Hey guys I just got my new model 18 last night. The install went pretty good. The only problem I have is the stove won't draw. With the primary air open and the door closed the fire just goes out. You can see the smoke just keep gathering up inside the stove. When I open the door the smoke just clears right out. The dealer who ordered it for me said it did not need have to have a pipe from the stove to the flu pipe. It is only about 6 inches apart and it is a prefab fireplace in a doublewide. The smoke has nowhere to go but up. The flue is 8 inches and the stove collar is six inches. Also by the time I put the stove back in the fireplace the flue pipe and the stove collar is about a half a hole off. Do I need some kind of pipe or connector? It seems like it is gonna heat really well. I never had this problem when I burned wood last year in the fireplace. any help would be greatly appreciated.
