This video was over two hours long…so to shorten it I had to cut a lot of things out. Update:👉👉 the customer decided to not fix the RTU that had a bad blower motor but did authorize me to return and install a low pressure cut out switch for the gas. I chose a adjustable switch with a manual reset. This way if the pressure switch trips they’ll lose heat and they’ll know that they’re having issues with the gas. I also recommended that they have their gas supplier inspect all the regulators, I later found out that that first regulator at the tank was not a liquid to vapor which at the time I wasn’t 100% sure because I knew that they could’ve taken it to the bottom of the tank with the tube. Either way hope you guys enjoy the video. 👉make sure to hit like if you would please.
normally ,they tie it to the flame sensor.
Great video Rick. I thought you were work on a diesel stack at the beginning of the video. The coal was rolling🤣. Luxaire is junk and on top of that they are propane. I bet you looked like a coal miner at the end of that job. Thanks again for an interesting one.
Maybe they will get wise and install a decent system and toss the mess they have now.
Your hilarious commentary 🤣
@@fshn76 my wife asked me how I got so dirty 😂🤣👍
“Blowing diesel?”:
Thinking you meant; “rolling coal!”
Great video Rick ~ Happy New Year
😂😉👍👍yep..
Try adjusting the burner for more air until the flame turns blue (adjust the position of that shroud on each of the nozzles). This should solve future soot buildup and reduce CO emissions.
Yep. When you have that much soot its a sign its burning rich.
As a former technician love your patience working on the old equipment it's a good reminder that it's not all roses out there good job love your videos
Thank you!
You're always going to have TROLLS criticism in the comments. They don't make videos detailing what they do. They're just like you and I. Do the best Job you can do while running over 20 calls a day. You can only do what you can. I liked the educational part of your videos helps me allot in the field! Thanks for sharing!
I understand, generally, I was a person giving everybody else a hard time locally. I never used to watch TH-cam for HVAC stuff until I needed to know more about Refrigeration. Generally I try to do everything above and beyond what’s required just because it’s one of the things that I’ve come to learn the most about.
@@HVACRSurvival I've learned more on TH-cam than I did in school.. Again thanks for making great HVAC/R videos! ❣️
Looks like Niagara Falls of soot. Good lord those were in horrible condition....those Sunline models are the biggest PIA to replace the HX. Great video as always Rick
Thanks Jason!
I got the same paint markers because of you and passed a bunch out to the guys and everyone loves them.
They are much ass! They do fade in sun though.
That's quite the disaster, but I understand some people are just doing the best they can with what they've got.
Man, after watching this I am even more happy I don't work on heating equipment. You are the best, keep up the great videos.
Wow, thanks!
Its an advert for heat pumps in a way
@@liam3284 hahaha you could be right
Good video Rick, your not scared of difficult jobs!
Yeah i am always amazed at what he gets into.
Above ground propane tanks that are less than half full in winter seem to cause pressure drops then soot. Those chimneys add pressure drop as well. Thanks for a good laugh as the soot cloud came flying out.
Glad to see someone thinks the same of York/Luxaire and Goodman as I do lol, Also that is vapor withdraw tank for sure, that's just the first stage regulator to go from tank pressure to 10psi, Vaporizers are either electric or gas fired and actually heat the liquid to boil it than send it down the pipe, they work very similarly to a Unitrol on a conventional water heater. They're common up here in Northern Ontario remote mines that have huge fuel consumption demands and the tank cant boil fast enough to provide enough vapor
They used the cheapest 100$ Amazon special version of a vaporizer. It shouldn’t be within 15 ft also
@@Pippy626 There is no vaporizer there, the pipe feeding the first stage reg is coming from the top of the tank, vaporizers draw from the bottom its a first stage reg and a relief valve there
@@Byron88you are correct. It’s a cheap regulator.
I later found out that it was not the vaporizer, but at the time I wasn’t sure so because I said so many things that went along with that I left it in the video. I should’ve done a title overlay, saying that it was not.
@@HVACRSurvival All good, I enjoy the content regardless, I just figured propane was uncommon there and would just throw the info out there. Happy New Year!
Always a great day when you can smell heat exchanger issues. I wish more manufacturers would make a low pressure cut out standard in LP Kits. Where do you find an after market switch like that? Never even though to look
Googled it. Ordered on supplyhouse.com
The pilot burner usually gets a little spider webs inside it. Spent many times trying to figure out why the pilot wouldn't light. Stick some wire down there with a little hook on it. Usually will get a small spider web on the end.
I myself would always say "What fresh hell do I have today?"
🤣
I feel ya
I was a charter member of an RSES chapter, CM,CMS.
Dove into pure insanity back in 1983.
Saw Maxwell's demon twice operating in my career.
Yes, it's a real thing.
One of those beloved maintenance guys here, had a few units on a building I look after doing the same thing on natural gas, replaced the heat exchangers on them, from what I was told when the building gas system was commissioned, it was never purged and cleaned of any construction dirt, a rag was even found in the gas line for a boiler.
Wow. That’s great 🤦🤫
48 years in HVAC/R.
ENJOY ALL OF IT.
You'll retire one day and miss the insanity in a year or two.
Don’t doubt it
Rick i hate working on LP furnaces especially when they are not commmission properly. Great video Rick!
Had a similar call years ago, installers forgot to remove shipping sticker from fresh air. Was 3rd company there before it caught.
You gotta love that!
Ive used a garden hose, flooded it and found a Milwaukee small version 18v blowers fits perfectly to blow tubes out of these exchangers. Very nice work though most impressive diagnostic and service skills!
Thanks for sharing! There’s no bad ideas when you’re looking for a solution for a mess like this.
@@HVACRSurvival Get a string long enough to go all the way through the exchanger. Tie a small scrap of fabric to one end and a bristle brush the size of the tube to the other. Use an m18 vac to pull the rag end through the tube and then pull brush through. After brushing out each tube then use compressed air to blow them out.
Really good video! I've worked in the HVAC world for many years on the facility maintenance side. I commend your positive attitude and willingness to keep working thru all these crazy and unending problems! Good to see a real professional do a proper job in very adverse conditions. I'm a new subscriber after seeing this interesting video. You've got a future career as a comedian with some of those responses to unexpected disasters!
lol. Thanks for subbing, it’s funny as I read my comments I got told I’m positive yet I get others say all I do is complain 😂🤟. Thanks man!🤜🤛
Love and totally understand the sarcasm. I have had disdain for many designs of equipment I have serviced. Sometimes you look at a design and think how the heck does this even function. Oh, it doesn't that's why I'm here... 🤣
I fully feel you 👍👍
Another great vid! Always look forward to watching them
Much appreciated!
😱 What a crazy amount of soot😵😵💫
That sure seems like a large propane tank for two small heaters. Are they using the propane for other purposes? Maybe overwhelming the natural vaporization of the tank? If so, may need to add a true propane fired vaporizer.
Come to find out it wasn’t a liquid to vapor regulator, and those two tanks provided several other buildings with gas. I was also informed that they had added a lot of extra heating loads, which was likely causing the regulators frost up like that. I’m returning to Install low pressure cut out switches on the Regulators
.
@@HVACRSurvival That would be the band-aid but maybe still talk to the propane company and see if the total connected load is overwhelming the tank. Of course the vaporization rate falls along with the outside air temperature when you need it the most.
As for the gas manifold port on those valves, I use a 1/8 x 2-1/2 nipple and 1/8 coupling to extend access above the pilot tube. Connect the 1/8 tubing adapter to coupling. Comes in handy elsewhere also. 1/8 Male x Female NPT valves are also useful if checking between multiple ports at the same time with a single device.
Thanks for sharing! Good idea!
Those Luxair/York/JCI units are total ass. Changing the HX is a two person job and the better part of 4 hrs to do. You have to dismantle the collector box to get to some hidden screws and then the two through the blower housing and some in the condenser section.
Edit, forgot to mention, overfired and low airflow killed the last one we changed out, belt was worn to half its original width and filters hadn't been changed in 3 years.
Your analyzer is made by Sauerman btw.
Before I would say that that’s a bad blower motor, I would want to double check that all three phase legs are connected to that motor. It is very likely that you have a bad contactor. I have about five bad contactors producing that same result for every one time I have an actual bad blower motor. When that unit fires off…..and I have to assume that they have the correct valve modification in place for use with LP gas…. I would want to monitor the manifold pressure when everything that uses LP in that building is running. I’m guessing that that’s a very long pipe run, and it’s a long pipe run with a small diameter pipe and a low feed pressure. So, that’s my tip for you after 60 years of mechanical work.
Good repair for what you’re working with.
Nice work ethics & nice job going the extra mile ... Thx
Great video as always man! Stay warm!
Thanks! You too!
Good job Rick.
You felt it that variable wind is affecting combustion …perhaps a fan on the flue to insure constant air flow …or a proper chimney
It looks like with the half ass exhaust piping coming down off the top of that roof ledge you’re saying there’s an airflow coming across down could be causing exhaust gases to be pushed back down to the fresh air intake for the combustion causing your sitting you’re correct don’t believe those are factor authorized extension tubes and they would’ve been better off just extending them out, 12” further
Nice day at the office
I've worked on tons of those York/Luxaire units and I've never seen the burner plate locating studs with nuts on them.
Wow.. what a mess. But I laugh my ass off with you blow by blow commentary LOL.
that kind of looks like a Morton building site
Nice work as always Rick. What a mess. You did the best you could.
Yes it was, surprisingly it’s still running 🤞🤫🤣
Great Video. Thank you for sharing
Amazing 👏 craftsmanship 🫡 great job on going the distance 👏 👍
Thanks man!
I just changed 2 of those york style heat exchangers on Thursday it was a pain in the but lol the location of the screws by the blower i just had to cut them off lol 😂
Oh man! Rick, you have the patience of a patron saint!
I work on the York POS's on the daily, but i'd have run from those two, lol. You're a better man than I lol. P.S. you'll never be able to fully clean those carry-over tubes for the pilot. Just replace them! Cheers!
Thanks man!
Some say you can’t smell CO, but you can feel it burn when you breathe it in (or behind a shmuck that gutted their converters for the extra 2hp)
Man....what a hunk of junk. Excellent patience good sir.
That add on vent is changing the mixture,it should be ok ,with out it.most of the soot is at the end,but you cant brush it,unless you put a brush at the end of a fish tape.thanks for sharing.
Thanks for the info! 👍👍
Sauermann is the one I use. I’ve used others. The Sauermann has been a good one.
if the burners have adjustable air bands, they likely need adjusted for the propane conversion, while that's sure not helping. looks like you found the main issue, those goofy stacks and running out of propane or other propane piping issue. it for sure needs low pressure switches added.
That was hilarious, I didn't think you could get an RTU to roll coal!
Great video… anything can be fixed with enough time and money 👍🏻
Absolutely.
Rollin’ coal! Someone did the emissions delete!
😂😂😂
With your experience and knowledge , how many hours to complete this job?
Most of the day. A lot of it was making phone calls and verifying with people if they wanted me to proceed.
Great vid! They also make the Klein flip sockets in metric but they 3 times the standard ones price!
I’m with ya on blowing furnaces out. I still to this day prefer using air over vacuuming if conditions permit! lol.
I have tried using a garden hose on heat exchanger before in the past that was kind of a disaster and itself. Customer said they’re willing to replacing the unit so if this doesn’t work, then we’re going to sell them a new one.
Were the manifold orfices changed when the conversion kits installed?
From what I was told he did the full conversion. There was no stickers to tell me what the orifice size are manifold pressure should be.
He told me it was supposed to be 9 1/2 inches water column so that’s what I said that.
When u said Diesel exhaust I just died of laughter
"This piece of fine machinery" - lol
Good Job..
Holy soot bags santa!😂
Bud, I have been in the commercial industry for around 20 years and never ran into that.
Good find that was pretty impressive. What part of the us are you working in?
You are a really good tech many guys would have never took the time to do this correctly.
North west ohio. Thanks for the compliment🙏
Luxaire...the goodman of commercial equipment....best quote ever....i worked for a company that decided to sell goodman....I got good at changing goodman parts😅😅
Your a good man 🤣👍👍
@@HVACRSurvival wonder what company that was..hmmm...notice I said "worked" for 🤣
Nice work on a rough job. Sooted HEXs are the worst.
Awesome video never seen that much black cardon on a rt every interesting
Over 30 yrs HVACR in Wisconsin... never come to a LP regulator that was set correctly ( all gas regulators need be set under 100% load). BTW York & Goodman suck both commercial and residential.
I did one of these today and two to do tomorrow. Awful design. It’s like they built the entire unit around the heat exchanger. Plus that pilot tube setup is crap. Always clogs up. God help you if you’re in a tight space….. just like you are. Hang in there! This is the HVAC life!
it identifies as a diesel lolll
Does the manifolds have all the correct nozzles for LP?
I’m trusting that my coworker did it the way it should’ve been done. There was no documentation left behind and it’s not our brand so I don’t have any information on it. Normally a sticker is provided with the orifice size number, and gas pressure, but neither of those things were installed for me to read.
Cheap people win expensive prizes… looks like they have the cheapest equipment you can get. And the pressures are going to fluctuate badly.
I feel like without those silly chimney things the units will run better.
the condition is in is due to them running the unit with natural gas orifices and gas valve spring,too much fuel,if converted a good brush and clean,good to go.well done.
Damn!!!! Thank God I live in the valley of dams. Cheapest electricity in the world. Gas scares me and that is way too much work.
😂😂👍👍
Always remember the three laws of thermodynamics.
It applies to every single thing you will ever encounter and not restricted to just our trade.
Contemplate.
Apparently what you smell in bad exhausts are aldehydes. Don’t quote me on that
You are correct.
That’s exactly what he smells is the aldehyde . If you smell aldehyde at a furnace, you most definitely have carbon monoxide (can’t smell carbon monoxide but absolutely can smell aldehyde , produced by incomplete combustion.).
Good call👍.
That’s an interesting word I’ve never heard before. It’s good to know. Thank you.
That heat exchanger was basically a chemistry lab.
This unit seems like a case of the customer playing stupid games and winning stupid prizes by cheaping out.
I hate that , specially inside buildings.
I normally pull the heat exchanger and wash it if its not too old.
Rolling Cole RICO
Wow that’s bad! I use the code at TTT.
Awesome! Thank you!
I always thought the York RTU’s were complete and total junk, the very little commercial work we have done were all Yorks. Don’t be a dork buy a York lol
🤣👍
👍👍👀thanks for the video
Thanks for watching!
That's about the best you're gonna do with it being sooted up like that. Gotta work with what you got, Nice job, Rick!
Thanks Steven!
Now I understand I've seen that color of flame in past I'm had mine like diesel smoke
Mm sooty, like them diesel trucks!
Those heat exchangers suck to replace.
That is some garbage but I'd derate the burner orfices. If you can find the plugs you redrill them right into the existing burner orfices. Not sure what your altitude is but in Colorado I had to do this in the past. It probably wouldn't hurt as I bet with that cheesy ductwork your temperature rise is probably high anyway. Just a thought. I have a orfice drilling bit kit with several sizes. I don't even know if they even sell this anymore as I never see them at suppliers selling this stuff. This trade really sucks, most would have said phuck it get a new unit. Ha, cheers to you and your efforts. I picked up my drill bits and plugs at CD Jones several years ago and haven't had to do any modifications in several years now. But it definitely fixed my problems with burning dirty! I had 500 plus ppm CO and after modifications 15 to 50 ppm!
According to the technician that was out there prior to me that did the conversion he replaced all the orifices with an LP kit. Surprisingly it’s been two months since I was out there and I haven’t heard of them calling in yet. When I went back to install the low gas pressure switch, I blew it out again this time with nitrogen and got the last bit of junk out and I open the air up more.
@@HVACRSurvival You still may have to derate the orfices if it still is burning dirty. It just is a long process. The engineers probably smoking crack! Ha
@@Paul-VanHorn 😂
It burns the eyes and nose. I can smell them just as soon as I turn the corner.
The propane is hooked up Wong should sucking vapor out the tank I think
1908 Time stamp! That was my thoughts. What was the COMBUSTION Analyse readings... TESTO,, If you aint TESTING,,, Your GUESSING
This garbage should’ve been replaced a long time ago and that’s what I told them. They bought cheap ass equipment and they had a shit ton of problems with it, but I can’t sit there and say that stuff in the video. They got what they paid for and they need to replace it. I’m not gonna destroy my analyzer when I know that CO level is probably over 2k ppm.
Add turbulators in the heat exchanger you may not be getting enough air mixture
What, the RTU doesn't run on diesel? Our bad.... LOL
Cool video but there weren't enough ads. I stopped counting at 20, you should have YT bump it up some more
I forgot to check. I usually only have 2 sorry.
They would have been better off running a propane generator with that giant tank, and getting electrically powered HVAC units.
I never knew a furnace could roll call
Roll out switch
I would consider this an HVAC job from hell lol
It felt like it. 👍
Gotta re-title the video something along the lines of a reverse Michael Jackson transformation😅 all jokes. This video really showed me how far you go as a technician and you do things the right way not the east way. Thanks!!
Thanks Isaiah, I was there all day. I had a tan when I got home.
😂 i bet.💪🏾
15:00 you can hear the amperage on tilt and dude puts his HAND WITH GLOVES ON in and starts grabbing at the rubber belt attached to that motor....bro if this isnt some of the most darwin stuff i've seen on the internet recently
And if you notice, I don't put my fingers on the inside of the belt if for some reason it would take off. Generally, they never do when they're locked up like they are.
Heaven forbid someone put registers on the spiral and step it down, let alone the exhaust extensions...
All tubes will soot up when not converted to LPG correctly
Carrier sure is not any better when hacks are involved
17:24 - you need to use blue electrical tape. ))) it will be right!
“Some ying yang “ 😂
