Moved into this house with a propane fireplace and have realized that the blower I just ordered on line is going back because this thing has RIPPED through propane. Want to go to a pellet job. The propane exhausts through the wall next to the fireplace through a double pipe (exhaust/inside and intake/outside). Can I direct exhaust a pellet fireplace through the wall. Haven't done the research, just thought some of the subscribers would have some quick, witty, intelligent, answers as they typically do. Thanks in advance.
