When you hooked up the black + and the White - wire. What did they go to on the trailer side? Black + and orange? White with blue?

Well, I was merely looking for the 12V circuit for control power, there's not a lot of load on that circuit. I used a multi-meter to locate those wires. I would anticipate the colors on every RV are unique. I re-utilized the 120V power for another GFCI outlet in the bathroom, you don't need that. The original Atwood had 12V power for the control circuit only, to "enable" the water heater, essentially the gas side of your water heater. The electric side of the hot water heater is "enabled" by 12V too, the other switch. It merely turns on a relay to provide the 120 volts when you are running electric. This is the way mine was wired...hope that helps.

I will say that Furrion I've heard is doing some kind of redesign on that water heater...I don't have many details, but, it appears that when the unit is not fully flushed and or drained for winterizing the water mix tank can get damaged from freezing. I don't have to winterize mine, it's stored inside, but just FYSA.

We were hoping to see how you did the wiring. We took out and are putting in the same units you did. However, the lines that we have running from the preexisting unit are green, brown and blue. So we don't know how those three connect to the black and white wires on the new unit.

Hi Luana, you know, ever single unit is different and it wired somewhat differently. It also varies based on the manufacturer. The black and white wires on the unit itself are for 12 volt power. I would recommend that you use a multimeter and check the green, brown and blue wires in your RV and determine which of those wires have switched 12 volt power. I would also recommend that you attach some type of 12 volt device to that circuit and make sure that you still have power when you apply a load to the circuit. This is something that I disovered while installing my On Demand hot water heater. The DSI circuit is part of a safety feature of most factory gas/electric 6 gallon hot water heaters and if you drop 12 volt power when you apply a load to that circuit, you MIGHT need to make the additional change in the control panel I talk about in my videos. However, if you still have 12 volt power after you put a load on that circuit you should be fine. Like I said, all the RVs are different, I hope my advice was helpful.

Did you run new 12v power to the tankless?

Thanks for the comment, I find them very entertaining and useful. No, I didn't run new 12 volt DC to the new hot water heater I used the original gas hot water heater circuit. But, you could just run a new circuit and eliminate the need to disable the DSI circuit. I did disabled the DSI circuit per my video in the RV control panel. The way that circuit works is that is looks for a ground from the original RV Atwood control unit. If you had an Atwood 6 gallon like myself, you will need to disable that DSI circuit by making your ground at the control panel per my video.

@@RocketCityRVer I had a problem when installing my Girard tankless water heater. When I wired it to the old switch for my suburban water heater a red light would always stay on and it was really annoying to me. So I just ran myself some new leads since it was right next to the anyways
