Just wondering if you need a special cap for burning coal. I'm using the existing class a that was already installed in the house for the wood stove that I now replaced with my stoker. I have one similar to this

I would not bother with a cap unless you are having downdraft issues. $80 will buy a lot of coal.

Cap will keep out rain/snow, etc. and help prevent corrosion inside the chimney. Coal ash has sulfur in it. Sulfur + water = sulfuric acid = rot out metal.

Cap can also collect ash, etc. and clog if not maintained, but MUCH worse if burning bituminous. That can clog a cap in a day or two.

Doesnt sound good. So there isnt much you can do just keep an eye on it. I saw this cap listed on another site and it said you cant use it with coal thats why I asked.. I do get some down draft sometimes if it is extremely windy out but im assuming thats normal.
