Hi Jay,
There are 2 differences between the Fogatti InstaShower 8 Pro RV Tankless Water Heater # FG47FR and 8 Plus # FG97FR. First being the # FG47FR has a 21.5 square inch mixing tank to help reduce the possibility of being scalded by super-heated water, while the # FG97FR does not.
The mixing tank on the # FG47FR therein adds a little depth to the heater and will measure 15-13/16” deep (the # FG97FR without the mixing tank measures 13-13/16”). The 13” width and height measurements are the same for both.
