Back Puffing

[HotCoals]

Close down the primary air at 600* jump up to 700* and one split has a lazy flame. hope that right.

Sounds good..the cat should come to life all on it's own soon.

 

[HotCoals]

I am now coming in to the burn zone. Usually I not have any flames but tonight I have some lazy flames licking the cat on the right. going to try and close down the primary air as soon as it gets to 600* to try a get a 10 hour burn out of this load. then off to bed and pray that it not overfire.

I cant over fire my cat stove with the air all the way down and I don't think you should be able to also.
Are you talking about super high cat probe temps or stove top temps when you say over fire?

 

[AppalachianStan]

Think so to it at 800* now. Just not use to see any flames

Both, but 1400* is the highes I have seen. and 650* on stove top with fan blowing on the gauge.

Sounds fine. You will not overheat that cat as long as flames are not beating it to death.
You should be able to get a nice 10hour burn easy in this cold if that box is close to 3cu.ft. I would think. The air needs to be all the way down or close to it.

I just loaded on some real hot coals 10 mins ago.
Already I'm 2/3 on my cat probe ..stove top 550 and the cat is getting brighter by the minute..I shut my air down just a few mins ago... had closed the by pass within a few mins of closing the door.
She is ready for the night.
Show me what you got mother nature..I ain't afraid of a little cold and wind..lol.

 

[AppalachianStan]

Is this a lazy flame? now it is 1000* with gas flames as will.

 

[AppalachianStan]

going to bed.

 

[HotCoals]

Yes,looks perfect!

Don't mess with it..lol. it will get better for awhile then latter the secondary flame will stop but the cat will keep on eating.

 

[HotCoals]

BTW..you do have fire alarms right?


Just joking but you should have some!
All will be fine!

 

[HotCoals]

Dang..now I wonder how his stove is doing. (broken image removed)

 

[AppalachianStan]

Made it though the night HotCoals. Yes I have 2 fire alarms and 1 CO. Only bad thing is I have no water.

 

[AppalachianStan]

I think the wind help the draft last night to get the temps I had. Now it is back to it old self. Load it up at 7:45 this morning took a hour to get it up to 800* and at 900* it started to back puff. pulled out by-pass rod for about a min and closed it back down to 1/4" open.

 

[Ashful]

I see you're at 11F this morning. That's plenty cold to where we shouldn't be blaming warm weather for your troubles.

At this point, I think a personal visit is in order. Any experienced hearth.com'ers in the Clover SC area, willing to go inspect and experiment with Stan's rig? There must be something we're just overlooking.

 

[AppalachianStan]

Up to the temp I was getting last night. Just don't understand the back-puffing with the by-pass rod open 1/4".

Stan its too bad you just can't find the problem with your stove. Do you have a dog house air opening on your stove ? If so I want you to try this. After you get your fire going up to say 600 on your cat probe and you close the bypass to engage. Open the doghouse up about 1/8 of an inch. Reason I say this is it sounds like your stove needs alittle flame after you get into about 1 1/2 to 2 hours burn cycle. Sounds like the reason for backpuff the stove is starving for air. The air from the doghouse is going directly into the bottom of the firebox and it should hold a small flame. As long as there is a flame I don't see how the stove would backpuff.

Not sure? But the air slider was closed but right now I am at 700* and no flames it was up to 900* and the slider is open?

 

[AppalachianStan]

Here is how the air flows

The 52 Bay manual states the doghouse air should only be used in the first 5 minutes of starting a fire and then be fully closed. From my understanding the regular draft controls should be used to control the burn.

 

[coltfever]

Wood not meaning this in a rude way this only a suggestion for stan because what we are trying to do is pinpoint what is causing his backpuff. He is operating his stove as he is suppose to its just not working as the manual states. This is just something to try only. The manual is not helping stan in this case. As someone mentioned to me on here about 2 years ago as long as there is a flame there is no smoke to backpuff and he was right.

 

[AppalachianStan]

Coltfever, is the dog house the slider under the door for start up air? Also remember the 52 bay menual is for the newer stoves. Also the newer stoves have 2 air controls on the door for the air wash. So the newer stove have 3 more controls that my stove dose not have.

 

[coltfever]

Yea Stan the doghouse is the slider under the door. I was looking at the picture of your stove and thought they might be a lot alike. But there not. Oh well scrap my idea.
I do wish there was something that would get you going like it should. Seven pages of info and nothing works. I have to say you haven't given up on it.

 

[AppalachianStan]

Coltfever. It is a nice looking stove and I just not have the money right now for a newer one. Make due with what I have until something better comes a long. I would like to get this one fixed. I hate given up on it. Some one may come a long needing info on this stove.

 

[AppalachianStan]

It is like I need to get more air in the box. Some type of control that can be close tight when it is not needed. Right now I have a box full of coals that I am trying to burn off with the primary air and by-pass open all the way. Temp have got back up to 800* on cat probe.

 

[HotCoals]

Stan the by-pass should be closed right now. You're losing to much heat up the flue with it open.
At times it sure does sound like a draft problem..maybe blockage somewhere,I dunno.
But from what you say it sounds like it could also be a intake problem...maybe a pressure thing going on.
