I have just purchased a Lopi Endeavor stove and I already have my ceiling kit and triple wall pipe installed going out of the roof. The next step is purchasing and installing my double wall stove pipe and here is my question. Do I need an adapter to connect the pipe to the top of the stove? As well as an adapter to connect the pipe to the ceiling box? I'm considering buying Selkirk double wall pipe from Lowes but I want to be 100 percent sure of what exactly I need before I buy it. Any information would be much appreciated!
