Is this normal

PostBy: coalloser On: Fri Jan 09, 2009 4:22 pm

I took these pictures last night. Over the past couple of days, the flames going up my pipe has drastically increased. It sounds like huge vacuume of air. This even occurs with my draft controls on the ash door completely closed. The baro damper is wide open at .02. Is this type of activity normal? The draft seems to be coming from the bottom of ths stove, up the front of the coal bed, across the top of the stove and out the pipe. I have never seen this or heard it before.

What's up with my stove?

Your stove is sucking air in somewhere. Check your door gaskets, look for any cracks in the stove itself, etc.

You mention the draft contol is closed. Did you tighten the knob so the innner plate slide is sealed tight up against the stove? Is the ash pan door obstructed by any ash or coal debris preventing it from closing tightly? Are the gaskets on the ash pan and fill doors in good order?

Did you fix this problem? Looks like there is not enough coal being burned, maybe only half of what it should be.

I think so. I replaced all of the gaskets, window, door and ash door. I still have some blue ladies racing towards the pipe but nothing like the vortex I had before. Now I am just trying to figure out how much draft to give the stove to push a long burn 8-9 hours. I am getting close, Sunday left alone for 7 hours burned at about 500 degrees all day around the 8th hours started to die down and I saw dead spots forming on the coal bed. Monday, cut down the draft to 3 quarters of the vents open on the ash door, after 8 1/2 hours I had a lot of clinkers and about a 1/3 of the coal bed burning (also had the blower running almost full blast). Today, I cranked the vents down to 1/2 and also turned down my blower. We'll see around 5 tonight how this experiment went.

That's interesting. The flames look neat. I wonder if the cold outside air temperature created a higher draft than the barometric draft regulator could handle. Just a thought.

An observation! Maybe worthless, maybe not!

At the top where you elbow goes in to the block wall I think I see some discoloration or could be just a shadow. I have no idea what is up there but you might want to check the temps up there and possibly consider a heat shield. Elbows and 90* turns can get mighty hot and I know I would feel much safer with a heat shield above yours.

Set with a manometer or just with the 'markings' on the barometric?
How big is the chimney flue?
Setup looks good, is that pipe 18" from combustibles?

Something doesn't look right :notsure: I don't think you have the baffle in correctly. It can be in an "up" or a "down" position. It appears it's in the down position, unless the photo is deceiving. In the correct "up" position the flames/flue gasses are literally pushed forward toward the fill door, and would have to curve over the top of the baffle and then back to get up the stove pipe. In your photos it looks like the blue flames are going straight up the pipe :?: Or maybe it's just installed flipped 180*? Like I said, something doesn't look right.

The other possibility is mine is installed incorrectly, as I have never seen a manual for my stove :D But it seems to work fine the way I have it configured.

I guess the difference is that your stove pipe comes out the back of the stove whereas mine exits the top of the stove so you must have to position the baffle in your setup differently :idea:

millworker - you may hit the nail on the head - i just changed it around to the up position. The entire bed of coals seems to be burning now versus when it was in the down position, the fire seemed to burn only in the front

no more ladies leaving the party!

spoke too soon - loaded some coal on for the night came down after shower and I am just getting blue ladies in the front nothing else throughout the coal bed/ The more draft I cut on the ash door the more blue ladies fly up the pipe. You can only imagine how frustrating this is getting

I don't know if this helps, but here's a pix of how my baffle is installed. I was able to take a pix when I was loading. As you can see the baffle is out of the way of the coal , but makes a nice shield to deflect hot stove gases from shooting EITHER out the back or through the top stove pipe, depending on the configuration. In the current picture I wouldn't consider my stove anywhere nearly full. I can continue to load the coal right to the top of the firebricks, and even mound it above the firebricks in the center. In your photo it looks like the baffle is really close to the coal, and would prevent you from really filling it up??
