According to my research your Girard GSWH-2 tankless water heater measures 12-1/2" wide x 12-1/2" tall x 15-1/2" deep and the Furrion RV Tankless Water Heater # FR68SR measures 12-5/8" wide x 12-5/8" tall x 19-1/4" deep so as long as you have a little more depth for the Furrion this will work well as a replacement!
