My magnetic pipe thermometer is 13" above the stove top just below the damper on single wall pipe , running at 350 on that thermometer, which is correct , the stove top (directly on top) is 650 , towards the back on the top, temp is higher, my IR thermometer only goes to 700. I have ordered a Condar magnetic stovetop thermometer so I can monitor that better. Now that I have explained that, I will ask the questions I have read people say, to run a stove at 500 to 650 degrees, stove top temp . Now If I run my stove at 400 on the pipe burn indicator, which is about the middle of the burn zone, the stove top is going to be IDK for sure ,but probably 750 or 800. So, am I running it to hot ? According to the zones on the pipe thermometer 275 is the lowest U should run , is that about right? A thermometer measures the temperaturet, so ,how in hell, can a pipe, or stove top thermometer be any different ?
