 All right, so we've got another boiler here It's another well in the plane high efficiency. I shouldn't say another the other one was a monk skin Basically the complaint was the office area was the only one it was getting too hot This is a primary secondary loop. So same thing goes up to the header comes right back down You got one circulator there. You got your main circulator for the whole loop of the building. This is a commercial building We've got a zone valve for the offices right here and so basically I had the Guy to show me around so I went ahead and looked at some of these things But I got to do them yet to make the repairs the zone valve here you can see that the Gearing in it springs and stuff. It's not working right. It's stuck so what I did is I got up there on the ladder and I was able to Rotate the little valve back and forth and you can hear the water go through quickly and stop when I turn it the other direction It's very easy to turn so I'm not worried about it being gummed up But that right there is our initial problem But he also has other issues He's got a pressure gas pressure safety here That is on the incoming side of the gas line basically that control there triggers if the incoming gas pressure gets too high These boilers are negative pressure gas valves Meaning that all that valve does is open up then the draft motor is responsible for pouring the gas into the boiler So if that draft motor stops, it doesn't pull no gas in that Alleviates happen to have a pressure switch that goes bad. Got our ignition system here that will go ahead and clean It's got a condensate trap here, which is nothing more than a hose. We're going to go ahead and take that out and clean it up Technically these boiler plates should be cleaned out once a year if it's like their smaller versions I need to double check on that but it's got sensors on the supply and return that are monitored over here and There so it maintains Making sure that the temperature coming in and going out is correct And this is also has a reset which is there's an outdoor sensor outside So when it's mild temperatures this boiler will not go to full fire It'll modulate higher and higher as it gets colder and colder. That way you're not wasting a lot of extra gas the pop-off here is leaking so I'm gonna have to go ahead and get that replaced It so I got the numbers on that so we just got to get that replaced yet And then when they replaced the boiler, they just kept the old expansion tanks, which we're bleeding those out now I only got water coming out of the smallest one the bigger one I took the valve completely out when we're running a rod up in there That was a another concern of mine just in case maybe that's why the pop-off is tripping Even though the pressure didn't look like it was all that high Exhaust stacks look like they were ran correct. They look all right. They look like they're six inch PVC pipes Is what we got going on there? terminate out here So another issue like I said that we're having with that gas pressure Triggering there. I gotta find out what my maximum incoming is make sure those are set right We follow the gas line outside. I do have a regulator out here So we're gonna double check see if that can maybe be adjusted possibly it's on the other side of the gas meter and when you come out and around to over here you can see that the Gas meter coming in it's medium pressure at least Could be possibly high, but I don't think we have high out here. It's hard to say. I think it's medium pressure So basically it comes in and loops back over there Basically, he said that everything works fine when it gets colder, which means there's more load on the gas system and When the all the people's furnaces come on pressure drops and it falls probably within limits So I don't know if there's gonna be a whole lot we can do with it. So That's that's what we got going on Yeah, it's still draining Let's see if we can fit this Rod up there and get that cleaned out a little bit or I Don't think so See if this one here. Well Something seems to kind of odd that that's not got any anything at all draining out of it Let me go ahead and just open it in in there. See if that makes a difference. I just had this funny feeling that This one's got all the water, but the other one doesn't I figured this probably wasn't draining. I mean granted they have a little Tube in there it goes so far up these were Popular before my time But basically it's usually goes somewhere in there and usually drain it down to that but since there's nothing coming out I have no way of knowing this site last here Looks like there's water all up in there. It's just really hard to tell Without taking apart and cleaning if I go to clean it chances are it's probably gonna break Luckily they put a bulb out there to shut it down Which made it easy to isolate it now when I did this off I had to turn the boiler off because if I valve this off, there should be no room for expansion And then you're gonna be blowing your pop off no matter what so you definitely don't want to do this with the boiler running Rod and tell I don't know if these are still available or not There's a little needle valve that goes in if it usually you open it up All right, so we've got the spout ball you can see when we open it up But the water is coming up Even after all this draining So this tank was completely waterlogged, which it's a good size This other one's not too small, but it's not even half the size So this one was probably the only one working whether or not that was enough I don't know where I get this plastic place that broke up in the corner the small one There's six and a half inches Pretty much made a fairly smooth break got a little bit of a chip there That's gonna be down below the rubber. We've got some Glass repair kit here I like that these do not have to be super tight tip side up to the top Just in case There we go Crack out a bottom All right, so we got that pipe doped with some gray stuff got our side glasses back in Go ahead and open that up The fill valve is right down there And it's filling We'll see what kind of water levels we get You know, this should never have water in it But why in the hell did they tighten it this tight? This is stupid stuff people do It's copper and brass. It did not freakin seize up Okay, it's 550,000 BTU boiler I got a control here that's capable of doing 790,000 We got our three-quarter inch there. You got to make sure these are sized properly The pressure is correct and the BTU capacity my personal preference is to do a double Try this pro dope out I've never had a leak on one that you double up Now that pop-off relief now the tube for the pop-off that was a little bit bigger than the incoming So we're gonna have to size it to the valve here This is supposed to be able to leave three inches off the floor. Maybe it's two. You got to check your local rules so Go right there should Should clear us Here's something that never happens Valve must be tested periodically by a tripping safety lever to ensure it's functioning properly Most of the time if it hasn't been done on a regular basis and never wants to reset and then you come along and do it And then you wish you wouldn't because then you're gonna have to go track down a valve Take this excess off There you go All about trying to make it look good. So we've got our pop-off on there comes down to the floor Reason for that so you don't scald somebody Task Force wrenches. I've had these things since I started. I don't do crap loads But here's a no-namer ridges nice, but it's nearly four times the cost and it's you know I haven't found it to be worth it for me. I'm not a full-time plumber though So it's not a big deal place your tools by the door. So when you leave, you know, you're gonna pass over them Just like my little light up there end up forgetting that We got that done Now we can open this valve back up This one actually has a spiral vent. So it should catch any air Now they have a power-stealing thermostat. They put on there. It's one of those Old looks like a T87, but it's not You're gonna have to put a bleed resistor across here There's what that other valve should have done. It should have retracted on its own It's got a spring there And that spring pulls it back You can lock it into place And actually hold it there and then once it powers again It'll suck over a little bit further and a release and come back to the auto position So you can do that or say it's not working right you can lock it in that position Kind of in switch on it to prove that it's open before it lets it go to the next stage But th and tr basically is our wires there and that's going to power it open. It's just a 24 volt. Oh My goodness Made in the USA That's crazy that little valve Just turns out Right there. That's all it does. So there we go So basically I've locked it in to the stem then rotated it now Oh, yeah, that's real impressive. All right, not not real impressed So it just kicked on Getting ready to modulate That's a good thing. I got a clean-ass sensor yet and clean that trap out What's interesting is they actually have a thermostat in here that just is for the boiler So as long as this thing's not at temperature the boiler won't run So it's kind of like a master stat just to keep the boiler hot then These thermostats over here, which are a little old This one controls the ceiling heat Which is coil here Coil there coil over there And another coil up there. So she's cranking out on my valve That's always a good thing Leaking down there Still gonna check out that gas. That's a little out of whack But it sounds like it's not something it just started It's been doing it for a long time. Okay, if you look at the water level That one there is just about a quarter of the way And stop with three the other one Really hasn't done much it probably if you line them up is probably at the very bottom Actually, I see water It's a little bit of a leaky jerk. I've taken that up All right, you see a little bit of bubbles around that bottom packing that So we got that how we need to open that up. Oh, there we go There's the water won't help that's leaking like that because that'll just bleed on my airway that we're using that as a buffer We'll make sure these are open But she does so we're quarter of the way here Quarter of the way there That gives you a buffer here for your expansion of the water when it gets hot In reality since they got a valve here, which I normally would take that valve off I would never leave that on there because if somebody comes in there would shut that They could cause it to blow the water all over the floor And that could cause a lot of property damage to put it on the type of building and stuff like that a Lot of times what I'll do is I'll take the handle off and wire tie it to the valve That way somebody has to deliberately come in and actually screw with it and change it But it's in reality Since I'm the last one touching it That's what I'm gonna do You know it don't matter what the other person did who installed it when it comes down to it. You're the one that's touched it last So we're gonna go ahead Move that off. She's getting hot for sure, but I got really lucky Basically, here's the one I need There's what he normally used for residential and stuff most your stuff You can see there's a little bit of a size difference there Run a five point three make it just shut off. That looks like a shut off. It's jumped up to seven Shut off here. Just make sure All right, so we got that one drained completely out in another telemarketer colony. I love it So you're gonna be absolutely Bull crap to do that control baby. I like to call it finger control though If you got finger control, you can have trigger control You can have love control you can have all kinds of control Because you're in control. So anyhow I think shut down We're gonna go ahead and power this down. We're gonna clean that sensor They tend to get all carboned. Well, they get corroded Best way to say it. You can see that they never taken that apart and clean it anytime lately There we go. Don't look too bad We'll go ahead and clean it off Like I said a million times my favorite is stainless steel brush If I can do that to my skin, I'm not leaving grooves in my metal. So that's why I like to Use the stainless steel brush You can use a brass one too. I suspect but Stainless steel comes in handy if you need to clean up the aluminum for solder jog or something like that That way you got one brush for everything They're doing the spark and the flame sense off the same rod, which I've never been a real big fan of That there's just as important at your ground reference. So Make sure you clean that up, too And you know, like I've said a million times guys, this is more for my young guys my new guys Stuff like that. I'm just repeating things that most of you guys that have been in the field forever No, so it's not like I'm showboating or anything like that It's just putting it out there for the ones that don't get to see it. Don't have any mentors don't have anybody out there to Not saying I'm something great here At least I'm doing it. It's got a teardrop see the teardrop. We can also take a look inside there It's pretty clean the if it's the same maintenance maintenance Recommendation that the ultra 155 has then it will be Should be cleaned once a year every two years and you got our gaskets which looks like they've used red silicone on this one now for putting it back in Because we are dealing with the aluminum And I don't want to break it and then not have one and leave them without heat because that's one of the things You always got to watch out for You don't want to come in for something that you know, they at least had heat And then you leave them with no heat because that can happen that kind of it's not good Keep hearing water, but I'm thinking it's the drain. Okay, so we're getting snug there It's got a flame sensor readout on this. I'll tell you exactly how strong the sensor signal is so Which is pretty Pretty cool Yeah, it's up right at 14 pound or 14 inches So I don't know why that would be triggered. That's a little odd. I Wonder if it's triggered on a low end Because it has low in here too So these are set correctly. I can't change them. So we're gonna leave those alone 14 is what it says on the outside of the boiler That's its maximum pressure It has a minimum Yeah Doesn't have a minimum listed a minimum. That's kind of like a cinnamon And then they're not yeah, I'm not sure why that's tripping. I mean we are technically in a safe spot, so I Thought of them maybe that the gauge Might be inaccurate. That's about it. It's about the only it could be unless it's actually peaking what you need to have somebody here with a meter that can Monitor it that way What she always do before you leave Cyclo from the thermostat That right there is probably one of the most important lessons you'll ever learn About the time you leave a disconnect off on the roof And you got to go back an hour to get back to where you were at you won't do it again more than two or three times supply sensor attached return sensor attached outdoor sensor attached and Basically what this does is they have a reset point as they call it so when it gets down to zero out Which you can adjust that it will literally go up to maximum capacity based off of What the outdoor temperature is we got our clock set that way we know what our date and our clock and time is says target 140 right at 140 supply 131 125 for return so I'm sure it's got a variance in between there so much this thing should be good to go mandatory water treatment must include the Sentinel X 100 inhibitor to the system of damage at the boiler heat exchanger So yeah, they have a test kit and stuff definitely on aluminum heat exchangers. You're supposed to have some sort of Inhibitor in there to try to keep them from corroded and stuff like that So make sure you follow in the manufacturers Recommendations on that well guys Hopefully you enjoyed the video if you did please give it thumbs up And if you want to see more make sure you subscribe and click that notification bell till next time guys We'll catch you on the next one
