Yes, that is "Clinker-ing" if that is a word.

Ok, I've blocked the air almost totally off, raised the rear of the stove up and still have the same thing happening. Only difference that has happened is its pushed the fire lower down on the grate. Burning around 60-80lbs a day the stove is only around 240 outside temp. Any other suggestions? Thanks

Now slow the coal feed a little and wait a half hour to see results...repeat, until position is correct.

Don't give up!

There has to be a reason.

Is this a new stove or did you buy it used?

If it is a used stove just maybe someone previously replaced the combustion blower/fan.???
If this is a possibility, please go read the motor tag and tell us the mfg'r, model number and the RPM's.

:idea: At this point I suspect you have too big of a fan on this. :idea:

Bought the stove used about 4yrs ago from the original owner, family friend , older lady who only used it a yr and pretty sure its all original. Motor just says its a 120v 60hz and.50amps. Doesn't list any rpm's.

Well, if equipment all checks out and not the issue...how about try another coal source. :?:
Pickup a bag of different coal and see the results. :idea:

White ash perferablely...Blashack's

Have burnt blashack in all my past yrs and kimmels this yr all with the same result. No other sources to try in my area that im aware of. The stove is just so much hotter for the few mins its burning clean then when the coal is burning on top of some ash, just wish I could get to do that all the time.

I have a kast counsole, different stove same setup, I have the same problem but learned to controll it. Are you using a thermostate or the standard controll box?

Assuming a controll box,set on #2, knock all the clinker and ash off then spread the red coals out a bit and let run for 15 min or so to build a normal coal/fire bed. Now turn it up to #4 and let it burnfor a hour, the stove should get good and hot, knock any clinker off that forms. Then set it back to #3. The stove now should stay good and hot without any clinkers for hours, maybe 10 or 12 or at least till its time to fill the hopper

I never run above#4 and only for short hour long or so bursts when I do, depending on outside temp I ususally have to turn it down to 21/2 or even 2, I heat a ranch with stove in basement, 2400 sq feet for both floors thats the upper range for this stove.

If this don't work there is another underling problem and we'll have go over everthing from scratch,cleaning,gaskets,grate ect.

But don't give up it will get better

Your not using wet coal are you? If so try a hopper full of bone dry coal to see if there is any improvement.
When you replaced the grate gaskets did you use Alaska gaskets?

Sorry for all the questions but trying to get a full understanding I have this stove and with white ash coal this is rare so more questions,,,,,,,,,,,,,,

1 When you leave the controller set on 4 or above for 1 hour does coal spill off the side of the grate?

2 On 4 or above for 1 hour does the grate fill with fire except for about 1 inch at the end?

3 When on 4 or above does the fire darn near touch the top of the stove?

You mentioned in one of your posts stove temp, where is this taken from? If its above the fire door I could compare it to mine

1 No the coal doesn't spill of the side of the grate
2 on 4 its prob closer to 2" away from falling off the end
3 no the flame doesn't come close to reaching the top of the stove.

When I took that temp I believe it was just shooting the side of the stove itself. I can get a different reading else where if you prefer? Thanks for your suggestions

i am wondering what happened last year after this thread died in december, we had a very cold
winter the 2nd half of winter but I don't see where you came back and posted any more issues.
is there a chance that this is a condition of the stove trying to run slower while demand is low,
but during colder weather the increased coal moving thru kept the ash moving also?
