Product review (5 stars): Layout and other associated parts that may be required.
This unit was a bit complicated to install in my situation because of the in-wall vent pipe.  It was installed at an odd angle and a standard 90 elbow put the vent pipe too far into the room.  After getting an offset 90 that kept the vent pipe closer to the wall, it all came together just fine.  The magnetic attachment was clean and simple to get connected.  Great product.
