Hey guys thanks for checking out the video, as I was editing it I noticed I may have misspoken on a few small things here and there so please take it easy on me. I can always cover these things on my live stream on Sunday evening at 8:30 p.m. Eastern. If you haven't subscribed already please consider doing so and smashing your thumb 👍👍
Great video... spoken like a real service tech!!! Thank you
@@harbbains66 I play one on RUclips 🙈🤣
me and my ladies, Beulah and Bertha (1925 Kewanee Portable Smokeless Firebox Boilers with 4 inch tubes thank you, very well done.. if they only had done the minimums...
Those sound like some nice ladies 😉
Good job Rick, not talking crap on you, unless you want me too.
Thanks for checking it out!
Nice troubleshooting and work Rick. I've never done a whole lot with boilers but trying to learn.
Thank you!
You have excellent video's. I fixed tons of old school HVAC epuipment but don't have much experience on the new high efficiency equipment. Thanks for the video's.
Thanks for the support🤜🤛👍👍
Great video, Something different . I watch all your videos and 94.6 % of the commercials. Thanks again
Thanks my man 👍👍 that means a lot 🤜🤛
Good info on those old expansion tanks. Thanks for the video!
Thanks 4 checking it out🤜🤛👍👍
Thank you!
You’re a true blessing and mentor anyone says different tell them to go fly a kite.
Thanks man 👍👍. I'm just trying to help people out while having a little fun, maybe I can become famous one day 🤣🤣😉
For relief valve I always use black pipe and nipple or copper pipe with copper union so in future I do not have to cut and solider it again Nice video
Good pointer👍👍. Thanks for checking it out!
I am happy that you are helping the new personal in the business !!
It's kind of fun 🤓👍👍
Very talented, thank you for these videos. Making better technicians everyday!
Thanks Hunter that's cool of you to say that!
PVC venting should be replaced.
Discoloration shows it also over heated beyond or close to its capacity and has been compromised. Great job!
I have abandoned many of those expansion tanks and installed commercial bladder type tanks. Great video
I wasn't sure what size it would take with that being 550,000 BTU plus they look like they were in good shape, they were pretty blue LOL
I have as well Lee. Those are fancy though....
as i said before, a man of many talents, thanks for the video.
Everyday I learn something new 👍👍
That zone valve I think is a Taco made in Cranston R.l. great quality products from a great manufacturer. Yes I think 6" is correct on the pop off but locals push the issue. On a saftey note did a boiler in a commercial building and got water on mech flr and maintenance guy walked in fell got hurt and the company I worked for was reliable. So I learned to use a bucket the hard way. Ass chew wasn't the best. Lolol. Usually high pressure gas is usually painted yellow and should be labeled accordingly. Great video like you said for guys that don't have a mentor to give them advise. I don't mean anything by it, just try to help and give hints of what I learned in the trade for many years. All good. Thank you for the video and experience,knowledge, and for Sunday nights of your time bud. Stay safe, be the best you can be and please help save a dying trade of great guys in it. Peace.
I believe your correct on the 6" off the ground. I don't have all the rules memorized. I was more or less going off of what I thought it was but said to double check the local code to cover there butt. Thanks for the information on the high pressure color. I believe we only have low and med. pressure in town. I do so many different things in the field I can't ever be a expert at all of it, there's just to much to remember.
Very true no one can remember every little thing in the trade. You are very welcome. Have a good week and please be safe.
As a first time viewer of your channel I noticed you mention repeating some things a lot. Please keep doing this! Not everyone watching your videos will be a long time viewer, and it shows your new viewers what they can learn from you. Not only that, but if you have people working for you, it helps them learn.
Another channel that does this is HVACR videos, and he does a great job conveying tips, tricks, and things to keep in mind that newer techs wouldn’t know to look for or do.
I’m not in the HVAC industry, but work creating equipment, processes, and training material for use in our factory. One of the things the training material for us trainers discusses is frequently repeating instructions to our trainees.
For example when introducing them to a new process, you guide them through the whole thing verbally once with your written work instructions. You then go step by step and actually perform the process: before you follow an instruction you tell them what you’re about to do, then you actually do the step while again repeating what you’re doing. It sounds stupid and repetitive. It is repetitive, but not stupid! By the time you finish with the trainee they are able to do the entire process without having to look at the work instructions for each step.
There’s a reason why athletes, musicians, etc. practice. It’s because repetition works!
I really appreciate your perspective and I will try to start implementing that into the videos 👍. Sometimes when I'm making these I feel like either I'm talking over or under people's head and because it's such a wide range of experience levels it's hard to balance that. Thanks again 👍👍
Did a water heater pressure/ relief change where the pressure/ temp relief pipe had been tightened so tight i had to use 2 24 inch pipe wrenches to get them separated. Way to tight. And it was black pipe so I went to copper and got rid of the black pipe.
I hate dumb people 😡. Nothing surprises me anymore, it just makes me say why? 😲
Another good video! Amazing to see that installers everywhere cannot read installation instructions or textbooks. System loop pump, boiler, air eliminator and expansion tanks all in the wrong location to help get the air. Pump away!
There's a lot of issues similar to that around here. It's been my experience that a lot of companies don't put a lot of time into training and a lot of employees don't care enough to learn unfortunately. I appreciate the feedback and thank you for watching 👍👍
I got a ultra 155 series 2 that has been great for the past 15 years. Only the fan had to be replaced at age 14. Regular maintenance is the key.
Yep, gotta flush that heat exchanger preferably every year. Thanks for the feedback 👍👍
Thanks for sharing. I did take a boiler class a long time ago but never had any exposure to them and this is interesting to see. All I can remember is the safeties were double redundancy. I would have to learn the piping portion again.
No problems Brad! Thanks for checking it out and leaving a comment!
Damn good job. I'm gonna have to keep watching. Between you and hackfree, I think I might get a leg up. Keeper up man. You're awesome!
Thanks for the kind words Bill, you rock!
Awesome video, especially around 19:05. Thank you sir
Thanks Chris! Your welcome!!
That's the first rule I tell someone that I'm training to do maintenance or anything you don't leave the job until you see the unit running that way there is no way for you to leave the disconnect off and then someone has to drive all the way there just for that
That's the golden rule, cycle it from the thermostat before leaving
Excellent video!
Thank you, are you a new viewer? I haven't seen you before. I appreciate the feedback 👍👍
Good vid Rick ... Your a good tutor ... Enjoyed what I watched of the live stream ... You and the Missus do a good job ...
Thanks E-Dawg 👍👍. I enjoy hearing the feedback.
Rick you don't have soft hands. Passed the test.
It makes them grip better 😲🤣🤣
I was told by people who work at a gas company that in the mornings when business start up that they have to keep ahead because the main lines gas pressure will drop which you might have seen. If it is too much they add propane which help to increase the gas pressures up.
That's interesting, thanks for the info.
This is true. The add a mixture of propane & air to keep a btu rating similar to Natural gas. Generally done at times of high demand.
Good job. There was a lot to do on that PM well I guess service call but likely due to no PM’s.
That's first time I've been there, we didn't install it so I'm not sure how often it's been serviced.
Another informative video
Thanks Rick
Thanks Tony I appreciate that. I may have made a few misspoken words here and there but there was a lot of things to be said and I don't always have them all memorized.👍👍
Your videos are very helpful Rick, keep them coming man!
Thanks for saying that Zander!👍👍
Very interesting. I don't see many boiler videos.
I don't post a lot of them because they don't seem to get the views. Boilers always seems to be the same issues that you seen here. Bad water fill valves, P/T valves, expansion tanks and air removal systems going bad. Thanks for the feedback and for watching 👍👍
Great video! Keep it up!
Thank you Everything!
Awesome content.
Thanks for the feedback!
Have had interment gas pressure issues tripping high pressure saftey. Vent on regulator being plugged was issue.
If I go back I'll need to look for that 👍👍
Great video Rick! I enjoyed it!
Thanks Ryan 🤜🤛👍👍
The gas line pressure drop of 1.7" is pretty high (7" off minus 5.3" running). Either piping is too small, regulator is too small, or regulator isn't working right. Some codes spec 0.5" drop max, I look for problems when it goes below 6". Couldn't tell in the video but gas pipe needs to be 1-1/4" or larger for 550k. Regulators require periodic replacement just like boiler feed regulators because the rubber diaphragms inside get hard, and the springs get weak, valve sticks, vents get blocked, etc. especially being outside. I'd put the boiler in manual low fire and set the regulator to have at least 7" at the boiler (some gas has to be flowing to set a regulator correctly, a lot of techs miss this). Might need to turn up the regulator a bit to keep 7-8" on low fire. When the boiler shuts off the pressure should rise a little bit due to regulator lockup, if it goes up more than 1" or so, the regulator might be bad or you have a restriction. If code allows, I'd move the regulator inside right next to the boiler for the most consistent input pressure, otherwise you might need to upgrade the piping and/or replace the regulator. If you still have pressure problems you should call the gas company to check their regulator and gas pressure on the meter, they can go bad too.
I've noticed the pressure tends to swing a lot more than it should. The customer said they replaced the regulator, I think twice and had the gas company out. This is real close to a oil refinery, I can't help but wonder if they are causing major draws on the system line causing spikes. I believe it was the high pressure switch that was tripping and not the low but because the person I spoke with said it's been happening since the install years ago and after several checks from the gas company and the original installer contractor figured it was a losing battle.
Thank you for all the good information 👍👍
@@HVACRSurvival No way it should trip high pressure if the regulators are working right, they should close it off before it gets to 14".
@@TechnicalLee true, maybe it was the low pressure, he was a delivery guy I spoke with then he left after showing me everything so I didn't get a chance to get more information from him.
Good one Rick 👍
Thanks Greg 🇺🇸🇺🇸🤜🤛👍👍
I can hardly imagine that the few threaded rods should carry 2 containers that big if they are also full. Would be too risky for me personally to build something like that. But apart from that, don't you risk destroying the new valve when soldering on the pressure relief valve? Although, viewed from below, they're not as big as I thought. Looked like easily 200L per container
Everything is still working good 👍👍
It terrified me the way you attacked that sensing probe with the wire brush. I wouldn't dream of doing that unless I had a spare replacement handy, once the metal rod breaks free of the ceramic then that's it, scrapped.
I look like I was roughing it up pretty good but I haven't broke any yet like that. Unfortunately I cleaned a million of these sensors.
If that pressure relief was blowing, there is probably little inhibitor left in the system. With that system out of the way it could have been using 100s os gallons of water and just draining right at the floor drain with no one to notice.
Good point👍👍. They didn't call me because of the pop-off valve they called me just because the office was too hot. I found all these other things by doing a investigative diagnostic.
lol, if there was ever inhibitor to start with! ( probably not)
Regulator is probably leaking by. Change it
The guy said they've changed it multiple times, this is the first time I've ever been there. The city is known for gas issues down on this part of town.
My professor wants me to describe each of the four components of a hydronic system. Im confused it has more than four components lol.
Either pick the most important ones to make the system run or ask him why he only wants four? It's kind of like an air conditioner. You got a compressor, a metering device, a condenser and a evaporator. But some ac units might have a ton of other controls.
How long have you worked on commercial boilers and what training did you undergo before working on them? did you just figure most of it out on your own or is there a school for commercial boilers?
I've done HVAC since 1995. I do a little of everything as you might have noticed on my videos. Mainly you learn as you go after learning your basics in school. There tends to be a common certain number of things that tend to go wrong on boiler systems so although they might be bigger or smaller they generally have the same parts going bad. They tend to have after work classes and a day or two classes for any particular boiler you want to learn more about.
Why blurr the blue information display?
I had programed our company name into it. I was told to keep them out of the videos if I want to make these.
@@HVACRSurvival I can understand that, keep up the good work!!
@@jesseatterberry4990 thanks Jesse, I'll try 👍👍
Spiro vent will steal air that should go into ex tank
I've never heard that before. By default the expansion tank is going to have air in it because there's no place for the air to escape to as it fills with water and it's above the system. Those tanks do not have a bladder in them like a traditional smaller expansion tank.
@@HVACRSurvival I think that's the point he's trying to make. Any air in the system may otherwise flow back into the expansion tank and stop it from getting waterlogged so quick. However the tee feeding those tanks was heading out the side of the manifold rather than the top so probably wouldn't catch much air even if it were the spiro vent.
@@Thermoelectric7 this^
You can go up in BTU with the pop off? Can you go down
You can go larger but I don't know the amount over your allowed. I'm sure there is a multiplier. But I know you can't go smaller in btu.
Scrap those compression tanks. Air seperators and compression tanks are not a good date
never have i seen something like this in a video
Is that a good thing or a bad thing? What was different?
@@HVACRSurvival idk, lol

Medium pressure?
It's the pressure the gas company uses to deliver the gas. Higher the pressure the smaller the pipe they can use to deliver the same volume of gas, this is to save money on pipe.
Doesn’t it reset the boiler loop temp vs. outside air temp?
That's basically what I was saying, the boilers water temperature will not go to full maximum temp unless the outdoor temperature reaches the set point that it is set for. Basically the colder it gets outside the hotter the boiler gets, vice versa as it gets warmer the cooler the boiler gets.
Reset schedule. It saves fuel baby
That's what they say, I've never owned a boiler so I have never experienced it firsthand but the people that we have put a high efficiency boiler in for tend to say they saved money 😁👍👍
