how do you guy's cool the stove with overfire?

[Sprinter]

Unless I'm missing something, I only see a flue thermometer. Do you also have a stove top thermometer? In any case, a surface temp of 900 on the pipe would still be too hot for comfort, indicating maybe 1800 internal, but the stove may not have gotten all that hot.

Also, maybe it's the pic again, but I don't see any hearth for ember protection. Or is that a concrete floor?

Is that a stove top thermo I see? If so you seem to have a good handle on getting good readings on the top and flue. How are your clearances to combustibles? Hard to tell from the pics (stairs etc). From your original post you already know 900 is not a temp you want to see often.

Old stove but new to you install right? Combining being busy and having a basement install that is out of sight I would be extra careful till you know the stove is functioning properly (no air leaks) and that it is behaving.

I do have a thermo on the stove to too. that's what was 900 plus. it pegs at 900. at that time the flue was reading 250 or so.

I like having a thermo on both. I never thought of it until I found this little slice of woodstove heaven. in the pic I do have a few pieces of wood next to it. they are there ready to load. I was just burning down the coals to reload for the night. yes new to me. I got it from a customer who miraculously was 300 bucks shy of the invoice total. take what I can get right. I figured it was worth $300. is it? they used it daily and loved it but age was getting the best of them and was too much work. we put in a complete radiant system. new condensing boiler and all. used the existing baseboard as second stage. turned out very nice. I trust the stove. I got it in the middle of last heating season. I had a little old stove with removable plates on top for cooking pans. too small for me and burned wood like crazy. my wife is generally home all winter. she is my new secretary. I should have thought that one through first. lol I really do appreciate all that you guy's have taught me already. the difference it has made is incredible. now if I see a stove in someone else house I quiz them. lol

Only got scared once with my old stove, I put a couple pots of cold water on the stove. They transferred the heat away from the stove nicely while the fire settled down.

$300 doesn't sound bad to me. Did you give it the once over check the gaskets and so forth? As long as you can control the fire. They all get away from us once in a while just don't want they to be a daily event or your gonna have to come up with another $300 for a new stove sooner than later.

yes. everything looked good except two broken bricks. but no biggie. I have hit 900 a couple times and I don't know why it does it yet. it doesn't leak anywhere that I can find. I feel comfortable with it at 5-600. even 700 I can deal with. it's when the thermo is pegged I get a little nervous.

Do the dollar bill test on the door gasket. What's your flue setup like, real tall, really good draft? If you are not getting air from somewhere you're not supposed to maybe you could use a damper. Either that or start shutting her down earlier in the burn cycle.

LOL. I'm betting most of us do

Where is the stove thermometer placed? I couldn't see anything in the pic except something on the front ledge.

I think when an over fire is happening you tend to panic. Hard to practice a mock over fire. Maybe a 700 degree practice.

 

[BrotherBart]

Hard to practice a mock over fire.

Ain't hard at all. When the thing is rolling with a fresh load and the fires of hell are up top, open the freakin door wide. No different at 650, 800 or when I had to do it, 1,000.

What you do not want to have to do is learn, as a last resort, how it reacts when it is at 1,000 like I did. What you need is confidence that you can stop it. Before you have to. Wish I had.

I haven't done the dollar bill test yet. I really don't suspect a leak. it doesn't look like an oxygen fed flame. if you know what I mean. not much if any yellow. I truly think I am shutting it down to late as you said. but sometimes it will be steady at 4-500 for a couple hours, then it might shoot to 700. draft over fire .04-.06. I have checked a few times. habit I guess. and at breach is usually right around .08. as soon as I shut the intake the secondary's light off. good or not?

I have thought about adding a flue damper.

yes, that was it, on the top front edge. I have been moving it around checking for hot spots after it ran away.

you got that right. I just don't have any numbers to go by but my own tests and mistakes.

 

[Sprinter]

You may want to invest in an IR thermometer (under $20) and find the hottest spot on the top to place it. They're a good tool to have anyway.

Can't offer anything re the draft #'s but yes generally you want the secondaries to light up when you shut down but...big but, if you load on a big bed of coals that's a pretty good way to nuclear in most setups. But you seem to know that from what you've posted.

I think one thing maybe your missing is lowering the air in stages? I start shutting down at about 400 (also looking at the fire so no absolutes). 1/4 or so at a time. Depending on the fire I'm at my final set position by 500 or so. That peaks me at 650ish and I ride along that way. Each setup is so different though. Not just different stoves but locations in the house, chimney setups etc etc.

I have some. I find it easier to keep track of temp rise with the magnetics. I did use an ir to check accuracy of the mags. they are accurate at the surface.

I will start doing that. I have just been slamming it shut from the full open position.

But whatever you do, don't pour cold water on the hot stove!

even I know that and I'm just a dumb mechanical contractor. lol

I ain't a metallurgist but that cold water pot thing makes me wonder about rapid cooling of just a small portion of a lot of hot steel too fast. Don't know.

I don't really know either, but I would think that a large iron pot of water wouldn't be too rapid, at least if it wasn't spilling over at the time. But I prefer a fan blowing over the stove. It actually works pretty fast, and it's even.
