Calling all Fireview owners. Seems there is some variations on flue temps out there. Was wondering if everyone could chime in and give their temps whether external, internal and where abouts the readings are taken from. With a full load of hardwood my internal temps (condar flue probe) at about 20" above the exhaust collar runs anywhere from 500-700. With an external magnetic thermometer it reads 200-400. Where are use guys and gals at?
