Thanks for the video help. My main burners wouldn't stay lit. I suspected the thermopile but the voltage checked out - I would never have known this if it wasn't for your help. Turns out the thermopile's elec connections to the gas valve needed a little cleaning and tightening. You saved me at least a couple hundred dollars. I owe you a drink - cheers!
i have a Earth fireplace insert. I set the valve to Pilot but the pilot will not lite at all, No gas is going to it. The gas is on feeding into it. Why do you think no gas is getting to the pilot? thank you
What if I dont see half the millivolt reading with switch turned on. I get 550 millivolts with pilot on and switch off but only about 5-10 millivolts when switch is on.
Same with me. I've come across a forum post where somebody was getting low milivolts all the time and after they cleaned the thermopile it returned to good milivolts, but theirs still wasn't lighting. Then they replaced the thermopile which fixed the issue (even though the millivolts on the thermopile were good after cleaning it, it seems theirs was still defective)
Since their thermopile dropped to 50 mV when the switch was turned on. And a reply was: if you have enough power to maintain the pilot, but the main valve draws too much current, it is most likely the gas valve. But I would go for checking the connections first, (no cost for parts) then replace the thermopile, (less expensive than the replacement valve). If that does not work then the valve. I always ask the mechanics that worked for me when the condemn an expensive part... "After you replace that and it still does not work, what will you check next?" they usually suggest some less expensive repair, then I say... "Do that first!" This brings me to the conclusion that the pilot may not be large enough to generate the necessary current. Is the Pilot Burner Clean?
Usually that’s the pressure adjustment screw underneath the brass screw. At least that’s what every single furnace/HVAC gas valve adjustment screw cap looks like.
No fluff, just the facts...this is a very clear, concise and helpful video. Thank you for posting it!
I like the appearance and features. Perfect addition for finished basement.

Exactly what I was looking for!
Thanks...
Have been watching some pretty bad videos on this subject. This one is the best.
EXCELLENT GAS VALVE TESTING METHOD
i have a Earth fireplace insert. I set the valve to Pilot but the pilot
will not lite at all, No gas is going to it. The gas is on feeding into
it. Why do you think no gas is getting to the pilot? thank you
Awesome video. Thank you!
Thank you. Great video! Great information. Useful. Thx
Very to-the-point and informative. Thanks!
Hi, how would you adjust the output gas pressure for this valve? Is there an adjustment screw somewhere? Thanks
Great Video
Great info- and you obviously know what you're doing! Thank You
best video i can find on the subject Thanks
Where did you get that rubber fitting that goes over the in and out? I need one bad!

Did you get an answer for this this is the behavior my valve is doing after replacement the fireplace does not turn on

where did you purchase the gray 1/4" ID tube adapter you show connecting to the pressure tap? Thanks

Whats the large brass knob with the slot in it next to the pilot knob?
Usually that’s the pressure adjustment screw underneath the brass screw. At least that’s what every single furnace/HVAC gas valve adjustment screw cap looks like.
The only I cannot check is the gas pressure... The flames are weaker than the pilot, all the other stuff test okay
