Great video Roy and Allen.I’ve had a few venturis blocked with bumblebees🐝 Great tip with the brass t pieces👍 Keep up the good work

[@davidb2464]

Hello again Allen, Roy did answer that question for me, as opposed to low pressure, it's actually the negative terminal, so all good. Nice vid Roy.

[@colin5064]

Great video once again most helpful and clearly presented

[@smellslikethinice1107]

Thank you guys, Allen and Roy...great stuff !

[@simonmander4314]

Brilliant video thanks Roy and Allen. Any chance you could do a short video on how to oil/free a seized fan to temporarily get it going?

[@sunvird4434]

i find spraying wd40 on the metal propellers, seems to get in going.

Hi Roy + Allen -- love your fault finding videos -- i've been a gas engineer for 47 years and i'm still learning , theres always something new to learn -- i've been to Vaillant + Vokeras trining centres a few times which are both close to Haifax , your training centre at Viva in Halifax looks a great place to learn about gas appliances -- the local trainees are very lucky in your area --

[@michaelrose7258]

Thanks guys. Awesome as ever

The I've never really used the pressure differential on digital manometers. Great tutorial team Allen ♥️. I'll be sure to try this when I'm next testing an aps or fan venturi. The ferrolli modena 80e had those troublesome venturi's which always seemed to go brittle. You guys have a fountain of knowledge between you. I take it you're both ex British gas engineers?

[@nasa7886]

Hiya... Really great video. How do you know where to put each wire on the three terminals if mixed up and didn't take photo?

[@paulsmith2931]

Another useful and well explained video👍🏻

[@paulsmith2931]

Great video, putting the tubes on the wrong way round on the fan, you would still measure the differential pressure on your manometer the same.

Viessmann 100-W 35kw, 2021 version Vs Baxi 836? What would you pick?

[@user-zm1nt4tq3v]

Thank you so much for this experience

Hi what pressure would you be looking for across the hoses?

[@veronicahart450]

Really good video

[@simonmander4314]

Interesting to see the Worcester Ri has an APS fitted to the flue way inside the boiler.

[@bootneckbonz]

Great video. Can you test the air pressure switch using an old school u gauge, or does it need to be digital? Thanks, and great instruction as always 👍

[@Big_Old_Bondy]

Yes you can, a u-gauge will work exactly the same

[@bootneckbonz]

@@Big_Old_Bondy cheers pal 👍

[@IsmailBhayat-lf4od]

Super explosion 👌

[@sesquepedalian3968]

Are there air pressure switches on every boiler?

[@jasongeorge4602]

Its ok to check for continuity on the aps even with power on ??

[@royfugler9971]

Hi Jason, No the leads need to be removed from the APS to check for continuity

[@davidb2464]

Hi Allen, when Roy mentions fitting one hose to the high pressure side and the low pressure to another, is this simply the + and - terminals on my Anton, as the Anton he has seems to be a stand alone manometer? BTW, please could you stop loving every message, as it denigrates actual real good ones that you do actually love for its' content IMHO.

[@royfugler9971]

Hi David, Thanks for the feedback. If you using an Anton FGA connect the high pressure to the +ve & low pressure to the -ve, if you did get the the wrong way round you would end up with the same reading only it would be a -ve reading.

[@davidb2464]

@@royfugler9971 Hello Roy, thanks for the excellent pointer and the clear explanation.

[@Carl-re6zb]

Thank you guys.👍🏾

[@leaturk11]

top job

[@k956upg]

I just blow an egg cup of water through the tube into the Venturi to wash it.. Listen for the click of the switch…suck on the switch tube to see if it fires up.. Check open & closure etc with a meter to prove micro switch…im not buying a pressure tester as ap switches are becoming rare now…not sure why this video popped up but literally first job today is a main 24 with a flashing light during ignition…spooky.

[@mrh2602]

Really need to explain that continuity should always be checked with no power to the item being tested.
