Hello all.
Thank you for all the information. This year I needed to take the burner assembly off and replace all the rope gaskets.
The one thing I am unsure of is the burner plates where they meet the feed tube at the bottom. It seems there is a significant gap between the bottom of the burner plates and the feed tube. (See photo)
I used 5/8" diameter rope gasket. Everywhere else I used 3/8"

I could not find where it indicates what diameter rope gasket to use so I guessed and got what was local at the hardware store.

Should I perhaps fill the space with cement?
The plates are not cracked and some maybe slightly warped, but I was able to get the bottoms of the plates to form a circle without much effort.

There also is corrosion and pitting on the inside of the chamber. Is there anything I can do to prevent it? Is it just the nature of the beast? I have a chimney cap and run the stoker year round.

Thank you

I have used 5/8 gasket rope in that area, it worked fine for me.

Maybe it is just the picture, but that pot auger looks pretty worn.

Thanks for the reply Rob.
The auger is only a few years old. The flights are still smooth throughout.
I just cleaned out the back. I'll reinstall the baffles and fire it up.
Thanks again.

Nice fire!

I ran into the same problem with the bottom gasket. I ended up using 1/2", it was a little loose though. If I had some 5/8" I would have used that instead. I think this is caused by that area wearing. It should be a "U" channel that the gasket goes into but the inside is missing. So you use gasket to fill the gap. The two S-20 pots that I have are from about 1960 and they are both in the same shape down in there.
