Okay hi my name is Dave and this is my first video ever being posted to so bear with me if I stumble on words st. I’m a lot but this is my video on how to replace my six gallon propane / electric hot water heater with a new tankless hot water heater and when I was doing searches and YouTube trying to find a video that really gave me the detail that I wanted I didn’t find much I did find a couple I did probably one specifically with this unit but he was installing into wall infrastructure so didn’t have any finish in there so he could wire directly to it he didn’t have to try to wiring to his existing switch on the control panel.
He could wire his propane those type of things and I was looking for one that was in a newer you know finished model that we could place out so real quick this is a this is a precision temp Rd 550 I mean since 55,000 BTUs gives you up to 88 degree temperature rise so you know when I started looking at this we’re a family of four look we like to take showers and we want to take hot showers like you do at home let’s face it six hours of water just isn’t enough you know.
You’re on off of the water and then it’s colder you’re camping in colder weather look the bathroom the bathroom is not as warm as it could be so when you turn it off you’re kind of cold so sort of looking around you can spend whatever you want I chose to go top-of-the-line I figured if I’m going to spend X time I will plan to spend a few bucks more and just get the get the one with the most the most power for now so with that the first thing I did is we have to be safe of course you want to make sure that your propane is shut off I shut my protein off all the way in front of the stores you might have a on and off valve somewhere below the hot water heater or maybe somewhere inside.
But I chose a dish of hot water off at the fun electric you know all we really need for the new installation is our 12 volt DC that’s our 12 volt direct current coming from our battery this this model also has a 110 120 connection for the electric component so that when you’re when you’re plugged in at a campground or wherever you can run combination gas electric give you a higher recovery rate we won’t need that log 10 connection with this model because this only needs the 12 the 12 volt DC draw to to ignite and then the propane as long as you have an endless supply of or an endless supply of water and then a supply of propane you can take endless hot you know an endless hot water shower until you run out of one or the other or both so with that all Santa shut that off I’ll open this up and I’ve done some.
I’ve done some pre-work before you know starting this video I prepped some done some things ahead of time so I didn’t have to do it in the video wait for those things to occur so I’ll try to go through those things let me move the camera up here a little bit and then show the hot water heater what we’re going to do here so this is our existing unit and so obviously one of the things you want to do is um you want to drain it make sure you drain your hot water of course water wasn’t hot but there’s a plug here that I removed take your pressure relief valve put it in the middle position that’ll leave it open and allow allow for air to come through a lot for this dream work quickly.
I also I also again my propane shutoff I also unthreaded my propane source and pulled the propane hose you know with the fitting back on the inside so from that same point on the outside here I’m prepped I’m ready to go my next my next thing will be to undo all the fasteners remove all the fasteners and you know using a putty knife I’m going to try a plastic one first because you know I don’t want to you know damage or Knick the outside of my trailer if I can help it I do have a metal putty knife in case that doesn’t work let me show some of the pieces that since we’re on the outside here make sure some of the pieces that were going to need I tried to again I tried to prep everything ahead of time you know the last thing you which II hate always going through is running around the Home Depot when you’re in the middle of a project so you want to UM.
I wanted to try to to prep so inside your trailer you have you probably have it’s a newer trail you probably have PEX tubing very flexible and very easy to use and work with and then then they make these really sweet slick sharkbite fittings that just compress on to the end and you’re good so I’ve bought some extra this case I need to make a mod once I get the the the new heater in I cause of course you always need that you know putty knives instead you need your major drill for the move and the fasteners the hot water heater.
Itself they give you two sharkbite fittings for the back of the for the hot water out and the cold water in so these are half-inch – I don’t know if that’s 3/8 or what that fitting is but they give you those and then iid shark boat I bought are just in case because I’m not sure I’m going to need a couple a couple pieces of pecs together to make the make the lines that I need or I bought some extra nineties 1/2 1/2 inch knife to go real important leak detector you know once you make your propane connection last thing you want is your propane leaking inside your trailer so about some of that look at that some some number one it’s first if you noticed my trailer is gray and black and this is white so I bought some black spray-paint this this door easily comes off the only thing I’ll have to tape up is this precision temp emblem I’ll take this off cut that out make that all nice.
I’ll probably cover this and then unlike scuffs and it just a little bit to help the spray paint adhere but I think on the back on the back side we’re going to do first is kind of just test it spray painted spray paint the backside a little bit see if it here is good see if it sticks and if it cures and dries well then I’ll just spray paint the rest and make it match um don’t have the butyl tape out here but I do have rolled butyl tape we’re going to put butyl tape behind the flanges when we when we put this back on and of course some good old silicone waterproof caulk to caulk the outside once we’re done okay so this is the this is the inside of remove the panel and I have mmm prepped like I said I wanted to be you know as far ahead of the game as.
I could and I had some just you know concerns I’m not I’m not an expert at this and I don’t do this all the time I just wanted to look at things be sure I was playing doubt so you can see I’ve removed the the hot water out and I’ve cut off the end cuz the end we won’t we didn’t need we won’t need and I have there’s my propane supply that I have just resting there my cold water is again the ends are cut off now at the 110 the 110 supply is right there okay um now what I did for that is again you want to be safe so I have this I have this voltage detector that I picked up at Home Depot some time ago.
I wanted to make sure this one 10 wire is is safe so with the voltage meter on if I place this against the wall ten wire you see that it’s a it’s not it’s not doing anything it’s there’s no there’s no car and that’s because over here my my electric box my circuit panel I have the water heater in the off position so just to show you I will turn it back on and when I put the voltage detector up there you can see it lights up red it’s blinking and it makes a sound but you know there’s there’s the voltage there so we’re going to turn that back off and go back over here and we are we should be safe there should be no voltage coming through anywhere there now what I’m going to do there is I’m just going to come back a little bit and I’m just going to simply cut that cut that wire right now to remove that now that’s the 110-120 wiring that.
I said we’re not going to need anymore so once I cut that I’m going to tape that off I’m going to keep this circuit breaker off I might I might talk to some friends and see what else I should do that maybe I should remove the the circuit breaker I don’t know but we won’t need that and that’ll be that’ll remain in the off position nobody really touches the control the circuit box except me so we shouldn’t have any any issues there now though our concern is we need the we need 12 volt the what 12 volt 110 and probably can’t see it too well in there but you see the wiring come from the front of the hot water heater and that’s where our 12 volt connection and switches 12 volt from our switches on the control panel were connected and that’s.
