Now millivolts is of course not a lot of power no right but it is enough to run the valve and that gets distributed from the thermocouple into the valve on this tip right here okay now as we stated the electronic valve is going to need a lot more power these will predict traditionally produce anywhere from about 10 to 30 millivolts 30 is about the maximum pretty much going to see out of one of these but 10 is what you’re looking for now that is not enough to run an electronic right now you’re going to have to have a little bit more power and what we’re going to use is this right here this is what is called a thermal eyal this opened up.
Where you can get a good look at it here the thing is is they work identical there’s nothing magical about it right this area here sits inside the pilot that starts to heat up and produce our power that gets transmitted through the gas valve through this wiring connector right here that plugs into the front of the electronic control okay again it works identical to the older thermocouple right we call it a thermal pile and if you think about that name it’s actually a pile of thermocouples if I can get a little bit of power right out of one thermal couple that I can get more power out of a bundle normal couples and that’s basically what this is is a bundle of thermocouples in one housing we heat up this tip we can produce a whole lot more power most of the time you’re going to see anywhere between 350 up to maybe 900 millivolt right about standard humble pie.
That’s going to drop a little bit as you point out as age as it goes on but 350 is what we need to run the valve but it will run anywhere from 350 upwards yeah so 350 is a number that you want to remember whenever you’re doing any kind of troubleshooting we’re going to get to that when we get to doing trouble when we touch on troubleshooting we’re going to talk about those numbers and again as we pointed out earlier you have that PDF there all these years are going to be on that PDF we encourage you to print that out keep that it’s a great resource yeah and I mean this is this is we were just going to talk a little bit about you know the difference is this is what we’re really going to get into now we’re going to talk about the troubleshooting and really again you can follow along using these PDFs which is on right below the screen or the window in the and on the website just right below that there’s two links that you can get to PDF there.
We go right there there they are right there you can go ahead and download those PDFs I can go ahead and press one show you what it looks like yeah that’s what you’ll get if you press on that length and that’s what we’re at right now we’re going to talk about the mechanical style troubleshooting and specifically really when you you look at we’ve got a lot of we got a call center here so we know what’s going on in the field and the number one call really is is no hot water is what you usually get and it happens on install and it can happen over time but it’s it’s no hot water that means that they have no hot water come from the water heater so the first thing they’re going to want to do is to make sure that it is the water heater so they’re going to want to have to go to you know all the faucets make sure that
It is coming from the water heater but once we do that you know let’s let’s talk about troubleshooting we’re going to use a base actually we’ve got a couple of bases here first thing we’re going to look at is the mechanical style and all this is is this is just the bottom of a standard water heater this lets us open this thing up so you guys can get a get a look at what’s going on on the inside out as we perform these tests and those type of things just gives you a little bit better view and as you pointed out that traditionally the number one call you’re going to get to no hot water right now there could be a lot of reasons as to why they have no hot water but typically all the the ins user is going to say is hey I don’t have any out walk so when we go out there what do we do yeah no hot water call what do I do when I first show up on the job and that’s what that’s what we’re going to cover today the steps you need to look at when when you’re faced with a no hot water call.
I mean it’s gonna we’re really going to just kind of break it down into two different roads that they can take so let’s go ahead and say we’re coming out to a house we verified that we have no hot water and it’s it’s the water heater so what’s the first thing we’re going to do when we come to the house okay the first thing you want to do is verify whether or not the pilot is lit or gumming we know it’s a no hot water call right so we assume that the water heater itself is not producing any hot water and as Jerry point out we’re going to have them make sure that that’s all over okay it’s not just one specific location but if there’s no hot water in the entire home or apartment or whatever it isn’t you’re looking at then we know we have an issue the first thing you want to do is make sure that you have a pilot lid you’re going to have to look inside this little small inspection window and look and see.
If that pilot is present now sometimes this can be difficult you guys know how it is you get out to an apartment complex you go inside the unit you open up the closet door there’s the water heater but what else is there yeah everything else and their coats and Christmas trees and you know it’s really pack everything yeah exactly everything else is around that water heater and it’s going to be all the way down at the bottom you know sometimes sometimes it is a little bit difficult you get down on your belly a little bit and look inside this little light but what we’re looking for is just a clear blue light a lot of people think well if I’m looking for a pilot I expect to see this big large flame on the inside of the water here right ten years ago that was true but as as energy efficiency has become the norm and water heaters that pilot has been reduced over the years again that thing is burning 24 hours a day 7 days a week inside the bottom of the water heater is so smaller you can make that pilot the more energy savings you can get so all you’re going to be looking for is what looks like a clear LED light on your PDF .
There’s a picture of that so you can kind of see what you’re going to be looking for and it could be to the far left or far right and when you look inside this viewing window but there we go there’s a shot right there there’s your pilot that you’re looking for that’s that’s typically what you’re going to see and you may need it like it says in the PDF you may need to dim the room lights because it may be kind of hard to see especially if there’s a lot of light in the room it is sometimes if there’s a lot keep in mind it’s dark inside here right because this is underneath the water heater normally so if there’s a lot of light in the room this little glass has a tendency to kind of act like a mirror yes is he right so you you get in there and you got a flashlight in your mouth you’re standing on your head and you’re trying to look inside this thing and you look inside the glass and you don’t see anything but your own eyeballs right because it’s just acting in the mirror so turning those lights down in the room will let you see inside the heater a lot easier okay so once we do that we verified that the pilots out the first thing that you’re going to want to do is we’re going to try to relight the pilot.
Yes there’s no pilot that’s the first thing we want to do is go ahead and relight that pipe yes follow the lighting instructions that are on the water heater they’re going to tell you step by step how to do that that once you try to do that this is the the thing that you know you run into I’m trying to relight the pilot I can’t get the pilot to light yeah where do I go from there usually what happens what we’re going to have to do is of course we’re going to turn our gas control valve to the pilot lighting position right and we’re going to have to push down on that pilot knob right now when we push this down now we’re letting gas flow through that pilot tube out to the pilot orifice right now the next thing we’re going to have to do is click off our igniter right while we’re holding down that pilot knob we’re going to have to hit this igniter button now if you can get it close up let’s see if we get a close-up right there on the igniter and see if we can catch the spark yeah I think you can see you can see a little guess you’re either gonna light.
