:shock:

Ehhhhhh.......got a half load of charcoal burning......it's just a weeeeee bit more than I bargained for.

I was only going to burn a little bit (covering the base) but it was burning unevenly so I put a couple small wood scraps on and filled the pot about half way with Kingsford. Welp, it's going pretty strong right now and I've got it shut down pretty tight (both on the primaries and the MPD) and it's still pullin' pretty hard. I hope Kingsford has totally different burn characteristics than coal cuz I dunno that I can tame a coal fire with my chimney setup.......OR........I have a huge leak below the burn pot....and I don't think I do.

Anyhow, Phoeonix in Michigan!. :D

Still about the same at 10:20pm.

I went around the stove with a stinky stick thingy the wife had. There's a leak at the bottom of the ash pan door....I'll have to adjust it and try it again tomorrow.

I feel like Frosty the Snowman.....'gosh it's hot'. :D

Ya gotta like the pre-planning going on though!! :D

Firing up the stove in June to make sure it is all set for the cold weather.... :punk:

That seems hot now, . . but wait until it's -20 outside. :D

Was it in direct, or indirect mode ?

You've got a number of things going on that I think will make it want to burn hotter than it will in normal use.

I find that a fresh bed of coals always burns hotter the first day until the older coals in the lower part of the bed are burned out some and producing more ash. Plus they mesh closer as they produce ash restricting air flow up into the fire bed.

And yes, once it's going, the Kingsford burns more quickly than anthracite. Sorta somewhere between that and wood. Add to that, the Kingsford coals have bigger gaps between them - more like stove coal without the smaller bits mixed in.

With those bigger air spaces, and having only a half a pot worth, it will probably want to burn faster than a full pot. Your having the same problem I do when I use stove coal in the shallower bed of my range. It wants to run very hot even with all the dampers fully closed and in indirect mode, with water reservoir flues open to draw off more heat. I have to use the check draft damper built into the range to help control the strong draft. If I add nut coal, it helps close up the large spaces between the stove coal chunks and slows down the fire to where I only need the check draft at night. With using only nut coal, the firebed it is very controllable, but the dampers still need to be almost completely closed.

There's more you can do to slow it down.

If you find your draft is stronger than you like, experiment with check draft damper settings. That's why the Glenwoods back elbow pipe had a check damper built in.

If you use stove coal, you can mix in some nut coal to slow it down.

The old timers used to sprinkle some ash over the fire bed to slow a too-hot fire.

Paul, I will adjust the door pins this afternoon and run a mix of lump charcoal and regular Kingsford and see if I have more control.

It was running in indirect....and just like everyone has said, when I flipped the damper to indirect the stack temps dropped from 300 to 225 pretty quickly.

You may want to see what the check damper will do for you, too.

The good news is, . . it's far easier to control too much draft, than to overcome a weak draft ! ;)

I measured it when I was at Wilson's getting my #6, but I forget, what size is the firepot on your #8 ?

When I was assembling the stove I noticed the check damper was stuck. I oiled it and was going to work it free when I got heat to it.......but I forgot. I WILL see if I can free it up tonight.

That's one thing I have is a stout drafting chimney. My thinking prior to fire up was that too much draft wouldn't be an issue with much lower stack temps......tisn't the case.

I took measurements and pics as I was putting it together and I did try to post the pictures but failed (either NEPA timed out or my computer crapped the bed). Either way, I have the dims at home and will post them up when I get home.

If I remember, it's 18" at the top. I don't remember what it is at the bottom and I don't remember the depth.....but I'll post it all up later today.

I think you'll find that in actual use, with a full load of coal, it's more controllable then when experimenting with just a partial load of charcoal.

Yeah, I remember how wide it looked, and how skinny it made the other good-sized oaks next to it look.

That'll hold a lot of coal. The iron pot on my #6 is 15-1/2 inch id at the top and 14 inch id at the bottom. Take off two inches from each of those for the thickness of the brick liners. With the bricks in, it holds exactly 50 pounds of nut coal.

Imagine how much your #8 would hold if we could get magazine tubes made ? :shock:

Speaking of which, the swing cover plate on top, what diameter is that ?

The cover plate on my #6 is 8-1/2 inch diameter. It's marked Glen Oak 1901. It's the exact same cover as the one on my 118. So they both could very likely use the same magazine tube ????

When you look at it from the side.....that's when it looks huge to me. It's a big stove no matter how you slice it but from the front of the barrel to the back of the bypass damper is 3ft. It's a real porker.

Yeah, there's TONS of room above the fire pot for sure....probably 3 or 4 fire pots of volume.

I'll measure it up when I get home.....I know I didn't measure it at assembly.

BTW....$13.21 out the door for a big ole bag of lumpy charcoal from the local Home Depot.

Just about 18" dia (at the top) pot with one inch fire brick, about 14.5" firebrick to firebrick on the bottom, 9.25" deep.

The swing plate on the No. 8 is the same as the No. 6.

Porker is right. :D My #6 is only 29 inches out beyond the barrel at the front of the ash door to the rear most part of that back pipe damper cover.

Interesting - larger diameter pot, but not quite as deep. The #6 is 10-1/4 inches from the top of the grates to the top of the bricks.

So, it uses the same cover plate. That means it may also be able to use the same magazine tube as a #6, a Modern Oak 118, and other earlier Glenwood Oaks ????

Huummmm. . . . now all we need to do is find a magazine to have recastings made of. :D
