So, short -ahem, not so short- update here. After my initial, dare I say, quite successful (i.e. satisfying) burns when it was 45 F or so outside in the Chinook, I wanted to tackle two problems.
The first was somewhat minor: upon hot reloads, I got some smoke coming out the door when the first of the new splits would catch fire on the coals. To fix that, I was planning to change the stove pipe configuration from 2' double wall up, 90 degree double wall elbow, 2' single wall horizontal (and then thimble thru a concrete wall and masonry chimney with 24-25' external double wall rigid (no "vacuum hose undulations" visible) stainless "top-of-the-line" thick-walled or so I've been told by my sweep - I bought the home with this liner and that sweep did not install it, and other items in the home such as the oil furnace are also the top model of a brand line, so I trust him on that) to all double wall, two 45 degrees minimizing the horizontal run as much as possible.
However, when i tried to start my so far last fire (it's been rather warm here so I've been using the minisplit + solar electrons a lot), it just would not start. It was 35 F outside. Box full of smoke, even newspaper extinguishing before being burned completely. Tried 2 more times, including a 25 F outside temp. Same behavior.
I tried preheating the flue with a propane torch stuck through the open bypass valve. After 1 minute (btw; how long do you guys do this, when you do this?), the torch extinguished. Re-lit, same. This suggests that the CO2 from the torch flame can't get away. Suggesting a blockage.
Took off the vertical stove pipe and elbow, looked inside the cat chamber, vertical pipe. All clear, good.
Had a sweep come by (no access from the bottom, and only a small strip of roof accessible 2.5 stories up b/c of the solar panels - I don't feel comfortable going there...) to see if something had gone wrong; creosote blockage, cap (we had a storm before the last trial), or what have you.
None of that appeared to be the case.
However, looking carefully into the horizontal stove pipe going into the thimble, we could see that the flue in the masonry chimney had dropped by 1.5" or so. This resulted in a slight downward angle of the horizontal stove pipe (hinge-point someplace in the wall).
Clearly that's not good, and likely the cause of the stove not lighting.
I guess I'll have to have someone lift up the flue, and secure it with a top plate so it won't move again.
Question (
@bholler ?): does this happen sometimes? Was the liner installed in a poor way? Is it indicative of other issues I might have to (have someone) look at?
This all sucks as I have 17-18% maple waiting for me, it's (off and on so far) heating season on LI, and I am using oil
(off and on; I tend to not use the minisplit below 32 F or so) ...
Reputable companies are booked until mid January...
It's a winter different than I had expected; working at home but hoping to have zero heating cost between the wood and the solar electrons. ...
Anyway, hence my silence and absence here and on the "what's in your stove" thread to which I'd hoped to contribute - currently there's a load of unburned maple and sassafras in there, cold and lonely...
