Oil Boiler Lockout - How To Test A Photo Cell
Вставка

- Just A quick Video of how to see if a photocell is working properly on an oil boiler burner, I will be doing more videos to try and compile a collection showing how to test different components and what faults they cause
Superb video Tom it’s really very therapeutic stripping oil burners and there’s a heck of a lot more to them than most people think once you get to know all the varying makes etc.
Thanks for watching mate, have a great Christmas
You are getting very good at working one handed Tom😁 great video mate 👍
Thanks mate, Its never easy to try and film one handed, do the job and talk clearly, sometimes I stay stuff that makes sense at the time but then I watch it back and it makes no sense
@@PlumbLikeTom you're doing a great job mate. Sometimes we autopilot when working and talking to customers, afterwards you can't even remember the conversation. 😁🤭
This is very interesting, I tried this test on a failed Riello photocell from my burner and it didn't read open circuit when covered. So I bought a new one and this just read a high resistance and a slightly different resistance when covered. I plugged the new one in and it works fine. I know Riello have changed the light sensitive resistor to comply with EU Cadnium rules. Could it be that it is not just a passsive resistor as there is a little circuit board behind it. Rieallo wbsite says checking this component is very difficult and you should just replace it. But they would wouldn't they. There is a guy online who explains how to replace the photocell which is what I will try with my old one.
Good video Tom ….how did you get on with oftec I remember you saying he was being funny with you ?
I had to update my books as its on their terms of registration even though my books were fairly new anyway, I believe these cost me around £140, when you do your OFTEC reassessments you get new books anyway so I still dispute the fact you should have to buy new books on every amendment as it just seems like a money grabbing scheme, other than that I won't hear from them until the next time they want money like a lot of the registered organisation bodies. I understand the need for industry bodies but I wish we were more like the construction side where there are more for each element so they can't monopolise that particular sector. There should be private independent companies that offer the services of OFTEC, GASSAFE etc to bring costs down but these are just my opinions
Sir.. Ldo burner nozzle size 10.5 plp
Ldo line pressure 20.0 kg
1 hours which ldo consumption????
Replay.. 🙏🙏🙏
Just be careful how much information you give to the untrained. It can result in DIY boiler work and dangerous situations.
Hi mate, I was only going to do oil boilers because a few people have asked how to check different components, what I might do instead of videos is try and produce a document with different checks for different faults, This would be free to anybody who is learning or is in the oil industry, this will take me a while to make though but may be worth it and may help new engineers out in the field
But anyone can work on a oil boiler its not illegal
Thanks for this Tom.
I noticed that you had your meter on 600k.
So I guess it's still a pretty high resistance is it.
Also are they polarised? I know some of the bigger gas burner photo cells were, but thoes sent a voltage back to the control box.
our worcester burner doesn't fire on, lock out all times, have oil coming out on bleed valve, it does start but when it should fire it goes to lockout. is there a spark unit?
As a rule of thumb I always change the photo cell when I change the control box, you only get so many hours for components until you need to change them. Riello tells you in the book how many hours when you should be changing the componant.
Excellent video mate 👍👍👍 thanks
Thanks for the support mate 👍
I appreciate the comment, immediately below. That said many of us clearly from your other comments are learners/apprentices and your content is invaluable .I don't think a resistance test on a
photocell or for that matter a solenoid coil is particularly dangerous.Good point @ 0:16.If you prize the female connectors apart too much with your probes,they will be too loose when you reinstate them into the control box and can cause "arcing".I had this happen to me.Hopefully I learnt from this lesson.Keep up the good work.
Thanks mate, I am always nervous about showing to much especially on gas. I remember back to a time when I was learning and trying to pick up as much information from tradesman as possible, to me these videos that are available from content creators would have proved really helpful I don't think guys like PB, M J tiff, Allen Hart ect realise how helpful they are to younger apprentices as well as more experienced tradesman, I still pick up little bits of knowledge from them
Oil is third on my list after nvq 2&3 in plumbing then gas. But very interesting and will be a useful resource when I get to it 😊 thanks for taking the time to do this series. 👍
I really enjoy working on oil boilers, in many ways I prefer them to gas. Once you get qualified in gas its quite a straightforward transition to oil
Great vid mate 👍 short fault finding like this is very helpful. Best way I’ve found learning is to strip down old burners and just see how they go together
Thanks mate, sometimes you just got to get in there and get your hands dirty. It a excellent way of learning and once you've stripped a few down most are generally the same, just builds confidence which is a big part of the job
Loved this video tom thanks
Thanks mate, glad you enjoyed it
Great tip Tom, I’m looking at doing my oil this year so stuff like this is really helpful 👍
Thanks mate, I find oil boilers really interesting, I will try and do more videos in the coming weeks if I get time
Do you know any oil boiler specific fault finding courses by any chance?
@@84bexter Quite a few years ago I did my "introduction to Oftec" at Worcester Clay cross site. This was a one day course explaining how a burner works and how to fault find on burners. I don't know of any specific courses but it might be worth asking boiler manufactures if they provide any training on their boilers, quite often these are free
Thanks Tom, I’ve just been looking at the Worcester site and I’ve seen one on there. 👍
Good job 👌👍
Thanks Jock
