I know there has been a number of questions on this board about thermometer placement, but I couldn't find the answer to my question. My stove is a new Regency F2400 and I'm getting lower temps on the single wall pipe than the actual stove top. (300-475 10" or so on the pipe vs 450-500+ on the stove top. (I think my wood is wet)) I haven't tried to test it on the door front. Which is the correct placement for this stove?
