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.

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.

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

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

Rick i hate working on LP furnaces especially when they are not commmission properly. Great video Rick!

This unit seems like a case of the customer playing stupid games and winning stupid prizes by cheaping out.

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.

Good repair for what you’re working with.

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.

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!

I hate that , specially inside buildings. I normally pull the heat exchanger and wash it if its not too old.

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.

@HVACRSurvival

Come to find out it wasn’t a liquid to vapor regulator, and those two tanks provided several other buildings with gas.

@@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.
