newbie here with the same smoker - Great post to help me get started.. Doing my first smoke this morning and it has been 'trying' to say the least. I have a few questions
Background - First smoker, before I used indirect heat on a weber gas grill. I am using pea gravel in the water tray and smoking a smaller boston butt (3.5#). All vents are closed as far as possible. i do have a piece of reflectix around the smoker since we always have a decent wind and when i seasoned it temps would jump around horribly with every breeze. I am on the side of the house with the least wind as well.
Your upper (exhaust) vent should be full open to create enough draft for the smoker to have reduced grate temp variances from bottom to top. Also, this keeps stagnant smoke from building up inside the cabinet. If you have a door thermometer reading a lot less than grate temps near the middle of the smoker, than either the thermometer is not accurate or you have too little draft in the cabinet. The door therm should be reading a bit higher than the grate temps are, most of the time...of course nasty weather can cause a lower cabinet temp, too...my
WSM lid therm drops a lot in the wind, but grate temps don't drop nearly as much.
Thermometers - I have a
Thermoworks DOT clipped on the cooking rack im using as my bench mark. A new Tru-Tel thermometer is in the door its barely showing 175, when im getting 225 inside. For giggles I put the old door thermometer in the top vent and its reading closer to the DOT, but not exact.
1) IF i wanted to use the DOT inside the meat, any reason to not use a thermometer in the top vent to keep an eye inside temps? (knowing its close but not perfect). The door thermometer appears to be useless
The door therm can be calibrated to a verified digital thermometer as well...7/16" end-wrench, if I recall. I used to monitor with a long-stem fryer therm in the top before I had enough digital units to go around...what ever you have on hand can be put to use.
Temps finally stabilized at about 225 for about 1.5 hrs then jumped to 245.. flame is nice and blue and the knob is as lowest as it would go and it was still in the 240s.. I opened the top vent fully and the temps dropped to 235 and seem to be stabilized.. I also tried closing the valve on the propane tank and that had no effect on temps
Propane tank valve should always be fully opened or fully closed...not designed to seal the valve stem from leakage if partially opened...the valves can't throttle-back to that low of a flow, anyway. If you push the valve in and turn towards the "warm" setting, you will notice the flame begin to diminish. Use that to reduce your chamber temps, if needed...that's what it is designed for. It's just a safety net to keep you from turning it too low and the flame going out without you having to use a bit of caution before you dial it back that far. On mine, in cooler weather, it will run at about 175* or lower without selecting the low-flame settings on warm.
2) Should i worry about getting any lower than 235 on a 54* day here in Virginia
Shouldn't be an issue...stanmdard low & slow temp for larger cuts of beef and pork is 225*...I have run a bit lower, but you should start around 225* or higher, just for the sake of pasteurizing the surface of the meat.
3) The control knob is at its lowest setting - but the indicator is between MED and LOW - is it suppose to match up?
Probably just a minor manufacturing or assembly defect...nothing to worry about, though.
4) What is the 'warm' setting for on the knob?
(explained above)
Thanks
