I have purchased a Mt. Vernon AE and it is being installed in a few weeks. Was wondering if any of you 'experts' out there have an opinion on how we should vent this thing. My wife, for aesthetics, wants it to go out behind the stove, then rise on the outside of the house. I have heard that it is better to have the rise inside. Any suggestions would be appreciated! By the way, pellet issues here in Central PA are not very significant- we can get as much as we want for $195/ton as of now- but we have a few manufacturers very close by. Hope the rest of you can find your supply, I'm looking forward to my first pellet heated winter!
