you should consider cutting off the excess soft copper gas line. You can get a flexible (accordion-style) section to go between the stub of copper tubing and the heater. The flex line will withstand bending and vibration better than the tubing will.

I remember when I installed my nest thermostat in my 1976 holiday rambler imperial 5000, it didn't work at first because my camper had a 3-wire system and the nest thermostat required 4 I believe the wire was blue on the thermostat and I needed an ac wall plug with a certain voltage to power that blue wire. They called it a C wire. since I put power to that blue wire my nest thermostat works great maybe that blue wire on your tankless water heater is there for older campers with a 3 wire format. I have yet to install my fogotti tankless water heater that I purchased last season because it is winter where I live. I'm sure once spring gets hear I will install it and see if I need to use that blue wire..
The BLUE wire is connected to the original water heater switch and must be a relay/ground that makes the switch usable. I also had a GREEN wire that served as a ground to the original water heater. I wired them BOTH to the NEG wire of the 12v power duo. The original switch now works as an interior power switch to the unit, the controller for the new unit works now, and the system is working!
I installed this same water heater in my motorhome, over a year ago and it works great the best feature for me is I can set the hot water temperature on the control itself for when I shower. That way I don't have to deal with pressure changes since I am hooked up to a well.
Accidentally disliked it but put thumbs up right now, this video is awesome, good honest review would love to see even a 1 month update I just purchased my first unit, the same one you have and I’m hoping most of the bad reviews on Amazon are from people that are just not understanding how to wire it also, super helpful!!
I'm very glad you liked the video. I will be using the RV a fair amount this summer so I will have more videos and updates. I will also be installing a 120v Mini Split to replace the ceiling mounted AC.
Thanks for posting this, it helped point me in the right direction...I had to do my wiring a little different, but I got it working. I live in my rv full time, and had this current one for about 3 years...first time in any rv or trailer that I've been able to take a hot shower longer than 5 minutes 🤣 I should have done this a long time ago haha
In your case you no longer need the bypass line. There’s no way to drain the water. Therefore: you will fill your heater with antifreeze in order to winterize. Also, these units require a pressure relief valve to be installed on the outlet side.
It seems the pressure relief valve is built in as per the product description: "Fogatti has always thought of you, with a pressure relief valve built into the product, so you don't have to buy and install it separately." Regarding winterizing, you are correct. I have a three way valve in my RV at the outlet the the water pump to bypass the main water holding tank inlet. I connect a hose from that into RV antifreeze container, turn on the water pump which then pumps antifreeze throughout the RV water lines. Water taps are opened one at a time until anti-freeze flows out, replacing water in the lines, closed for the next one to open, then all taps are left open for the winter. The water pump, by its pumping anti-freeze will also then be winterized. Three way valves should be readily available at local RV shops, or Amazon. As an aside, I have a tankless water heater in my summer cabin for which the same winterizing is used and has been perfect for at least 15 years of northern Canadian winters.
@@CampHikeSki My experience in Northern Canada, Yukon Territory, winterizing our 5th wheel trailer and researching the topic before hand.....definitely leave all taps open. I do the same with my cabin that is plumbed with an RV 12V water pump from a fresh water holding tank. Here's the logic. I can, but don't drain the water from the line in the cabin but I do in the 5th wheel as there are drains for which I crawl under the trailer and open them to drain, then close them before pumping in antifreeze. Next I operate the three way valve to bypass the fresh water tank(s) which I've drained and put a hose into the container of antifreeze and turn on the pump. All taps are closed at this point. I start with the taps furthest away from the antifreeze so it's getting pumped through the system. I start with either the hot or cold circuit, but do all cold or all hot then switch. I open the first, once a good flow on antifreeze comes out I close the tap then move onto the next tap, open, flow, then close and so on until, for example all hot is done, then move onto the cold. Once the other side of the taps are done, including the tub shower, which I leave the shower head hanging down to drain, I open all taps. Here's your question: Why - any antifreeze, yes, will drain, but then only air is left. No chance of freezing. The pump is the last thing and is will be full of antifreeze and yes, I leave the tap open which was pumping antifreeze from the source container. Air, antifreeze but no water to freeze and break taps or pipes. Frozen water is evil! Expanding ice has cracked 2 inch diameter water pump fittings that I left closed which contained water left in the 2" ball valve. Air, antifreeze. Leave the taps open is my method. Up to you I guess, but get all the water out! Others blow air through their systems to clear out water, but only if there's a definite drain(s) in the lowest possible area. I've had success with my method so continue to use it.
Haha ya it didn't feel good smashing my thumb. I figured out how to drain the tankless water heater for winter as well. You need a long skinny flat head screw driver. there is a small tube to the bottom right of the water heater that you stick that into and turn counter clockwise and it will drain the whole tank. Then you can fill it with RV winterizing fluid.
The BLUE wire is connected to the original water heater switch and must be a relay/ground that makes the switch usable. I also had a GREEN wire that served as a ground to the original water heater.

@@gregfisher5191what if my camper has propane only water heater and I don’t have a wall switch? Would I just cap that wire off? Or wire to the 12v power ?
I just ordered one...curious, will a 1/2 inch female to pex sharkbite work for the hot and cold water connections? I have to redo most my piping for this install. Update: it does 😄
Thank you for this!! This is soooo helpful! Did you get the Back flow or pressure relief with your unit?? Or just buy it how it comes with the tape and screws?
@@minutemanprep I saw one guy put one in with supplies he bought from Home Depot. He seemed to think that it’s a must have for safety and maybe he’s right. However in my case I’d have to drill a hole in the floor to give the water somewhere to go and I’d really rather not.
@@minutemanprep in the manual it does say it requires a relief valve but it isn't provided with the tank. Editing to add- in fact, it also states on the top of the unit "T&P Drain Valve Operation Instructions" on how you need to check the relief valve yearly.

@@ashleyhead2617 I'll have to check it again, not sure how I missed that. mine came with a relief valve but didn't see anywhere to add it. I am about to pull out my RV from winter storage and do more upgrades like installing a mini split in it and do more week long trips. Thanks for letting me know.
Hi Fogatti, can you send your contact info? I had one installed and it does not work at all. Had second tech company inspect it and they couldn't get it to work either. 800.00 unit plus 5 hours labour and still not working.
I need to make one. But to winterize it you take a long flat head screw driver and put it up the small tube that is located on the bottom right of the heater and turn counter clockwise to drain it. Then fill your RV with RV antifreeze, run the pumps including the hot water system, and then when you see the pink fluid coming out you know it's filled and you close up the drain.
Quick, but maybe a real dumb question, I'm going to go off grid in a small house and wanted to know if I can use this tankless heater system for my hot water usage...? 😬, remember, i said that it was a dumb question...
I just ordered this water heater, however I do not really have a fancy electrical system. All my lights, waterpump and sound system are wired straight to my solar batteries. I live off grid. Am I able to just run the red and black wires directly to the battery terminals? If so which is the positive? The red wire?

I have the same system that I recently installed in a shuttle bus conversion. Mine is getting water in from the vent that is going inside the unit, and then leaking into the bus from the metal seams around the outside of the box. Has anyone experienced this problem? It isn't leaking around where it is caulked around the outside.
Was there any rime or reason to wiring the controller? I'm not getting power to my controller, but the positive wires to the unit have voltage going through them and the negative wires are hooked up correctly
@@minutemanprep I was looking how to install this, and replacing a suburban water heater as well. Mine actually had the 110v hookup on the other side so I was even more confused. From what I can see on the wiring diagram the blue wire goes to a light in the old unit. Great video btw. Clear presentation and view.

@gregfisher5191 we are not electricians, do you mean switch/Toggle inside the rv that would turn on the old tank? And you mean the green and the blue to the negative? I have a green, orange white and blue bundle. So can you explain what you connected to what exactly
You are hooking to the black and white 120v ac, there should have been a second set of wires that are your 12v dc, red/orange, green, blue and maybe a white. You need to hook red/orange, green to the other. Your blue is a ground/relay for your original switch that can be joined with your negative. Still clarifying the rest.
