Got a problem, looking for ideas.
Wednesday last week, the day before Thanksgiving, it was -5dF here and I had the house at +83dF no problem (+78dF in the back bedroom) with the Tstat on 2, that would be 3 oclock on the swoosh.
Let it burn out and brushed out my flue Wednesday night. Then we had people over and kids home and moved furniture around and brought the tree in and moved furniture again, just holiday family chaos for a few days.
But I got some symptoms that aren't clearing up now that the chaos is over. Since I brushed out the pipe ten days ago, using the same wood as I have been all year:
1: Instead of a clean (<10% Ringlemann scale) detached plume, I have, at -10dF an attached plume that is >60% on the Ringleman scale. It is smoking bad. I am not an EPA vertified VEE, but I can by God read a Ringlemann chart. When the stove is running right I have a detached plume down to -20dF at least, maybe -25dF. I am accustomed to seeing Ringlemann's under 20% after hot reloads as fast I can get my boots on and get out there after engaging the cat.
2. Humidifier is using a lot less water than usual.
3. Snuck into my stash of really good wood, even running 14%MC with the Tstat on 3 (5 oclock somewhere), I am struggling to get the house up to +73dF. And it isn't cold out yet. I am wanting to save the half cord of really good wood that I do have for cold weather.
4. Burn times much diminished. I don't even want to talk about it. 6 hours maybe on what should be a 12 hour load. I am thinking about buying a bellows....
5. Active flames don't go away, no or very limited flame show. I was, (and still am) seeing some of the flame head for the bypass door with the cat engaged.
6. Ecofan base IR temp peaks at +177dF with the cat probe waaaay up into active, I am used to seeing 250dF+++ when the cat is that hot.
So this morning, Saturday, I let the stove burn down again, lifted the pipe off the collar and went looking at the bypass gasket. I was hoping for a chunk of charcoal on the gasket from when I brushed. No joy. I did find a bunch of powdery ash around the outside of the bypass gasket. I got after that with a smallish paint brush - it might have been a thick enough layer to keep the bypass door from sealing tightly.
While the stove was cold I tried moving the window in the door frame, it is solid as a rock. I also took a really really thorough look at the door gasket, it looks fine.
Fired it back up, it is running "better", but not better enough for me to just post "be sure to brush the light grey fly ash from around the bypass gasket when you sweep bottom up."
So what else can I try tomorrow before I call my dealer on Monday?
Dollar bill test, check. I got to let the thing burn out again and dollar bill test the door gasket. I don't think that is the problem, but my dealer will ask if I have tried it on Monday if I do call them. I'll do it.
Visual the pipe. With the stove cold I am going to lift the pipe again (thank God for telescoping pipe between the stove collar and the ceiling), shine a bright light up there and take a good look. I got a cup, maybe 1.5 cups of ash out when I swept last week, very normal unimpressive boring sweep. Didn't bother to visually check the pipe after sweeping, should have. 600 lumen flashlight should be adequate.
I am going to put every lumen I can into the firebox with the bypass closed to see if any light leaks though the bypass gasket into the upper smoke chamber. I can probably fit 1000watts of halogen goodness in there. If I see nothing, I'll try putting light in the smoke chamber and stick my head in the firebox...
What else can I / should I try tomorrow after church with the stove cold again?
Fool thing was running just fine until I brushed the pipe... I just can't really credit warped steel at the bypass gasket, the kids that were home keep their cotton picking hands off the durn stove because they aren't tired of breathing yet. The one kid who does operate the stove my way was in Arizona for the holiday.
