Just got a p68, not set up yet. (New home that's not finished). New to this whole pellet stove thing and thought i'd come here for advice. It will be set up in my basement and it looks like i might have 3- 90 degree bends when it's all said and done. It either says in the manual 2- 90's or as few as possible (I forget which). If it is 3 will i be ok? Thanks
