An easier way to deal with "cold smoke" is to get a smoke generator like Todd's AMAZEN http://www.amazenproducts.com
stainless steel maze. Pretty inexpensive and lasts forever. If you like to play McGyver the dryer hose, etc. is very doable on an ECB. There is also the coffee can/soldering iron option. Good luck.
