Insert here. I usually start closing my primary in increments at or around 300-350. Don't know if your setup will allow, but I take my stove top temp with an IR gun pointed thru where the blower air exits.
I also have a Rutland Mag. Thermometer on my doors for reference (not accurate of stove top temps).
