Received with a corner bent due to shipping. Does not come with installation screws. Unit was not difficult to install but the gas line was difficult to get lined up. Comes with a plug in for electricity so will need to run an outlet for 110. Used PEX pipe and fittings for the water lines.


Comments
Customer Service will reach out about the bent corner.

Ask the Experts about this Dometic RV Water Heaters

  • Atwood GC6AA-10E Replacement Recommendation
    You can install a larger tank but that is all based on the space you have in your camper/RV and whether or not you're willing to possibly cut a bigger cutout hole in the wall of your camper/RV. An in stock alternative to the # DMC74FR would be the Furrion RV Tankless Water Heater - Gas - Automatic Pilot - 60,000 BTU Item # FR93FR. It has similar dimensions and can offer a a higher gallon output per hour at a similar cost.

  • Atwood GCH6AA-10E Replacement
    It is possible that we have old answers that point to products we no longer carry but I do have a solution for you. Recently Dometic bought Atwood, and has been discontinuing most of the Atwood branded product, including the GCH6AA-10E. The only replacement for your Atwood is the Dometic # DMC74FR. Like your Atwood, it is 6 gallons, and runs on propane or electric, and has an automatic pilot. Because it is a little smaller in size you will need the Dometic # DMC84FR kit that includes...

  • Replacement for Atwood G6A-8E 6 gallon Water Heater
    Yes, if you want a 6-gallon gas/electric water heater then the Atwood # DMC74FR is the only choice. You should know that it is more like 20" deep, and its width and height is smaller so you will need the # DMC84FR door conversion kit to help fit it to the old opening. Your installer will use a few common hardware store fittings when installing the new heater.

  • Replacement RV Water Heater for the Atwood GC6AA-10E
    The correct replacement for your Atwood water heater is going to be the Dometic RV Water Heater # DMC74FR. Like your Atwood this is a 6 gallon water heater.

  • Water Heater To Replace Atwood Gc6aa/10E
    The direct replacement for your Atwood Gc6aa/10E water heater has been discontinued. I recommend the Atwood RV Water Heater Item # DMC74FR which only requires a 12-3/4" x 12-3/4" cutout. This is a standard gas and electric, 10,000 BTU water heater which recovers up to 12 gallons of water per hour. Your current Atwood requires a 16" x 12-1/2" cutout. Since the new Atwood cutout is smaller, I recommend using the Water Heater Door Conversion Kit Item # DMC84FR. It is also available in black...

  • Correct Replacement for Atwood G6A8E Water Heater
    The correct replacement for an Atwood G6A8E Water Heater has been discontinued. That said, we do still have a replacement option. The Atwood RV Water Heater part # DMC74FR will work as a replacement but the cutout for the unit will be larger than needed and you'll have to run electric to the unit since this one is gas/electric and the one you have now is gas only. In regards to the larger cutout, this can be filled with the Water Heater Door Conversion Kit part # DMC24FR or part # DMC84FR.

  • Recommended Water Heater To Replace Atwood GC 6AA-10E
    You have the parts needed right on the money. To replace your Atwood GC 6AA-10E you will indeed need the Dometic # DMC74FR you were looking at, and since it fits an RV cutout that is a bit smaller you will indeed need the Water Heater Door Conversion Kit # DMC84FR. Lastly you will need to have professional install the water heater. I included videos of the products mentioned for you to take a look at.

The discontinued water heater you have had an aluminum 6 gallon tank and manual ignition. Most any water heater will fit in the area of your old water heater.

If this is not abided then warranty will most likely be voided. Since you will be using this as a replacement, not a new install, the current switches...
