You should turn on and Zero your Manomiter to the atmospheric pressure before your connection to the gas valve, and you should run the appliance for about 10 minutes at Maximum Rate to allow the burner and gas injector to become hot and expand to produce its true gas rate. You should always test all disturbed gas joints with Leak Detection Fluid after reconnecting any fittings, plugs, etc
Great video bud. The speed of everything was perfect and you explained everything amazingly. I just bought the same monometer and had no idea using it, I'm new to the field so this video helped out a lot.
excellent, well done actually & thanks for this. have you done a video for a tankless water system? We've got a propane tankless water heater that requires a 7/16" hose connector to the manometer. I've been give the WC stats: low -.06 and high -.07 with the gas inlet needing to be set at 12. Hoping to find a manometer online
Thank you for the video. May I know what gauge of your screwdriver to unscrew the adjustment cap on the gas valve? The cap seems very tight on my gas valve, and I am not able to unscrew it using a regular flathead screw.
I would think you would also want any other gas appliance (hot water heater , stove, gas FP, etc.)on and running at same time you are testing this valve?
First the video was great !!!! I have a question !!! When a heater ( furnace) first starts the burns turn on and after it reaches a temp in the heat exchanger the blower is suppose to turn on !!!! And after the heat exchager reachs set temp the burns stop the bullers keeps working till it cools the heat exchanger and start all ove4 again . Right. !!! I have a furnace that the blower turns on and a little bet after the burns turn !!! Which i think is wrong !!!!!! Trane / America standard model S8B1B080M4PSC. Any ideas
Out of curiosity why does the gas valve go out of adjustment? My mid efficiency never had that issues but my current Ameristar is a pain - gas valve always over 4 inches water column. Anyone help??
I just finished my new 2lb system last night. I had to adjust my maxitrol valves because they were factory set for natural gas at 8wc. I hooked up and turned the system on. Got a inlet reading of 8wc then adjusted to 11.13wc within the range of 11 to 14 for me. Then flipped the gas back off and checked the manifold side. Found 10.03 for high fire and 5 for low.
You would check the voltage at the gas valve when the board sends for gas to be released at the gas valve. If you have power there and the valve don’t work. It’s the valve. If you don’t get power at the time of the call, then you have a bad board
For a person here with very little knowledge, this was very helpful. Thank you!

Is it a fluke?

Perfectly explained.. great job!! Thanks for sharing Master!!!👍👍👍👍
simple clean and informative. Nice work.

Yes for pressure switch test! Thanks
You made it sound very simple, thanks!

Great Explanation enjoyed .
Awesome video..Your a good teacher. 👍
Very well explain! great video. Thank you for sharing
thanks man, this helps me out a lot
Great video, well done
great information brother
Great video keep up the good work 👍
Great video. Thank you.
Shouldn't you zero the manometer when it's open to atmosphere not when you are connected to the gas valve?
Great Vid. Thanks!!
Great explanation! One thing that should be mentioned is derating a furnace at higher altitudes
It’s also good to mention that pressures need to be adjusted to match certain altitudes
Please explain how. I want to learn. Thank you.
The panel on the furnace or the manual may have the derating values
Excellent!
Great vid thanks going to invest had a static pressure problem today thought it was the indoor tub turned out to be a damn return filter 😂😂😂🤣🤣🤣
Thanks you’re very helpful
Awesome thanks for posting do you have one for the inlet pressure?
Thank you man
Awesome man thanks!!!
Your pressure was high at the start but should you adjust the pressure to what the furnace needs on the spec sheet?
Hi, thanks for the great video. I’m curious, What are the downsides to having too much water column entering the unit?
Too much means it will burn very rich and can also cause the furnace to over heat
Great vid🎉
Great video
I would think you would also want any other gas appliance (hot water heater , stove, gas FP, etc.)on and running at same time you are testing this valve?
can we use manometer for some corrosive gases like vehicle smoke exhaust

Great video, how about the inlet side?
Use adjustable wrench on brass fittings had 2 different instructor that would lost it seeing channel locks on brass fittings
Thanks my friend for your tips.
Any time
Thank you.
Do you set the pressure based on the gas valve or on the pressure recommended by the furnace unit ?
my manometer doenst jave the INWC setting.what should i use?
Where do you get the screw fitting for that connects to manometer hose
I have a Honeywell gas valve VR8205S2353. I don’t see a place on the gas valve to connect with the manometer. Please help. Thank you.
Great vdieo
Where can I get that plastic attachment with that fitting?
Good video
Mine came with clear and yellow hose… does it matter which I use?
Out of curiosity why does the gas valve go out of adjustment? My mid efficiency never had that issues but my current Ameristar is a pain - gas valve always over 4 inches water column. Anyone help??
My manometer doesn't have P1 it has + and - which one do I use to check WC?
if you set it to 3.5 and keeps going up alot after you adjusted to 3.5. can it be a bad gas valve?
Yea
Great video, but what about the inlet pressure? Also Please do a video using the pressure switch tester.

If using LP gas, what should the water column be at AFTER the gas valve?
Usually around 10” w.c. But some manufacturers are different. You would have to look it up online to know for sure
what valve is it?
What settings does the manometer have to be on to read W.C.?
On my meter, it says inH2O
No pipe dope on the barb fitting that you put in there for the hose?
no
I need to know WHEN you need to check the gas pressure.
What should the w.c be for the inlet
Between 7 and 15
How can you tell if it's the gas valve that's bad? Would it not turn the furnace on?
You would check the voltage at the gas valve when the board sends for gas to be released at the gas valve. If you have power there and the valve don’t work. It’s the valve. If you don’t get power at the time of the call, then you have a bad board
@@HVACTechTips I appreciate it thanks
"pap dope"
Kentucky accent.
Lol Georgia!
Clock wise or counter clock wise?
CCW will turn down the pressure. CC will turn it up
Do you have a email I can ask question at
Yes. It’s hvactechtips1@gmail.com
You forgot to.mention where to set your manometer to
