OK, so I have successfully scorched three batches of brew through my rims tube. It is only when I try to bring the mlt temp up due to a miscalculation. I went to the big orange box store today and purchased a camco 4500 watt ulwd element. I tried the 5500 watt version first and burnt my first batch with it. Thats when I decided to try the 4500 watt version. I have seen model numbers for a 02923 element. I got this one back to m work and couldn't help looking at it. The model number opposite the voltage and wattage rating says "camco 02922". I tried googling this model number and can't find anything on it. It says Ultra Low Watt Density on the package, but I am a little hesitant cuz I dont want to scorch another batch and waste more grain. I am using a rims tube made out of stainless 1.5" pipe yada yada. Whats up with the model #???
