First off, I have read the manual thoroughly, have done quite a bit of research online including this forum and was hoping someone with experience could clarify this for me. I am installing a Napoleon NPS40 Freestanding pellet stove. This will be a corner installation. The manual says not to use for than 180 degrees of bends and there is no EVL conversions. I am trying to follow the manual as precisely as possible but I have very few options for venting and placement. I would like to use the setup that is pictured. Can anyone tell me if this is satifies the 180 degree rule, I realize there is more than 180 degrees of turns but based on how I read the manual termination is not included in that value. Does the EVL 15 calculation apply to all pellet stoves? Also, does anyone have experience with this kit? It is simpson duravent so I assume it should be OK. Any help anyone can offer is greatly appreciated.
