Should I leave the vent open on my smoker?
Regarding this, should I leave the vent open on my electric smoker?
As a rule of thumb, it is best to leave the vent fully open while you are applying smoke to your meat. By leaving the vent completely open, you avoid the risk of creosote building up on your meat.
In this regard, when smoking meat do you leave the vent open?
If the upper vent is fully closed, the fire will die. If I need to get higher temps, lower vent needs to be open (e.g about a square inch of area), so does the chimney (about a couple square inches of area) - this'll stabilize about 350F. Smoke "sticks" to moisture.
Because hot air rises, your exhaust vent acts as a vacuum to draw air into the intake vent. When this hot air rises, it heats up your smoker. The exhaust damper (a.k.a. flue, vent, or chimney) has two jobs: (1) Allow the combustion gases, heat, and smoke to escape, and (2) pull oxygen in through the intake damper.
