New Trane S9V2 gas furnace gas valve setup FAIL inducer limit

[@kenthomas4668]

I watched an earlier video of you setting up that furnace and really appreciated it. I was over reacting after reading the instructions which made it seem much worse than it was. Watching you relieved my anxiety and it was a simple set u by putting it in test mode.

[@TedCookHVAC]

Thank you very much for watching Ken.... I really appreciate it !!

[@josephlopez3278]

Great explanation.on water column.on pressure switch and limit..agree with you on testing heat/ cool on installs.and all specs.,but installers have there own minds.here in Texas anyway..

[@williegillie5712]

Enjoyed the video. I’m surprised they didn’t check the gasses before they called it good. With that much pipe it’s bound to affect the pressures. No harm done just a few adjustments and a hose reroute. All in a good days work.

[@davidbleil9934]

The 120v supply wiring is not even close to being up to code. Looks like a DIY wiring job there. The manual for that furnace says to set high fire first then low fire due to the low fire regulator being after the high fire regulator in the valve. That is why high fire adjustment effects low fire.

[@brianellsworth4767]

Utility rooms should be a building code.

HVAC talk: "I'll just blow this dirt off with some nitrogen, and then head to the basketball game." Town talk: "Look, Ted Cook just came in and he looks like he's been crawling in the mud under someone's house, and then came straight to the game." Hi Ted.

[@TedCookHVAC]

What’s that about ??

[@rodgraff1782]

I like those little cases. I just bought an inspection camera with an endoscope and it came in a cardboard container. This would be perfect for it.

[@HVACinSC]

Hell yeah Ted! Those little cases work really well for the price! Thanks for the shout out brother! Good work as always!

[@TheWoodman064]

Great to see you test the gas pressure. A lot of winter issues are with that even here in California! B.l.t.n64!

[@RJMaker]

Great video thank you. I would say the installers either need to get a LOT more training or need to be let go. Not setting the GV pressure is only one of many issue I see on that installation.

[@pauldusa]

Just my guess. But the high limit would not trip in low because it still would be in spec in high. Since there is only 1 circuit inline with the high limit switch

[@MarkJones-no2zf]

How did you get that electric connection past inspector

[@ronwade5433]

I was the night houseman in Sun Valley, ID, real snow country. Tell folks why the gas pipe dropoff is important. Hold my volt meter.

[@NorCal-refrigeration]

? Isn’t there a minimum distance before you can 90 out of the inducer. Or is it different per brand.

[@throttlebottle5906]

ideally minimum of 3x pipe inner diameter length before long radius ell. but it's likely not specified on most and many have placed sharp 90's inside for years. I'd think more like some kids(rodents) were playing around blocking it or the pitch is bad and ice forming at the outside blocking it, maybe compounded by short cycling or just bad from the start chinesium component ;)

[@sknight0391]

"I'm just a heating & air guy." It sounds so bad when you say it that way Ted 😂 And yes I totally agree. Every gas pressure should be checked and set and the gas valve marked,with a sharpie, what the gas pressure was recorded as. And a temperature rise also be done in the ductwork to make sure it's burning within parameters. 👍

[@TedCookHVAC]

May as well be pulling hind teeth from an alligator !!

[@sampantiliano]

If my guys left that furnace like that they would have some serious problems with me. Just because it’s under a house and the customer won’t see it doesn’t make it right to do things incorrectly. No switch plate no romex connector

[@hozerhvac4406]

Good video Ted , This is a good opportunity to get your guys to use Measurequick on all new installs. It’s a good way to commission the unit and hand in the report on each installs. It will get them use to checking gas pressure , static pressure and correct inputs.

[@sergiodjf]

That furnace was probably started up on a Friday afternoon 😂🔥

[@Guillotines_For_Globalists]

That romex insulation was just a tad too short.

[@ryangreen587]

I saw that also

[@mannyjr2912]

Why do you not like the two stages of heat?

[@cathyb2601]

Why do you not like a 2 stage thermostat for heating?

[@markhoffmann5941]

@D B you jumpered the w1 and w2 which in effect is the same as using a single stage stat. Then your comment above states; never use a single stage stat???

[@markhoffmann5941]

what size diameter is that gas flex connector?

[@MrDmadness]

@D B w2 is the second stage relay connection. The 2nd stage is part of the design parameter and as such if just as efficient and provides the same condensation latent heat recovery. Combustion analysis proves this.

[@MrDmadness]

@D B elaborate as to what you refer too. W2 is the 2nd stage, this is a fact. I have yet to see you do amcombustion analysis so you base your assumption on what exactly ?

[@MrDmadness]

@D B simmer down buddy. I have watched some of your videos. Have you ever done a combustion analysis ? Because what you are saying with regards to the efficiency is not at all true. Since the volume of air movement when the high fire mode is energized also Increases you will not lose condensation, this is why if you did a temperature differential testi on that same furnace tou would note that the accepted differential will fall very close to the same as in low fire. For the record A class gas fitter here. Calling me an idiot when you post a video and then make false claims about things you claim to understand well is ridiculous, your reaction suggests that you are well aware of this discrepancy weather consciously or sub conciously. ;)

[@Mahigeer1]

The electrical work needed improvement. Longer Romex, strain relief connector, and cover on the switch box. I have also notice a lot of labels on these units. Lastly, doesn't factory connect the hoses and set the proper pressures on valves?

[@Tc-gt5vm]

Need some coveralls for pre game crawlspace adventures. Thanks for the tip on the pressure switch hose orientation. Peace

[@MrDmadness]

Dont like 2 stage for heating? ... you do not live in Canada.

[@Slavelife9279]

You guys don’t test new furnaces with combustion analyzers? It’s the only way to really know what that furnace is doing, 1.7 and 3.5 is what the manufacturer sets it to because they don’t know the application-duct work, flu etc. most 90+% furnaces I test are only in mid to low 80% efficiency range, this means the customer pays more for a furnace to save money but saves nothing!!

[@superiorcomfortheatingairl3373]

I have never seen you with a tool box of any kind, it’s always a Fieldpiece Voltmeter Pouch, Wire Strippers and 8-1 Screwdriver

[@TedCookHVAC]

Don't forget the fingernail clippers in my pocket and the jumper wire clipped to my belt loop !!

[@throttlebottle5906]

I'm starting to see his way and liking it.... after loading and unloading 500+LBS of tooling all the time ;)

[@r.mccullough6197]

Great video as always Ted....enjoy the game

[@aaronbrandenburg2441]

Did you notice that on that cut off switch for the furnace AKA the light switch toggle switch there was no cover plate.

[@throttlebottle5906]

didn't catch that in video, but likely that was pre-existing work they didn't touch and used same whip/wire that was there.... not saying they shouldn't have put a plate on it ;)

[@rb3263]

Great videos, great skills. What are your thoughts on using a combustion analyzer?, do you have videos using one?

[@amunderdog]

Realtors do not care for my type much. I start my home tours at foundation, Crawl spaces, utilities. They wish i would just look at the shiny new stuff, someone used to mask the actual building.

[@craigbraswell4269]

Hey ted, I was just wondering why you don't like a thermostat controlling 2 stages of heat? Have you had bad experiences with it or customer complaints? Just wanted to hear your take on it.

[@SpookyMDB]

I noticed that there was no drip leg on the gas line

[@BBYERS27]

Hey Ted how many installers do you have working for you? Service technicians? Good job getting them back up and running

[@capelookouttuber2854]

Attention all DIY, the holy grail with Grand Opening on 1/25/2019, Morehead City, NC of latest Harbor Freight store, see ya there Ted !

[@TedCookHVAC]

LoL

[@rodgraff1782]

Why sell a two stage high efficiency furnace, and then cut the efficiency of the system by installing a single stage thermostat? The longer the cycle, the more efficient the process becomes. You may suffer a little on comfort or recovery time, but makes no sense to me to not use all of the energy savings advantages. With that incoming pressure drop on the gas line I would be concerned. That gas flex connector could be the culprit. Having 10” static pressure at the inlet is way over what you should need. Our utility won’t set it over 7”. If the line is sized properly, it will work with 5”. Maybe the gas utility has the wrong size office in their regulator.

[@throttlebottle5906]

because most will fire at low stage for XX minutes then if there;s still a call for heat, go to high fire until satisfied.. thermostats are the worst device for staging IRL, garbage as they can be products, half the time the thermostats don't even work. too much electronic based junk anymore, chinesium filled homes and life.......

[@ronniehvac653]

Leaving the jumper on the board has always been my worst nightmare. Thank God I have never done it yet. Also, what's the maximum LP manifold pressure?

[@kenthomas4668]

did that once, little old lady called said it was, 90 in the house!

[@donnierobertson3088]

Good job

[@rogerkennedy8849]

Looks like squeaky floors in the future and buy your installers a gas pressure guage

[@throttlebottle5906]

alternately, look for intake/exhaust restrictions and check motor RPM, possibly tight bearing wrong winding and it's hardly making the switches which could overheat the safety. second to that is the indoor blower running and airflow at acceptable pressure drops? the fools close all the vents upstairs? poor ducting? no airflow over HE's = blazing hot gas temps out inducer. takes me a while to think sometimes ;)

[@throttlebottle5906]

too low of incoming gas pressure, regulators in the valve don't work well that low, I'm betting it may go too low or whack out if other things in the home are gas and turn on. it could even go so low the flame migrates into the heat exchanger and cooks the t-stat/fuse and short cycle.... the pitfalls of sparktronic junk, never seen those issue with natural draft vertical units :)

[@throttlebottle5906]

right after commenting, you said no other appliances, so regulator issue at meter, undersized feed, someone globed pipe dope into the fittings/pipe ends, flex connector undersized(seems that way by video) OR they didn't purge the lines and crap is now sitting in the gas valve inlet screen, no drip-legs visible........... yes I may have done that in the past once or twice ;) live and learn

[@MrDmadness]

Natural draft appliances also are about 65% efficient at their best, so you are tossing money out the window. Spark ignition is not as complicated as people think it is, this comes down to a basic understanding of electronics which the majority of people lack.

[@jkato3706]

Nice case I have the same case but I keep my filedpiece 460 so they don't hang on the truck all the time since the hooks always came off on those

[@a-youn9657]

Are you close to Myrtle Beach.. if so I always go for vacation with the family to myrtle beach and I would like to do install for you at no charge. Than you can post my install on your video .

[@TedCookHVAC]

jose marchante Greenville is 4 hours northwest of myrtle beach... I vacationed every year there as a kid. The change out you offer to do pays about 500 to 600... you don’t have to do it for free and yes I will video it.

[@lee-johnson]

Well! Who won the game?

[@TedCookHVAC]

Close but we won 59 to 55.

[@markbaker1969]

Ted have you had any luck getting those Smans shipped from your giveaway yet?

[@watermanone7567]

Good video. Do the installers have a check list to go thru and record all necessary pressures, voltage, etc. Also the supply wires are missing the outer jacket of insulation before going into the unit. Installers need to look things over before leaving. Thanks

[@MrDmadness]

Yes all installation manuals come with a final checklist. The non insulated wire you speak of is likely a ground. Often the ground will be un insulated

[@wegerheatingandair7458]

What manometer (spelling?)is that your using?

[@MrDmadness]

Fieldpeice

[@androslive]

Left my jumper on as well a few weeks back. On a Friday night. The on call tech called me after going there at 11pm to let me know he got my jumper 😣 whoops

[@rheidtech]

Great video

[@throttlebottle5906]

forgot the jumper on LMAO :)))) if I had a "penny" for every time i hosed up in my 41.x years of life, I'd be a multi billionaire....

[@kangaroogod]

Great job

This Law dates back to 1940’s. It has to do with getting paid for every minute worked. Employee screw ups are just the cost of doing Business. Nothing more, nothing less. Turn the volume down. You can’t change the law!

[@kskrawler]

Is it just me or does it seem like your installers make a lot of mistakes and forget a lot in installs?

[@TedCookHVAC]

2 or 3 out of every 100 we will find mistakes etc.... not a bad statistic for our volume of change outs.... always looking for perfect installers ... do you believe there is such a thing ??

[@georgiemac3662]

So question for you. So I bought a house that was required to get a new furnace installed before finalizing, this was back in 2017. My question is how long do I've have to wait till it's time for a maintenance, or is there even a service required??

[@special_k-hvac]

Manufacturers generally suggest annual inspection.

[@iLikeC00kieDough]

As a service tech, I think biannually is sufficient. Once it’s 7-8 years old, I’d have it checked annually.

[@joeskittino6659]

I am the greatest but I don't put a gas shut off nor a drip leg nor wired it with anything near safe and probably don't have a service disconnect I let my installers hook it up and run without testing anything at all. But I am the greatest because I could come in behind any worker and find flaws

[@MrDmadness]

From what I've seen so far on this channel ( and as an A class gas fitter and red seal plumber ) I agree with your assessment here .
