I have a regency I2400 wood insert. I have been burning for about 3 years and I have a magnetic thermometer right on top of the stove. The thermometer has a burn zone of about 300 to 600. where should I be and how do you guys run your stoves. Should I get my stove up to lets say 650 and then back the damper way down? Or is there a better way to do it so my burn times are a little longer? I seem to reload about every hour and a half with another split of wood.. Is this normal?
