oldspark said:Pen, I find it interesting that your stack temp is higher than stove top in every case, it seems like most people report just the opposite except for reload and start up, do you ever have fires where the stove top is hotter than the stack temp? I like your drawings as it makes it easy for an idiot (me) to understand.
If I had a magnetic thermometer on there then you would be right. A probe thermometer measures internal temperature which is much hotter than the stove pipe itself.
