Just got mine delivered yesterday. 18" version. I'm working out of a MES 40. Also got 2 5lb bags of pellets from them (apple and pecan) After reading the instructions and poking around a bit, I have a couple of questions. First is how do you fill it if you don't want the full time? Do you stuff some tin foil in there and just fill it like 6 inches if you only want two or three hours? Or do you fill the whole thing and pour out the burning part when done? Second has to do with the MES. I see some people here pull out the loader to get air flow, is that really necessary or just if you're having trouble keeping it lit? It's really windy here all the time so I think that might be too much, but I'm not sure. Any other advice on this before I use it?
