Hand Fed Coal Stove: Syracuse Stove Works, No 4

Post by jkashoto » Tue. Dec. 06, 2022 7:32 pm

Hello all,
I recently picked up a small potbelly that I plan to put in service next year. I have a small building (16x24) that will be well insulated. I was looking for a small stove and I think I found it.
It's a 'Syracuse Stove Works No. 4'. I've torn it apart, checked the castings and sealed it up. The grates are excellent, the castings are well formed, no cracks.. etc.
The former owner put some decorative paint on it that I'm sure will disappear in the near future. I'll try to attach some photos.

My question involves the flue. Using a string I found the circumference to be slightly over 14 inches which, if my math is correct, equates to just about 4.5 inches. I intend to use double wall above the damper. I grew up burning wood but our wood stove was 6 inch flue from stove to top. What are your thoughts on tapering a 6" down to 4.5"? Perhaps it'd be better to use 5"?
Thanks for your thoughts
-mike

I think it is just going to be a matter of what size pipe will form down to that oval shape

Welcome ID
That's a very pretty stove.

I'm not aware of any 4-1/2 inch pipe available. You may have to cut strips of sheet metal to put inside the pipe as spacers between the 5 inch pipe and the stove's pipe collar. Or cut a long taper to the seam of 5 inch. I cut sheet stainless steel to make a tapered pipe for my kitchen range to transition the 7 inch oval pipe collar to a 6 inch round pipe.

The string method is fine but doesn't always equal a true pipe size. I'd cut a strip of cardboard and tape the ends together around the collar to see what size circle it forms when taken off.

You can run 5 inch into 6 inch pipe..... if you can find a tapered adaptor.

Hi Paul,
Thanks for the ideas. I repeated the measurement using some acetate. When I let it spring back round it measured 4.5 inches in diameter. I hadn't considered the spacer approach.

Or, solve two birds with one stone.

If you were to make a long cut up a 6 inch pipe, then squeeze the end of the pipe to overlap the two cut edges so they fit snugly over the pipe collar, clamp them, then drill and rivet them together. Then mash a bit of stove seam sealer into any gaps in that seam, that would make a tapered 4.5 to 6 inch pipe.

Thanks Paul...
I may give that one a shot and see how it turns out. I appreciate the thoughts.

Put rope gasket glue around breech collar. Wrap 30 inches of 1/4 round rope gasket around it, like a coil spring. Squish 5 inch pipe over the rope. Apply a hose clamp or 2 little screws.
