kaa-2 stoker question

is it common to get some coal comming out of the rear of the stoker on a kaa-2. it seems after a week of running i am seeing coal on the floor under the stoker just wondring if it is normal.

I'm having the same problem with my Keystoker Koker. I believe the response from Keystoker is to shut down the stove/furnace/boiler and look for areas which cause resistance to the coal's flowing from the hopper to the fire area. Supposedly sanding/smoothing any surface irregularity will allow the coal to flow unimpeded through the stoker mechanism.

I believe I've see more unburned coal when my furnace has more idle time, during warmer temperatures. Seems, with cold weather, with the Koker really cranking out heat, I see fewer bits of rice coal in the bottom of the unit.

I'm currently cleaning up these unburned bits of rice coal with a shop vac. I plan to screen out the ash from the unburned coal; and, put the good coal back in the hopper---so, I'm really not really wasting coal yet, it hasn't been thrown out with the ashes. It's just seems like a waste to see this perfectly good coal ending up at the bottom of the furnace ash collector.

My problem is so small, I don't plan on looking into the problem until the heating season is over.

i am getting a 100% burn no wasted coal inside the unit . the coal i am seeing is comming out of the back of the stoker where the adjustment is. the coal is ending up on the floor outside of the stove.

Does the stoker on the KA-4 & KA-6 do the same thing?

dont know about that maybe som ka-6 guys could chime in and let us know. i do know that the kaa-2 has the same stoker as a keystoker 105. the amount of coal is not much i say about 20 chips on the floor in weeks worth of time could be normal

I'd call Keystoker and discuss with them. Do you have this same problem even after adjusting the stoker adjustment knob?? It sounds like your stroke is just a little bit too long. Has Mike looked at the problem?? He has a 105K in his showroom. Might want to ask if he's ever seen this problem.

No, the stoker is completely different. There is no opening in the rear of the stoker mechanism.

I have a K6 and have the same issue with coal dropping out . if you look at your paper work you got with your boiler there is a exploded view of your burner unit . The Throat strap , #11, is held there and adjusted by a bolt on each side . the slott that allows you to adjust is where the coal comes out .I am going to use a larger washer to address this prob in the spring . WHen i use buckwheat coal i dont have this prob ,only when i am useing rice coal that seems to be real fine . hOPE THIS HELPS

thanks for the info but the stoker used on the kaa-2 is diffrent than the stoker used on a ka-6. the stoker i have is also used on the keystoker 90&105
