I have the Regency Hi500. I am interested in the Sooteater, but how does one access the flue from the bottom? I do not see any access to the flue, unless I would image disconnecting the entire unit, but at 500 pounds, I am not going to be moving it. Going from the top down, all the junk it removes is just going to sit at the bottom of the flue on top of the bypass, right? Am I missing something?
