I'd like to get a PE Alderlea which only comes with legs. I'm required to have an OAK (manufactured home) but the vent pipe may have to curve over to miss a floor joist. The stove location is very restricted due to ceiling and roof joists. What can I do to make this thing look decent, especially if I have to have a flex or angled pipe? I think the vent pipes are supposed to be 3" to meet requirements. A Super 27 is still a good option for us on a pedestal base, but I'd like to make an Alderlea work if possible.
