set up is a wsm 22.5 guru dxII, bottom vents closed, top vent was 2 probes wide lets say 1/4" outside temp 24 degrees Now was first time use for a atc. everything fine took about an hour and fifteen to get to temps 225 minion start full ring k blue 15 briquets hot into center 6 chunks apple mixed throughout. two shoulders on 1 gal water in foiled pan.( usually dry foiled only) read about blower output by counting the warble. stayed at 7 blips 70%. meat went on around 7:40 and it is now 9:02 so thirteen hours plus very steady temps is it because of the outside temps that the blower runs at such a higher rate or is the unit working as it should. grill is pretty tight i modded door with hammer and dolly and seals well.from what i read things seem good but i have found posts of this set up with similliar outside ambient temps and blower output was much lower opened door fifteen min ago plenty of fuel left and burning even.
