No soffit? PM390/357NDK
Hello, I purchased the PM390 power pack and the 357NDK non-duct kit to go in my custom cabinetry, which has an LT30 liner. I need this to vent straight up, instead of up and to the side, as there are cabinets on all sides with an opening at the top. I do not have a soffit. Can I bypass using the L shaped duct piece? If so, should I put anything over the cylinder duct? Will I have issues with my ceiling? If this won't work, what do you recommend? Any help would be much appreciated.
