Just bought a big frontload homemade electric smoker. Woman said her husband produced the best smoked salmon from it. I'm having trouble learning how to get the temp up past 180. It has an adjustable hot plate at the bottom with an adjustable fan also attached. adjustable drafts are at the top and bottom of the smoker. Do I keep the fan off and the drafts closed to get the temp up or fan on high or ? ? ? Your thoughts and suggestions greatly appreciated.
