Efm has a handle that opens the cleanouts, not sure about the other underfeed stokers..
Greg, the Harman also has a slide cleanout under the grate that needed to be cleaned every 30-60 days, I'm talking about an ADDITIONAL fine collector on the back of the stove under the stoker's push block. This needed to be cleaned out every day for me (Harman said every week in the manual). I just thought this was normal to stokers until I started going through my KA-4!
This is what I don't see on MY KA-4, but coalkirk said it's b/c of the stoker design with the pusher block on the Harman. Maybe it creates a lot of fines with that design?
