I have an Englander 30 and I fear I may have overfired it. The paint around the collar looks a bit faded, almost rubbed away. I have never noticed the stove even remotely glowing, but my stovetop thermometer has been pegged at 800 before. This is my second year burning with the stove and I never had issues with the stove temps last year burning less than ideal wood(imagine that). Anyway, I have 30 feet of exterior Class A and my draft is a little extreme. Based upon some other members recommendations(thanks Pen) I installed the forbidden key damper last week. This has helped control the craziness but I noticed the paint around the collar missing at that time. I did a visual inspection at that time and it appeared superficial, but the bottom 12 inches of the black stove pipe is a bit lighter than the rest of the pipe--but still black. I have been burning for a week or two since that time and all seems good. I have a better grasp of my draft now with the damper and think it is under control. However, is the paint that is faded/gone a reason to shut it down and call someone? Anyway, forgive a newbie--I am learning as I go with this and hope I have this thing under control.
