The wife and I want to get a fireplace well two of them one for our living room the other for are bed room . Don't know much about fireplaces but I think this will be a DIY anyway what is the difference between vented and non vented ? I'm assuming that non vented means no chimney ? And the only reason I'm leaning towards gas is because my house is plumbed for gas . Still thinking about a good ol wood burner though . The ones I'm looking at are just the steel box type and I would frame around them and Sheetrock them in and add a mantle thanks for the help .
