Something i also noticed when i got my first 55 is the clean smoke that the CS's make can be hard to see, its not like most other smokers i used. Take a good smell and see if you smell the smoke. Early on i thought i had the same problem so i put a green piece of wood in the smoke box and wow you could see that coming out but thats the impurities that you see thats what you dont want on your meat. Try putting a piece of meat in there and taste the smoke flavor it produces. This is the best smoker i have ever used i loved it so much after just 2 months i bought a fec100. Just through you some meat in there and enjoy.
