Can someone please tell me what temperature I should run my vigilant at? It is an early 80's vigilant. Also, where should I take my temp reading? My pipe coming out of the stove in double wall interior stove pipe so I dont think I get an accurate reading from the stove pipe thermometer (due to the double wall). Normally if I have the stove thermometer on the top, right hand side of the stove I run about 500 or 550. Is that too hot? Also, sometimes the doors glow (very scary). This does not seem right to me. The doors will glow where the air comes into the stove (front, left, bottom) where the air is pulled in. I will check the stove in the middle of the night and they will be glowing. SCARY. Help me out boys.
