There are lots of threads on this site about fire management in an offset smoker. Most are several years old and probably buried and forgotten in the ashes from years of smoking. I thought I'd add my recent thoughts and experience with my offset. I'm getting ready to cook my first brisket on July 4 and have been practicing fire management in preparation for that. I'm using a New Braunfels Black Diamond, but I think my observations apply to any of the similar offsets. I made the recommended mods to the smoker and after numerous trial runs (no meat) I've come to the following conclusions.
Sealing up the smoker
Do it. Do some test burns and observe where any smoke leaks are. I used a fair amount of fiberglass tape and high temp silicone to seal both the doors. My smoker won't float, but it's pretty tight. Many offsets can leak a lot and that means heat loss and lack of air control.
Getting it up to temperature
At first, I was having a difficult time getting mine up to 275*, my target temp, using a chimney of lit charcoal. It took about two hours. Turns out, I wasn’t giving it nearly enough fuel. Today, I dumped a chimney of lit coals into the firebox and then added two more (unlit) and in about 20-25 minutes it was up to 300*. Solution: Give it plenty of fuel.
Temperature control
I admit to using a BBQGuru to control the fire. There are other systems that do the same thing. I know it's frowned on by the purists, but I drive a car with an automatic transmission too. During a cook with guests coming over and sides to prepare, I don’t want to have to tweak the fire every 15-30 minutes during a 10-12 hour cook. So I bought and use the Guru and it works as advertised, maintaining the temp that I set it for. As long as there is enough fuel in the firebox, it controls the temp to within a degree of the setting.
Heat and smoke
My theory is that heat comes from charcoal and smoke/flavor from wood. I found that trying to maintain the desired temp with wood and at the same time produce thin blue smoke was next to impossible. The wood produced billowing clouds of thick smoke while maintaining the temp. Overpowering smoke is not good for flavor. Now I use a full box of charcoal for heat and throw in a piece of wood for smoke, like maybe 2"x3"x8". Nice thin smoke from this and after an hour or so (if needed), I throw in another chunk of wood.
So those are my comments. In summary:
Seal the smoker well
Give it adequate fuel
Use a temperature control system
Get your heat from charcoal and smoke/flavor from wood chunks
Hope this helps.
