I keep reading about flame height not being too tall. My stove flame changes constantly. Sometimes about 3 to 4 inches above the burnpot, other times it is hitting the top of the firebox. To get started yesterday I had to crank the damper way open. It seemed to burn fine except the constantly changing flame size. This morning I closed the damper almost all the way and nothing has really changed. Does anyone have any input on this one? I have my first child on the way here in a couple of months and the last thing I want is a fire hazard with a newborn in the house.
