Kyle_A - Eight hours to smoke salmon in a Luhr Jensen smoker (Big Chief/Little Chief) is normal; but it depends on the outside temperature, the wind, and the thickness of your fillets. Under ideal conditions (above 60F and no wind), eight hours is about right for average sized salmon fillets. But if it's cold, windy, or the fillets are quite thick, it could take alot more time.

Brinkman smokers run at a much higher temperature and tend to roast your salmon rather than smoke it. I use a Big Chief for salmon and my Brinkman for chicken, pork, sausage, etc. Good luck
