I started out with a 20”x66” CDL drop flue evaporator with 1 float box and hated it. Mainly because if you had a fairly big draw of syrup, rear mounted float box did not respond fast enough to keep from burning in the front pan. Also, mine did not have a drain in the drop flue pan and it stunk trying to get all the sap out to take the pan off to clean it. I had to use a little hand pump to suck it out. My advice would be to seriously consider going to a raised flue pan evaporator. I don’t know how many taps you have but it might be worth considering a 2x6 raised flue.
