Measuring & setting Gas Pressure using a manometer

[@mattro4902]

As a novice to mechanical service, this was very helpful since I've never used a manometer. Thanks!

[@retsbew8954]

Great video. New subscriber. I would also add that you also need to clock the gas meter. The gas company should provide the quantity BTU heat content of 1 cu/ft of gas provided. You should also factor your elevation for your equipment location to set the gas pressure. I would love to see a video from more technicians on the process. It seems very few people do it. Thanks for the video!!

very good description of testing gas pressures. thank you

Hello from Brazil, great and valuable explanations, thanks a lot!

[@mechanical-hub]

Glad it was helpful!

[@drohvac4583]

Are you gonna make a video for manifold side or dialing it in or fine tuning while or during combustion test to make sure those combustion numbers are right?

[@bchrisl1491]

I read there should be gas flow when setting the pressure as the cutoff pressure will be up to thirty percent higher than the operating pressure under flow.

[@tzvifeldman]

Great video. Aren't you supposed to run the run the appliance with the gauge hooked up so you can tell if there is a pressure dropps to low while it's running?

[@mechanical-hub]

Addressed that in the video at the end

[@boby115]

@@mechanical-hub , you did address it at the end of your video but @tzvifeldman is correct. The working pressure (pressure with the unit running ) is the most important pressure and your regulator adjustment should be made at this time . After setting your working pressure then you should note your lock up pressure ( pressure with the unit off & making sure you do not have a creeping regulator). I’m not sure if you made another video on the proper set up and working pressure on adjustments for the 2 pound system which should always be done before the pound to inches regulator set up. You did a good job on your video but you really need to start making those regulator adjustments with working pressure . My expertise comes from 35 years in the natural gas industry and in my retirement I still consult when incidences occur in our industry. Hope some of this information helps and stay safe out there.

Good explanation. Relates to a generator I am having installed.

[@jeffrice8620]

Great instructional video!! Thanks!!

[@tannerpalacios9466]

Great video 🔥 ready for part 2 😎

[@cosmolee7902]

So, this is just measuring the pressure at the inlet of the valve. What about the outlet? Suggestion: If you show measuring outlet pressure in another video, you should have a link at the end of this video so it can be easily found. 😁 Otherwise, good video.

[@funtime-gq8ju]

Awesome explanation buddy help me a lot

[@jrokruhlica]

Thank you! Love the content, thank you for the pertinent information and demonstration. Not related, do you do cross connection testing as well?

Lots of good info there. Thanks.

[@johnleny5662]

Hello - thank you- this was an informative video. What model Combi boiler are you installing that has a self adapting gas valve?

[@SonOfSpock]

Great video! Did you ever post the follow up video for the output pressure?

[@Mik-mk8us]

Hi . To calibrate the WR 2 stage valves . Brand new. To Lp. The digital man meter I have has 12 unit codes . Which 1 do I use to set the manifold pressure . Psi _pa _ bar_ mbar ?? I'm so confused

[@gmatthewclark]

Hey Eric, Do you use your digital manometer for your manometer test downstream of the regulator? Here in Ontario we need to maintain 10” for 10 mins. I find the digital manometer I use will “creep” while my analog doesn’t. Have you run into this?

[@mechanical-hub]

Absolutely. Our final gas test is a manometer test, simply showing a leak free system. I always use my analog for that. The problem I see most often is the appliance gas valves leaking by. I either use my analog or isolate the appliance if the inspector is okay with that. Most inspectors in my area know that the gas valve will show a leak on the digital manometer.

What is the PSI normal of a Residence home? Commercial building?

[@unknownbostonian]

Thats 2 different questions with sortive the same answer. It all depends on kw per hour and that then is translated to btus needed.

[@JMDPhotography-Chi]

In my area the gas utility delivers either 7IWC or 2PSI

[@mlc82]

where does a plumber take a certification course online for manometer

[@donf3739]

Do you have to test the inlet pressure on the gas valve like that, or is the pressure the same all the way between the regulator and the gas valve?

[@CarolynFalls-g2x]

If my boiler squeals and then shuts off when I turn it on, could that be the gas pressure?

[@dzw4826]

I'd be concerned that your two units are giving different results. The spring loaded analog gauge requires frequent calibrations. Perhaps it's overdue for a calibration?

[@boby115]

DZW, that’s why we always use U tube manometers in the gas utility industry , trial attorneys could never argue about the accuracy and calibration.

[@scotthale4857]

Very informative. Thanks.

[@rosstaylor4924]

Hi Eric Great video👍 Do you guys in the states use a U gauge when working on gas? They are quiet common in the uk aswell as digital manometers.

[@rowdynoe9595]

Is this a propane combi-boiler? At least for tank natural gas water heaters the gas control valve has a built in regulator that can be adjusted, only installed a few tankless water heaters so I am not familiar with them. My master plumber never mentioned to me about testing gas pressure, but I do remember reading that youre supposed to do it in the manual😅

[@mechanical-hub]

Tank water heaters do not have a regulator built in. You are still required to verify proper gas pressure, just as you are for literally every gas appliance.

[@mikeglasgow9618]

You did mention that this was the only gas appliance in your shop. Maybe should have just touched on dynamic pressure for the younger techs. I think I would have dusted of my old Honeywell Liquid Manometer to SHOW what an inch of water column actually means. Not to go into a 45 minute dissertation. But only touch on the subject and let them know that there can other factors involved IF... working with other appliances on the same regulator. JMO
