TSB, is 350 - 450 for a forced air stove? He's burning in a Vigilant II that's totally radiant. Paraphrasing from what I recall from the manual, the Vigilant should operate 400 -700. That's taking a measurement right from the top of the cast top loading door that sits directly above the fire.
Be careful of what tools you use to measure with. I've had three different magnetic stove top thermometers that calibrated ok when suspended in boiling water. They all read differently when on the stove top. Trying to be more accurate, I bought an IR thermometer. It agrees with other calibrated thermometers I've checked it against. When my stove is burning at 700, the max recommended, I'm putting 85-90 Lbs of pea thru it a day. According to other calculations I've gleaned from this forum, that works out to close to 50,000 btu/hr - max output for the Vigilant.
