The resistance check guided me perfectly on to identify a faulty pilot burner solenoid (which I then swapped out avoiding the need to change the entire valve) on my Ideal Classic 350 boiler - thanks guys superb video - you are total life savers!!!

More of an installer myself but I've really enjoyed watching these boiler fault videos. You've taught me alot and put it in a way easy to understand!

One of the most comprehensive and informative pieces of content I have viewed. Thanks a million guys.

Roy is a great trainer on these gas valves, he explained the working process and test to perform to check serviceability and integrity.

Fabulous!!!. How I wish you tube could have been around 20 years ago from the point of view of referencing and refreshing previous training👍👍👍👍

Awesome stuff Roy and Allen. The more you teach the more you learn, the more you learn the more you teach. Thanks again for sharing, It is definitely caring 😎.

Really helpful! I find having this level of technical knowledge about individual boiler components makes everything easier, especially when diagnosing faults. Thanks for another great video.

Amazed what we forget,. Alan big thumbs up for u reminding us, and big thumbs up for our kind , who spend time to revise.

Roy's a great trainer, seems to have a great way of delivering a great lesson 👍Thanks for sharing allen.

Awesome yet again. Thanks Alan, Roy taking the time to do this

Another amazing video guys really helping the transition from installer to breakdown and servicing!

Thanks allen and Roy, its just great to simply understand those different resistances due to the voltages . as with alot of stuff its easy when you know it, but sometimes your too busy to stop and look.apreciate the vids

Outstanding guys, you always excel yourselves. Massive Thanks to Roy, Allen and the rest of the fantastic Allen ♥️ team 👌.

wow :) omg thats the way how i was learning about the boilers about 17 years ago:( now im in the Spain and spanish service manual reallllllly poor :( am still digging in english service manual... ps. thats the best film about gas valves THX for you're work

Must say hat off too you sir. Wonderful video and thank you for sharing. Regards from Ireland 🇮🇪

Top man Roy excellent video very informative 👍

Great one to Roy and Alan I've done my breakdown course with Roy at Baxi lots of knowledge

excellent presentation. very easy to understand. Thank you both

First class no nonsense, thank you

Thank you for your time and effort in making this video.

Great Video as usual guys. Many thanks for putting these together.

Another great video Allen keep em coming

Well done good video useful information thanks

Great video, very informative and well delivered. The issue I find is actually finding resistance value information to be able to complete the tests. What is the best way to get the numbers? You would think every manufacturer would just put the values for each component near the front of their manual so it's easy to find. Thanks Gents.

Thank you for sharing Allen. Great advice.

Another excellent video guys. Keep them coming Very informative. cheers

Excellent video Roy. 👍

Great stuff.

Great video

Great video, great Channel and two legends 👍👍

Brilliant video, keep um coming.

Great video ,very informative, keep up the good work.

thank's a lot ! great video very helpful.

Absolutely great video

You guys are stars!

Brilliant video - that guy is brilliant 👌

Excellent video. More close-ups please when you do the next one.

Fantastic video. Spot on lads.

really helpful appreciate vids thanks

Welcome Allen! I want to know if a Westen Star Condens gas boiler is the same as the Baxi Duo-Tec! After cleaning (acidifying) the Al-SI heat exchanger, the "Automatic calibration" will start, but after ignition it will throw away the flame! There's a new electrode in it! The videos are very helpful, thank you!

Thanks again Roy and Alan, very interesting to see the evolution of the gas valve and some of the pit falls in testing them.

Really good video and very informative 👍

Thanks Allen & Roy, very informative. Perhaps some close-ups on the pins testing would be useful?

Hi Allen , this video is fantastic , and informative and Roy as a way of putting it across brilliant please keep theses and other video's coming .

Thank you very very very helpful

Thanks a lot! Managed to pinpoint a faulty coil on the EV2 of the STS 848. Are there any instructions on how to replace the solenoids on this model?

You need to trademark “Me names Allen Hart” luv it when you say that❤

Great video roy

Great video, thanks so much

Excellent video.

Excellent video!!

Hi Roy does the second gas valve work the same way as the zero governor. I thought zero governors were negative pressure due to the fan sucking and blowing the gas onto the burner

Hello, you are giving very good technical information. I wish you would add the description feature with Turkish subtitles, I don't know English. I write this translation as an English translation on Google and throw it away. It would be greatly appreciated if you add the Turkish subtitle option to your videos

Hello, my boiler has the following problem: When I request domestic hot water, the boiler works correctly, when I turn on the radiators the boiler starts with the burner at minimum power after a few minutes the burner starts to regulate, sometimes it stays at minimum power and then goes out. Please, can you give me some suggestions? Thank you

Hello, can I send photos of a valve? I don't understand how to connect my differential pressure gauge to check the gas pressure. Thanks

Cheers lads

Great stuff as usual. I've got a question if anyone knows and it's regarding the very first valve you worked on. I was working on saunier Duvall Xeon. Pilot would light but main burner wouldn't. Question 1 How does the ignition lead send the signal to the pcb that ignition is present? Is this similar to flame rec? Question 2 MI's indicated this was a board fault, but customer already had another guy fit a new board so discounted this. I checked connections on the lead and the lead itself but still no joy. Anyone any clues as to what was wrong. I called glowworm but they advised that they can't give any technical help on this product anymore. Cant help but feel I missed something simple.

Good afternoon, Questions: 1) Why does the gas valve have two coils (V1 - V2)? 2) Why do the two coils have different resistance measurements? 3) Do V1 and V2 open and close at the same time? Thanks

Wonderful

Thanks, great video. :-)

Hope Roy wear a microphone next time thanks for sharing Allen.

Mila esker. Thanks

sir .how r u ? i liked your videos as the videos are informative to me. sir , i m trying my best to get admission in you academy in uk and i want to be an gas engineer . whats is to do for me to be trained by u ? please tell me.

Fabulous 👍👍👍

which helps big safety to all

🤩🤩🤩

It was a formative lesson but it would have better if it was zoomed in so I could see the gas valves better.

Good evening, do the two solenoids V1 and V2 have the same function? Why is the resistance measurement of the two solenoids V1 and V2 different? Thank you.

10:50 Good

👍🤓👍

Yes, more tech stuff that manufacturers don't give you

can you help how to advertise a business

Me names Allen Hart.....

Make

Roy's a great trainer, seems to have a great way of delivering a great lesson 👍Thanks for sharing allen.

Great video
