This is the model 77 stoker i picked up in louisville. I have now piped it into the forced air system in my home. (bear in mind that i only spent about 3-4 hours on the install, so some of the sheet metal work is a bit sloppy) It manages to heat the house quite well. couple issues i had with it: the stoker/fan drive motor went bad, thus causing the pully/fan combo which was made out of alluminum to deform where the motor shaft went into it, i have ordered another one. in the meantime i have rigged another motor i had to run the stoker and a separate tiny fan to force the air into the tuyers. this stoker being so small is VERY picky about the air setting, too much, the fire goes out on startup, too little and the firebox fills with unburned coal, however, i was lucky as the little fan that i installed has EXACTLY the right amount of air flow so that it has been burning well for a few days now, without going out. the baro setting is critical as well, it basically has to be right at .04, no more, no less. I took out the small fan that blew air over the heat exhcanger and replaced it with a variable speed squirrel cage fan to get more air flow, the stoker, although small keeps up with heat demand quite well, using at most two 5 gallon pails per day.
One other issue i have run into is that my coal is such good bituminous, i cannot get much of a clinker at all to form. so once in the morning and once in the evening i shevol out the firebox around the burn pot, but not too much, it likes about 3" of ash to be left or the fire may go out. much of my coal is also too large for this stoker, so i set up a screen and sift out all pieces larger than 1". shevoling out the ash isn't that bad at all, and no dust is created due to the design of the stove, you open the fire door and right under it is a built in ash can with lid, so as you shevol in the ash, any dust gets sucked right into the firebox and NONE goes into the home, otherwise i wouldn't be burning it. even with my high vol coal, i get no soot in the firebox and only a light black/grey haze coming out of the chimney, yes i do have it piped right into the same chimney as my gas furnace and water heater.
