According to the manual "Smoke setting on the thermostat will operate the oven at approximately 180* to 200*. (This setting provides fuel to the burner at the ratio of 15 seconds on and 55 seconds off.)"
With my FE, during the winter the smoke setting is at 130*. In the summer, the smoke setting jumps to 200*. Higher temps are always constant, winter or summer. My pit is out side all the time. (There is a roof over it.) I never empty the hopper. The rain and dampness have not affected it's performance. I have no problems starting up on the smoke setting, or starting at 325* or higher. It always ignites.
