How can i stop creosote build up in my stainless steel liner in brick chimney? Run fire hot and damper open?

Question

Wood stove is state of the art and works fantastic but only for about a month at a time then the chimney liner plugs up near top with major creosote build up....burning well seasoned chery damper fully open cant figure this one out...i have never had the prob before from other experiences

What is "vermiculate" ? is it like a cement that pours around the outside of liner between that and chimney? Can it ever be removed if the liner needs to be replcaed ?

Answer 1

Switch to hardwoods such as seasoned oak.

Answer 2

Brickey is correct, you either have to burn the fire a bit hotter or insulate the pipe. I used to have a graph that showed stack temp vs. buildup. Bottom line, as the gases cool in the chimney they precipitate the particulates out onto the cooler pipe. We used to open a door or window and run the stove a bit hotter in warmer weather.

Answer 3

what do you have between the liner and the brick?...sounds like your chimney is too cold toward the top...if possible fill the space between the liner and chimney with vermiculite and your stack may stay hot the entire length...vermiculite is a granular fill that comes in big bags...you would need to pour it in from the top...make sure its not running out any holes down below...will have to stuff something around pipe above your clean-out door if you have one...
