The wall that you currently have a round hole for the auger,my idea would be to remove that section... no round hole... just make a half-moon in a 2x4,screw it fast under the auger for support. That way when you want to take the auger out someday,just unscrew the 2x4 which will be easier then pulling it thru that hole.you don't have to support the very end of the auger tube which means nothing would block access to the end of the auger. Coal will only flow a couple of inches past the inner end of the dog box.Under the dog box would be empty space where you could stick a shovel in under the auger end & pull out some coal periodically to get rid of fines or if oversize object gets stuck in there.

Ahhhhh "Now I see, said the blind man to the deaf mute"

My head is starting to hurt with this plan. At least with a boiler, the 65" from the base to the bin side of the doghouse is what you get when you connect a standard 5' extension to the pot auger. And as shown in Figure 5, at the end of the extension the auger is about 2" off the "floor". Unless somebody already cut your extension - or unless the stoker mount on the furnace is way different from a boiler - it shouldn't be 6" off the floor. And while we're at it, why is the pot auger sticking out the end of the pipe???

Aside from the auger itself, I fear the bin dimensions and furnace/auger placement mean you will wind up raking or shoveling virtually all of the coal you use, largely defeating the purpose of delivering coal to the feed bin (i.e., if coal enters the bin at an 8' height, it's not going to flow much beyond 8' from the wall, so half of the bin capacity will be taken up by coal that won't flow naturally to the auger, and anything over that will need to be shoveled or raked at the time of delivery). Even worse, using a feed drum like the Mayor suggests would be almost impossible, because you'd have to reach over the drum to get at the approx. 1.5 tons that would remain in the bin after natural feed to the auger ends. Sorry to be a wet blanket, but this bin plan sounds to me like more of a hassle than a convenience.

Your Head is hurting? I'm having to take pain relievers... lol

Ok, the 65" distance is making much more sense, the extension auger I got with the furnace must be the standard one as it is about 68". Where the stoker assembly bolts I'm thinking it is pretty much the same as a boiler except that the plate is rounded where it bolts to the furnace (didn't take those photo's yet). Yea, the instruction do show the end close to the floor, so now that give me an idea...I'll explain shortly. The pot auger is just setting in the pipe to give me a visual to help me figure angle and hight, the pot and stoker are just temporary installed for the same purpose and for placement of the furnace.

The bin has a somewhat centered opening and that was originally designed for filling a bucket. We had 2 tons of coal delivered and the guy put the chute through the opening and did a nice job of filling the bin without doing any raking, however when I fill it by hand it does take a bit of raking. So pretty much the barrel idea is not going to work. Here is a quick sketch I drew (running out of time at the moment) and I know I will loose some capacity but still will get at least 2+ tons in there. The end where the auger would go would be raised about 2" and extend about 2' to the ramp.... Its a rough guestament. This should work?

OK, here is what I am up against, why the location of the bin feed. Some what going by the installations instructions for minimum clearances of 24" sides and back and the 18" for the stove pipe, but while I was measuring that it dawned on me if necessary I could use the opposite side outlet.

Here is a simple drawing of where the furnace sits at the moment, numbers are inches.


The box with RD is the return duct of the existing furnace, the little circle in the back is a round floor support.

Distance between the pole and rear is for access to the blower fan, motor, and air filters they go above the blower.

Also for alignment to the existing return duct.

This gives me room to walk around, stoker access, and meets the 18" requirement for the stove pipe as the return duct is fiberglass but I don't think the covering is fire proof.

Happy now Mike?


So I could move it back and to the right a little to get the bin auger lower and more centered in the coal bin, but then it would be a compromise for access and clearance's and I don't really think that little bit would make much of a difference. So suggestions what I may be overlooking?

Oh, one other side note... I need to make sure this work as I received this email from my wife Monday.

Hmmmmmm........ What a small world ! ....... We may very well be related, I think I married her sister.

Paulie

Well Paulie, maybe somewhere along the line... lol

She forgot about the Radiant Gem, but at least it isn't going down in the basement, so I'm good there.

Well... decided not to chance the gooseneck with the hole and I got the replacement gooseneck, gooseneck feed pipe and auger curtesy of Scrapper so good to go

And was able to get the two front panels on... so making progress I did end up moving the furnace back and to the right a bit.

Looking good. You will be shocked at the heat that thing puts out.

Getting most of the parts downstairs ready for reassembly... Now what did I do with that instruction manual?

Making progress, working at it little by little last few nights and beginning to look much more like a furnace.

Here's a few more photo's

Dude that is just looking pretty darn sweet!

Well...*cough*...uh...man you have my utmost respect. That’s one thing I don’t think I will ever hear my wife say!

Haha, at any rate this is the first time I get to see one of the forced air units taken apart and rebuilt. Nice to follow what you are doing here.
