Hello Rick,
When I look up the dimensions for the G6A-7 it is listed as 12 3/4" x 12 3/4", the Replacement Fogatti InstaShower 7 Tankless Water Heater - 48,000 Btu # FG37FR is actually 13" x 13". Also, since this is a tankless water heater it is 13-13/16" deep, instead of the 19 3/16" like the one you are replacing. This water heater will still be your best replacement.
The door is not included with the # FG37FR, so you will instead want the # FG56FR for the white 15"x18" door, or # FG36FR for the black 15'x18" door.
Any big trips coming up? If so, where are you headed?
