- In This HVACR Training Video, I Show How to Wire The TH, TR, and TH/TR Terminals on a Combination Gas Valve. I discuss the Flow of Gas Through the Valve Solenoids. I show the Common Wiring Methods. I show how to Light the Pilot and how to Power the Gas Valve. This type of Gas Valve is on Gas Fireplaces, Older Furnaces, and Boilers that run on Natural Gas or Propane. Supervision is needed by a licensed HVACR Tech while doing this as Experience and Apprenticeship garners Wisdom and Safety.

Can you give info on where to purchase retrofit parts for an old 1960's Reznor 55k BTU natural gas ceiling hung heater ? Want to retro fit gas valve, high limit switch and transformer parts?
You explain how it work very well Thank you
Thanks Andrey!
Fantastic channel. Current Hvac student and I feel I’m learning more from these videos than in class. The accelerated course is good for hurry up into the field but it leaves much out for actual learning.
You deserve EVERY like sir. Excellent channel!
Thanks a lot Jason!
Helpful video . I got one wire in the common terminal. But moved it to the right place and it solved my problem. Next time I will take a photo of the wiring.
I love these mini flame thrower demo's!
Thanks Tomon8tor and Hasan!
Love your book covering A/C. It is extremely well written and clear as a bell on every issue a person could ask for. NOW, write a book on gas furnace installation or at least troubleshooting various gas furnaces and I WILL buy it.
Another awesome video. You should be a teacher. You explain things very well. Happy Thanksgiving to you and your family. Have a good day.
I am a licensed teacher of HVACR, Sheet Metal, and Building Maintenance in the State of New Jersey, thanks Ray Ray!
This video rocks. My gas valve had the thermostat wired backwards; I couldn’t figure out why a new digital thermostat wasn’t working until after watching this.
Your video was amazing and your very good at exposing and breaking down everything thanks and very much appreciated
I appreciate that!
I swear you are like the best person in the world to explain this I love your videos keep them coming.
I am really glad that you enjoy the videos!
Excellent demo and explanation, as usual.
Thanks Kenny W!
thanks a lot for the great explanation
Thank you for all your videos and teaching keep it up bro
Will do, thanks ejohnfall!
all good, thank you ...
Thank you very much for another great video and happy holidays to you and your loved ones!!!!!👍🙏may God bless you!!!!
May The Lord Bless You Too Gilberto, thank you for your comment!
I love you man, Happy Thanksgiving to you and your family!
Ha ha, thanks JDT738126, thanks a lot!
I’ve worked in hvac for a little while and I recently received a nice ventless gas fireplace for free and it works ! But I want it on a t stat ! I’ve looked everywhere ! Thank you I think this will work for me I’m an electrician mostly lol so one lead from the transformer to the valve and the other lead from the transformer to the t stat for 24V I’m going to guess that lead goes to the RED on the t stat ?
Well...I just watched several of your videos and figured out the service tech that visited my business lied to me and I paid a $200 service call for nothing. Thank you for helping me diagnose my system via your great instructional videos. Please keep up the videos - thank you Sir! Off to have a little chat with the company now...
Great teacher!
You are very welcome.
thanks, partner for sharing! Happy Thanksgiving to you and your family.
Have a great thanksgiving Jimbola77!
Great video thanks!
thank you, very good video
Thanks mc20855!
could you make same video about honeywell VR8215?
We are trying to install a eco bee thermostat. We have an extra wire running through to the old thermostat that is not being used now and need to make it into a common C wire.
where would a person connect it too on here? We have similar TH terminals. Thank you
I am having the same issue, did you find a solution?
@@frhorntimmy yes I called a friend of mine that works on furnace’s and he told me to hook it to a back TH terminal but unfortunately I can’t remember which one it was. And my son sold his place so now I can’t even go down to find out for you. Sorry
My flame keeps cycling on and off and I narrowed it down to the position of the pilot assembly which kicks the flame on and off if it's not in just the right spot which I adjust by repositioning the stiff yellow, green and white wires going to the sensor.
Does the pilot flame sensor fail by producing insufficient voltage if it's not in the very hottest part of the flame?
Or am I just dealing with a bad electrical connection in the sensor?
Since this system runs on 24V AC -- that's AC -- how can there be a "hot" or a "ground" (as stated in your video) when the voltage is AC, where there's no such thing? My system uses a 24VAC step down transformer with a pair of floating output wires that are not hot or ground.
If you jumper between the two wont the gas valve open?
My pilot light has been off for approximately one month and cannot get gas to flow to the pilot. I have the same vr800a 1020 model as you have in the video. Should I use a torch to heat up the thermo couple and hope it sends a signal to the solenoid for it to open?
Hi there i have an old style gas valve the pilot stays lit but want light the flames i have 24 volts from my old 2 wire thermostatic i have gas coming in but not coming out to the main burner thru the valve please help.
Great video
Thanks gyver471!
can anyone tell me the model of the gas valve in this video? i need to find a suitable replacement thanks
So my pilot light stays lit, bit there is no gas flow. This is an out door heater that runs on natural gas. All but 2 light and work. Replace Thermal Couplers, thinning maybe it would fix it. It did not.
What if both 24 v wire are the same color not blue /red but yellow/yellow
So I need help wiring my Trane Unit heater to a Robert Shaw 712 series Pilot ignition system, I have followed the instructions included for the gas valve and ignition control, however it doesn't provide the wiring diagram to connect the wires from the transformer and the Trane unit itself, the transformer has 3 wires, a black, white & blue, the Trane unit has 3 wires also, red, white & black. Also would need the T-state connections. Any help would be appreciated. Thank you,
Hi just looking at your video. Where does the two wire connected at the thermostat?
Is it possible to use the DC low voltage generated by the thermocouple to power the thermostat, thus having a self powered appliance, which would not be affected by a power outage? In a set up like that, how would the common be wired?
You would just use a nonpowered stat or one with batteris. They cannot be powered with the dc millivolts, thanks
and you would still need 120 volts to power the blower motor and inducer...
I just replaced the valve on my heater and the flame is high, How do I adjust it?
can you connect one end of coil to TH/TR (connects to PV of ignition module) and the other end of coil to TR ? and the TH connects to MV of module? so TH/TR to TR for pilot gas. TH to TR for main burner? thanks.
I have an old garage heater, natural gas. Was in there when I bought the house. It has the similar setup as your video except without the safety device. Also has a fan in the unit. Have no idea what the brand is. I installed a heat only thermostat new recently. The furnace heats to temp then shuts down like it should but fires up every few minutes. Sometime just the fan starts and runs, shuts down and then it fires the gas back up retriggering the fan as well. Sound normal?
Hi , I extremely like your video .
Can you give me advise ?
I got not working VR8200A2363 .
After your lesson I found - pilot light solenoid is gone .
Do you know solenoid part number to replace old one ?
I have an old furnace.. which still works good
But the thermostat got broke and wires went inside the wall.. I’ve been trying to find a 120V wire or transformer but don’t look like there’s one.. just wondering if this set up would work on any gas furnace? Thinking about to buy all parts and make the full set up from the start
So the terminal posts sitting on the valve do not go internally into the valve and they are just posts and when remove their wires to measure resistance you get ohm infinity? And that means you could use any terminal label so why use TR or th so what are those stand for and why are those names used?
Reason I ask because I measured Th to TR 43 ohms? so I would think a wire should go into the pilot solenoid by way of one of these terminals internally for my intermittent spark s86f module. I already watched your s86f video.
So I'm thinking the externally wired coil is the pilot coil is 16 ohms since that's where PV connection to th/tr and returning on Tr. So the internal main coil which MV is connected to which is across th and TR is 43 ohms and is wired internally, although I can't see the internal wires.
does this valve works the same as those dual intermittent pilot gas valves that use with intermittent spark ignition module? i was working on a york RTU with two gas valves. the terminals on the gas valve were TR, TH/TR, TH. the TH/TR was connected to PV of ignition module. the TH was connected to MV of the module. the TR was connected to ground. if i were to measure from TH/TR to TR i should get 24vac to open the pilot gas correct? and if measured from TH to TR i should get 24vac to open main valve for burner correct? so does this mean this gas valve has two coils? one for pilot gas and one for main burner? thank you.
Great your vdo simple but lern more
Thanks Sajjan Lama!
Can u help me out my dean open fryer is not working
hey, partner does your channel show more video's?
If you are talking about Patreon, it have articles and some videos in the community and up category. I will be coming out with the book and other resources too soon!
WOW
The red wire coming from transformer going to limit swith does the other side of limit switch go to R on thermostat or W1? Or does it go to W1 then R coming out to gas valve again?
It can go to r to the thermostat, thanks
you are breaking your t stat with a thermo disc why not after the stat ???????????????????
Some older systems with combination gas valves, millivolt gas valves break the power before it makes it to the tstat with the safety. Obviously newer systems with relay controls and boards never drop power to the tstat so yes I know in that way it doesnt look like newer systems, thanks Rattler!
I was waiting for something to catch fire lol.
I have an off the wall question. I've been in the field for 5ish years and have always used fieldpiece meters etc. Is UEI just a personal preference or is there a legitimate reason why you would rather UEI over fieldpiece meters?
I have never used the product. All of my supply houses I use carry fieldpiece or fluke and readily available. So that is all I ever bought.
Those are the only 3 I would use. It was just what I started with and that meter is very inexpensive but great quality. I tend to use tools that new techs could easily afford and start off with so thats why, thanks!
When I let go the pilot The flame turns off
