I can't find an appropriate thread to tag my question onto, so I'll start fresh.  I installed a BBQGuru DX2 controller system and tested (w/o meat) it today for the first time.  I'm using a New Braunfels Black Diamond (like a Hondo model) offset smoker.  I installed the blower in the lower portion of the firebox, under the charcoal/wood grate (as per the instructions).  It blows toward end the door of the FB, in the opposite direction from the cooking chamber.  I started a fire with a load of charcoal and then added some oak firewood, got it hot, and set the Guru for 275*.  I have installed a down-sloped baffle from the FB, as is recommended by many on this site.

The Guru maintained a perfectly steady 275* for about 3 1/2 - 4 hours, with the fan kicking on for short intervals (as designed and expected).  Then when the fuel supply began to be depleted, the CC temp dropped and the fan stayed on for longer periods (again, as expected).  All in all, the Guru appeared to control the CC temp dead on at 275* until it ran out of fuel.  I'm happy.

The only issue I noted was a coating of ash in the CC.  I've read it's not a problem, but would prefer not to have it in the CC.  So my question is whether I should slide (close) the air volume gate on the fan to reduce the volume of air and let the fan stay on for longer intervals.  Perhaps that would reduce the velocity of air through the FB and result in less ash in the CC.  The fan now maintains a clean strip along the bottom of the FB under the grate.  Maybe my fan is too large for this smoker.

I'm not sure which fan I have (three are offered).  My order confirmation reads [if gte mso 9]><xml> <w:WordDocument> <w:View>Normal</w:View> <w:Zoom>0</w:Zoom> <w:TrackMoves/> <w:TrackFormatting/>
