I don’t think I burned enough wood to make a significant difference, ( I’m pretty sure you need high sulfur and repeated high humidity/condensation to start to etch it)waytomany?s wrote: ↑Thu. Mar. 02, 2023 7:17 pmJust coal, or did you do like others mentioned about burning wood and getting some creosote in it first?
King Oak 19B never used, should I use it?

Small low fire the first time and let it go out. That'll cure the cast iron some.
Its really hit and miss with stainless liners but for sure I'd burn wood for a while first to get a good coating in whatever chimney you set it up with. Dont do clean burns, make some smoke to coat the chimney. im not talking about an inch of creosote, just a coating. others have used various oils and voodoo witchcraft to save on the steel. Plenty to read about on the forum with that issue.
Keep a pail of sand or ash to throw on the fire while learning your stove in case you need to put it out for whatever reason.

I spoke to Dura Vent today. I asked what SS # was in their double wall elbows and straight pipe and if okay to burn coal. They said yes coal can be burned, it’s 430 SS and has a 5 year warranty.

Use the search function on this thread.
Some have had stainless steel liners last, some haven’t.
Plenty of pictures to support both.
Plenty of people had stainless steel rot out in less than 5 years…and I mean totally rotted. Some, it didn’t matter if it was cleaned or not.
Many other companies, like Rockford Chimney supply, recommend 316Ti, as it is rated for coal and has a high temperature rating…although coal doesn’t necessarily run at such high temperature exhaust unless someone forgets and leaves a lower vent open too much. From what I’ve read here the 316Ti has a better corrosion resistance than regular 316 or 304.
One member here, since coal stoves run at such low temperatures, decided to go a different route and opted for the liner that doesn’t have the highest heat rating, but does have the highest corrosion resistance, AL 29-4C, and he swears by it. It is expensive though. It’s also rated for gas furnaces. Can’t recall his user name but I think his name is Scott. He swears AL 29-4C is the best stainless liner for corrosion resistance, and I tend to think he’s on to something since experiencing my own low temperature exhaust from my coal stove. It has run nowhere near the exhaust temperatures of wood with the same stove, not even close…the wood has way hotter exhaust than the coal.
Freetown Fred knows who I’m referring asking about. Scott burns an old antique or two. Help me out, Fred!
