What is the L6006 dumpzone aquastat set at. The HL on the 8400 on the boiler should be set to 205 or so. If you keep climbing in temp with only the idle circuit active you need to go to 7 and then 8 minutes off if neccesary. I stoke for 54 seconds and am off for 6 minutes.

You may have to back down the feed rate.

My boiler has never hit the dump aquastat to my knowledge. You should only have about an inch or slightly less fire at idle. As long as you aren't dumping hot coals off the edge of the grate at high fire you need to extend your off time on idle.

From what I'm reading, I'd say you need to back off the feed rate even more for this time of year. My Kaa-2 is backed off one full turn from where I run it during the cold months of winter. In other words, coal is slow to respond. By the time your fire is alive, and cranking, you have way too much coal on the grate. The thermostat(s) gets satisfied, and all that heat has to go somewhere. You need to burn a smaller fire, hotter. This is done by backing off the feed rate, and having a little more "On Time". The hotter fire is faster to respond to a call for heat. Yet, this time of year, you don't want a dead of winter size pile of coal burning. I'm assumeing you have your fire running as low as you can get away with. At the same time, your feed rate is up. When a call for heat, the stoker starts pushing coal on to the grate. The low fire is slow to respond, but eventually does. By that time, the stoker has pushed lots of coal. You have a blairing fire. Too much fire. You need to find the sweet spot. Myself, I'll leave my feed rate one turn behind untill the wheather is cold enough to where the boiler is struggling to keep up. At that time(dead of winter), I'll turn the feed rate back up one turn. I add more pins (in your case, "On Time") in order to maintain hotter fire. Hope this points you in the right direction. Oliver
