Even a couple hours after i shake the stove i try to open vents nd as soon as i do i have blue flames going up that pipe again. I am just so confused. Never had so much trouble with this stove. At this point I'm thinking of letting it go out and just starting over. does white ash burn hotter or red ash? I just dont even know where to begin.
Whoa slow down lol don't panic
Overdraft just means its getting too much combustion air due too a combination of a strong pulling chimney AND combustion air vents being opened too far.. You said as soon as you open the vents you see more blue flames.. Recently right? During this colder than normal weather? It seems to me that your chimney is drafting stronger and again, I think your fire is just getting overdrafted because of this.. Are you just swinging the vents wide open? These vents allow air to come in over the fire right? This condition with fresh coal would justify the big blues. Did you try gradually opening the vents? See, I think your in the dark a little since I assume you don't have a manometer installed. You don't know how much stronger that chimney is pulling when its this cold out. I also think that there is merit to the suggestions the Rev made regarding the gaskets, since that would add to the overdrafting I think is happening compiled with the colder weather and the stronger drawing chimney....
I wouldn't pursue the red ash vrs. white ash thing for the issue you are having right now..
