Ok so I have been playing with temp controls while the new smoker is seasoning. With all the vents open wide and the selector on low, I am at about 210 with OAT at about 60. Now am I correct in thinking that with Propane (constant BTU output with selected flow) the vents just control air flow. more air = lower temps? I can now see why people convert the wood box. It doesn't put out much if any smoke at this temp with the stock box. If you use the wood shreds instead of chips will it work until I get the box modified? I did "calibrate" the stock temp gauge with boiling water. Have to wait until my ET-73 shows up in the mail before I can get exact temps. No one around here seems to carry them.
