During the cook, just use the flue damper to increase or decrease the airflow through the smoker. If you find the smoker is getting too hot, just close the damper further. If you find the smoker is cooling down too much open the damper up and consider putting more wood in the firebox.
A big part of how open or closed your vents are is for temperature and burn control. The wider open your vents are, the more oxygen is fed to your fire, thus the fire burns hotter.
This chimney allows for proper ventilation of your smoker during the cook BUT it also plays a major role in temperature consistency. Having your smokestack open at all times allows the stale smoke to leave the smoker, rather than clinging to your meat, which causes that sour taste we all despise.

Intake Vent: It has one job – bring in oxygen to control the heat of the fire. If you need to raise the temperature of your unit, open the intake vent. Too much heat, close the intake vent which starves the fire for oxygen.
In this test (see bottom photo) I made sure to place a biscuit directly in front of the exhaust to show that in most smokers this is typically a hotter spot. As the heat is drawn closer to the exhaust, it is funneled into a smaller service area creating this hot spot.
The handle to open and close the damper should be above the fireplace opening. To open it, slide it to the right. To create fires that produce more heat, open the damper as wide as possible when lighting a fire. A wide-open damper will increase the amount of air reaching the fire and improve combustion.
You need to open the damper when you start a fire to allow for proper airflow and let the smoke out. A closed damper can restrict airflow and become a safety issue since smoke would fill your house.
A closed damper also stops cold drafts from coming down the chimney. When you are using your fireplace, it needs to be open so that smoke can vent outside. It also allows fresh air to come in to feed the fire.
You want to wait until at least 2/3rds of the charcoal lump has turned white and the charcoal has stopped smoking. You can use a charcoal grill tool to move the charcoal around so that it is evenly dispersed throughout the basin for even heating.
Pro Tip: Use the bottom rack for grilling and the top rack for smoking and baking 🔥 You'll get more direct heat from cooking on the bottom rack, and more indirect heat cooking on the top rack!
Check for any obstructions in the chimney, firebox, or vents and clean them. Use quality fuel to maximize heat output in your offset smoker. Check seals on offset smoker for deterioration and air leaks that disrupt airflow and heat efficiency. Replace worn-out seals to create a tight seal and retain heat.
If you discover that your smoker's internal temperature isn't reaching 220 degrees Fahrenheit, you can turn it up a notch by adding more charcoal or wood. Charcoal, of course, burns hotter than wood, so it can quickly and easily increase your smoker's temperature.
White smoke is usually produced when the fire is not burning hot enough or when using unseasoned wood. It contains more water vapor and larger particles, which can lead to a harsh, bitter flavor.
The open vents will draw smoke from the charcoal and wood below so that it swirls over your food and out the top properly, giving you the best ventilation and the cleanest smoke. If the fire gets too hot, close the top vent almost all the way.
Smoke damper's primary function is to control the movement of smoke in dynamic air distribution systems, and they reduce the possibility of smoke transfer within ductwork or through wall openings.
Primary Functions of a damper
Pressure Regulation: Dampers help regulate the pressure within a duct or pipeline by adjusting the cross-sectional area through which the fluid passes. This can therefore be crucial in maintaining a stable and controlled pressure in various industrial processes.
Increasing airflow produces more vapour but doesn't change the amount of e-liquid used. Your nicotine intake remains the same unless you improperly draw the diluted vapour.
Always keep your smoker vents open to ensure optimal temperature control, smoke management, and air circulation.
Remember that closing this vent too much or too quickly can drop the temperature and even kill the flames. It's important to close the vent only in small increments and slowly re-open it if you sense the temperature dying down.
