Adjusting Gas Pressure on a Standard and Gemini Furnace Valve

[@Barracuda48082]

Glad to see all are still kickin and healthy. As always your smart shorts videos are welcome and much appreciated. keep them coming. "Never stop learning. "

On the Gemini valve, has the port that hooks to the burner box. Perhaps a follow up showing folks the proper procedure on a sealed combustion furnace where you’d t’ into and reference the burner box in making your manifold pressure measurement. Great video!

[@deanburke3041]

Yes. T into the sealed combination chamber for reference to the valve displacement pressure. Otherwise off & way inaccurate.

My teacher and I we're dealing with a new piece of equipment. It was over firing and I caught on due to a small "smell." Come to find out the outlet pressure had needed adjustment. We ended up pulling the manufacturer instructions just to ensure proper leveling. This was a Goodman unit if I'm not mistaken. I did completely remove the set screws. I guess from watching this video we don't need to completely remove them. Although I don't know how I would've inserted the tubing adapters. Long story short I ended up getting the outlet pressure adjusted properly 3.5" W.C. for the unit and adjusting some DIP switches just to be sure other functions were set right. It was a fun experience and reminded me once again to ensure to have the manufacturer instructions accessible also to have a good manometer. Thank you!

A great video as usual but I would like to go over a few things not mentioned #1 Inlet pressure is to be tested for minimum and maximum proper working pressures, this should be done with all the gas appliances running at once to ensure proper fuel run sizing and Gas Utility Supply ( note: the running of all appliances is not required for manifold pressure adjustment as long as the incoming pressures are within standard . Varying loads ,on & off should have no effect on manifold pressures at any time).#2 your video showed no sediment trap (drip leg) which is required by GAMA & the national gas fuel code. Also note the drip leg is another great place to connect a manometer for taking Inlet pressures. Hope some of this information helps & you all stay safe out there.

Inlet pressures vary by altitude. All that matters is that outlet pressure stated to run the burners, and the mixture.

@@deanburke3041 , the diaphragm design on Regulators is what compensates for altitude & Inlet pressures. Dean, I'm sure you're a happy guy when 3.5" water column is consistent on your manifold but it might be nice to understand how we got there ( from the Wellhead to the gas Appliance). There is a lot of engineering that takes place before we get to your 3.5" manifold pressure.

[@deanburke3041]

@@boby115 I guess. The diaphragm is used for birth control also, but it doesn't always work.

[@boby115]

@@deanburke3041 , the one for gas regulation doesn't always work either ( providing me a 35-year career in the gas utility industry). Stay safe out there and keep learning.

I’m on the exact same chapter in school. It’s like you knew I needed this video lol thank you

Sod off done it myself. Saved thousands. Goodvid.

Thanks for posting this valuable information! Can you advise one my problem? 2 years old Goodman furnace , not igniting sometimes, tried change igniter , clean flame sensor, filter , control board , no error code, worm weather ignite , cold weather not, when not igniting, I turn on off switch for 10 to 15 times and finally igniting, once igniting, it works fine , but after idle for 10 or 15 hours furnace will fail to ignite, then I again turn on off furnace switch, and ignite, please advise if you can! Really appreciated!

[@kyleh1974]

Reminder on Gemini valves, don't ever use the on/off switch on the valve itself. Too often they won't reset then you have to replace it.

1st time happening to myself yesterday. 🤦🏼‍♂️

[@dylanvillano5317]

Thanks Bri, You're the guy! 😊

[@jamservice1046]

Good job ❤.

[@CHIBA280CRV]

Very informative thank you 🙏

[@eduardoacosta2315]

Thank you so much for the video Chris 🙏.....💯

[@channelcatchaser9426]

As always great video

[@shevygill]

that's a very good video

I use 5/16 maple sap line it like surgical tubing. Maple syrup supplies. It's the barnyard soloutions.

Brian, nice vid, however I think it’s YELLOW JACKET , not sure has a MECHANICAL gas pressure meter, but on a service truck, it sucks, I have 2 manometers , 1 ‘U’ ‘TUBE & 1 DIRECT READING , some years ago, my heat ( steam ) cool in the morning, put my glass kettle on stove , to boil for drip coffee, darn it took forever, then noted a STRANGE FLAME , RED but it went up & down, So checked my gas pressure @ my inlet for gas valve,,, 1/2” inlet , OH OH , called my utility, he could NOT BELIEVE IT my piping was from the days of MANAFACTURED GAS, , there was NO SUT OFF IN LAWN, NOBODY on street had one , so they dug 10 feet down, on other side, they removed the connection, changed the valve there then ran a plastic coated tubing, installed a lawn SOV, the tubing went to a DRESSER COUPLING to connect it to the meter, , then we had 7” inlet then 3.5 manifold pressure . No problem since, but the reason for the weird flame was that large old pipe had so much crud in it, was retarding gas flow .. but I still love my manometers ! Cheers 🇺🇸🇺🇸🇺🇸🇺🇸

[@andym9199]

There are differences between natural and propane gas pressures. This should be noted.

[@MindKontrolleProject]

What would cause the outlet/manifold gas pressure change over time?

[@wdxwm300]

My valve shows 3-5 Range and 1.2 FX wondering what thr FX stands for

[@frediszamora3800]

👍🏻👍🏻👍🏻

[@jesuspineroarzuaga9821]

Thankssss

[@ironjohn5914]

Why not just install the new digital valve

[@deanburke3041]

Makes it too intellectual. Adjust the pressure up or down to spec. Sounds like a classroom teacher would talk about it with no experience. Too didactic.

[@deanburke3041]

See how the burners run too!
