Hello and welcome to our presentation  today we’re going to talk tankless  before me here you see a couple of  tankless units we have laid out these  are both staged up ready for inspection  and pre plumbing first thing you want to  do when you receive your unit is you  want to open it up check-in it out make  sure it’s in good shape make there’s no  problems with it and make sure you have  somewhat of an understanding of it also  you want to make sure you get all the  all of the paperwork and gather all the  accessories that might be located in  that box with the appliance the next  thing you’ll want to do is inside you  should find.

What they call a template  the template is a representation of the  unit itself and it helps you to hang the  unit on the wall and gives you basically  a template that you would mount up onto  the wall and plumb it all up once you  determine your location of where the  units gonna go then you can install your  backing and all the supports that you  would need to actually mount the unit  from there I’m gonna take you around the  side here we’re gonna do a little pre  plumbing okay  let’s do a little pre plumbing so the  first thing you’re gonna do is remove  your desk caps that were on your unit  protecting it from any bad things that  might get in there that’s most units  come with those already on it next thing.

You’re gonna do is you’re going to do  what we call a little bit of thread  sealant or teflon tape I kind of like a  combination myself of a little thread  sealant called teflon paste combined  with a little teflon tape on top so  important you don’t get anything inside  the pipes you want to make sure you keep  it outside the pipes on the male threads  and you apply a little bit of thread  sealant pretty much all the way around  it  same thing on the other side so you’re  doing your hot and your cold and you’re  gonna go ahead and do the same thing you  get another connection here for your  gash gonna do the same thing on that and  again making sure you don’t get anything  inside the inlet of the pipe and if you  do keep a rag handy you can always just  wipe it away and keep it cleaned.

Because  again you just don’t want anything in  the pipe there’s lots of little valves  in there and intricate flow things that  that you don’t want to have any  impurities or anything getting caught in  there it’ll create your problems down  the road  now you go to your teflon tape teflon  tape bending on the thickness of it and  you’re on the width of it will depend on  the rounds but basically you start it on  hand  bring it around gently four or five  rounds is generally good again it  depends on the thickness of it and how  well it goes on for the most part you  start it that sealant helps to lock it  down a little bit hold it in place and  then again keeping this on the outside  the threads not letting it get inside  the threads you don’t want any little  pieces of tape or little chunks of  teflon paste or pipe dope or whatever  you have to be using getting caught in  your unit whether it be the water inlet  or the gas Inlet  okay from.

Here you’re ready for hardware  now you’ll take your hot water valve  you’re gonna pull this out of the box  the handles gonna be a little tight so  you’re gonna thread a nipple into it I’m  going in nice and hand tight grab the  handle itself work that handle back and  forth just a quarter turn is all it  needs to go and that way you’re  exercising it loosening it up okay now  you take that valve gently thread it  directly on to your hot water outlet of  your tankless unit and again you can  throw edit the majority of the way by  hand you don’t even need to put a wrench  on it until the end so you can leave  that last turn now you want to take your  backup branch and protect the outlet of  that tankless water heater so you don’t  put any undue stress on that take your  other wrench and bring this around.

One  last turn and you can feel it it’s  getting nice and snug which is exactly  what you want now I’m gonna leave this  one just a little bit shy of the other  one depending on what my positioning is  gonna be just to make it easier for me  now I’m gonna take my cold valve I’m  gonna do the same thing with that I need  to wind my nipple in and I need to  loosen up this ball so you just work  that handle back and forth loosening it  up making sure everything’s working and  doing what it’s supposed to do  now gently thread that one then again  for the most part you can thread almost  the entire way by hand without even  putting a wrench on it once it starts  getting pretty tight that’s when you  want to deal with it as far as putting a  wrench on it not wiping yourself out if  it’s hurting your hand.

It’s getting  pretty tight now we’re gonna go ahead  slip our wrench up on the backside but  because we’re reduced on room on this  backside I’m gonna go ahead and show you  a little trick here where you want to  prevent  this outlet on the valve from rounding  or overlain so you’re going to thread a  nipple into it to protect it and then  you can use your wrench on the backside  here and push this down position  continue your positioning of the cold  water valve now we’re gonna take it yes  pass that inlet for the gas so there’s  no conflict there and as you can see  we’re a little further than we are on  this valve which is okay he’s not a  problem now you’ll take your up other  fitting here for your gas and we’re  gonna thread that on little adjustment  and again good and snug doesn’t have to  be super tight you don’t want to break  wrench trying to tighten the thing up  let’s get it tight as you can see you  don’t see a lot of strain on me now.

I’m  at that point that I’m as far as I want  to go that it feels like I’m getting a  little resistance so now I’m gonna put a  little backup you switch out here I’m  gonna use my channel locks and I’m just  gonna back this connection up so I don’t  strain it or stress it and give it that  last little turn just to make sure it’s  tight okay now from that you want to  take a look at it and see if your how  your alignment is on your valves you’d  like to have these parallel so I’m gonna  go ahead and make a little adjustment  here just to get these valves in a  little cleaner position about right  there I’m leave it there for now that  looks pretty good good clearance good  access to the handles a little bit out  of whack I can go a little further if I  like right there  and that looks clean enough now from  there you would depending on what you’re  roughing is you need to run a nipple  extending out of each valve and that’s  going to make your final connection so  with that I’m gonna take a little bit of  teflon paste I’ve already pre plumbed  mice rough-in.

So I know where I want to  be with it and I know that this nipple  here is going to be absolutely perfect  for what I’m trying to do you can take  your teflon tape so a really easy way to  do this take one finger place it up here  take your other finger place it down  tuck it into your paste now you see the  paste kind of holds it and now you start  your line on it locking it down pulling  and stretching then you can try to stay  out of the inside of the peple right on  the exterior of it like so and again a  little bit of paste not a whole lot just  a thin layer just enough to hold your  tape in place and I kind of like to  reverse it as opposed to forward forward  would be the other direction coming this  way it just seems to make it a little  easier to keep that tension on it give  you a nice tight wrap  roll those in always keep your rag handy  you always want to wipe your hands down  or you end up getting teflon paste and  whatever do you’ve gotten on your hands  over everything which is never good okay  now we need to tighten up this nipple so  on that again we don’t want we’ve got  our valves off position where we want  them so we might make sure they don’t  move.
