18"), 2 90s and one 45. So 18-19 EVL. Does it sound like I am missing anything? Would it be best to just put in the thimble and horizontal run now and worry about vertical pipe and 45s once we get the stove? As I mentioned the new stove from England's Stove Works is what we want, but we may give up if it doesn't become available soon. And since you like pictures, here my mockup (although there is more drywall up now, it all up but the sheet where the thimble will be). View attachment install2-3.jpg * I say "we" to mean mostly my husband. I do the internet research and distill it down, but he does 90% of the work. He is an electrician by trade, but had done just about everything but serious plumbing. He just finished a bathroom addition.
