Thanks for the excellent pics...now I'm completely confused...just kidding. I agree they should be screwed together. Probably something stainless, but I would see if I could put a fabric/non-burning washer on the end where the coal is. Mine looked very different. I had a heavy cast iron hinged door which was covering the top of the hopper. On the top of the hopper was another cast iron piece which had a cut out for putting the coal in. Looks like yours is different for some reason. Looks like the area for adding coal is small and hard to pour into unless you use a coal scuttle.

I'm still trying to figure out where the rope would go. My best guess is that I screw the two together and it goes inbetween like a sandwich.
Loading is easy; bucket w/spout.

Mine had a grove in the cast iron cover. Yours may be as you said to give you a compression seal. My experience was there was not much combustion vapors/smells coming from the loading area as the pea coal made a good seal.

the other night I noticed, closing the top door, that there was a significant amount of air being sucked into the stove. Maybe my pea doesnt seal that well. Actually, it cant; behind and infront of the hopper there's a 3/4" air gap.

Yes,they are. My 713 has the same door and there are two hex head bolts holding the plates together. Between them is a gasket about 1/2" thick. I haven't had to replace mine yet. When I bought my Surdiac the previous owner gave me some gasket rope with a round cross section and some with a flat cross section like a lamp wick. I think the wick type was intended for this seal, though the one that is in there looks like one continuous piece. If you have a good source for Surdiac parts they should be able to tell you if there is a part number for the gasket. I suspect it goes all the way in to the lip cast into the upper plate. It sticks out beyond the edges of the lower plate so that it wedges into the taper of the opening. When I close the door there is no sound of metal to metal contact. The previous owner also suggested that I brush away any coal grit left in the opening when filling so that it wont chew up the gasket. A cheap "china bristle" paint brush works good. He warned against using nylon brushes since they can melt.

Thanks Bruce!
I discovered why mine arent screwed together- one of the bolt heads must have broken off an the screw is still stuck in there. I'll need to retap it next cool down.

My 513 seems set up different. The top sheetmetal door just opens by itself. The bottom iron door that goes on the hopper has a loop on it. You stick the stove tool in the loop and open it. My rope seal is under the iron door on the top of the hopper. Im guessing to keep gasses in or the draft from coming in.

Bruce,
Any chance you could send a picture? I just got mine drilled and temporarily bolted in place w/o a gasket. It clearly cant take a round gasket. I suspect I understand your setup, but a pic would be great.
Thanks!

Getting clear pics is not my strong suit. Looking at your pics there is a lip about 1" wide around the edge of the top door. The gasket sits on that lip and sticks out past the edges of the bottom door when it is bolted in place. The gasket should wedge in the tapered opening of the stove before either of the metal plates makes contact with the stove. If there is a one piece gasket it would be shaped like a frame. Or you might be able to build a gasket using layers of flat wick type gasket material.

That's what I thought it would look like. I'll hit the store tomorrow, and I should be posting numbers like the big boys real soon!

As Jersey said, I drilled through for a new bolt, then installed a 3/4 flat gasket (probably easier to do this cool; but where's the fun in that?). The lid still seems to hit metal/metal, but the gasket must be doing something. The temperature has jumped 100*! I had to turn the dial down a bit to compensate. Thanks for all your help!

Im sorry I cant post pictures of my Surdiac . Its just like your poasted picture. I have the exact same seal but its in pieces. :D Stoves in in the dark garage . But I did go out there and look at the door closely. And its as you say. The rope seal is pinched between the two halves at one end of the seal The door that is screwed togethers with two screws. And the seal lays on top of the hopper when the door is closed. Im getting that seal and the glass seal from Meyers Furniture. And Im getting my busted glass strips made here localy at $6.33 a piece. :shock: Meyers wanted $7 and that woodman s place wants $6 but I emailed him twice and they wont respond. Meyers jumped all over my email and put my order together and takes a check.

I have a question about surdiac 616 coal stove. Are the original gaskets around the doors asbestos. Should i take extra care during replacement and disposal.
