safety device testing for landlords gas safety certs.

[unitedgas]

Hi guys.

I am new to the industry. Qualified just over a year ago. I mostly work on central heating.
I've been asked to do some cp12s. Can anyone give me any advice?
Specifically on checking safety devices of appliances.

cheers.

they must all trip within 60 seconds and with your manometer on the inlet, observe no movement. The blip test. This is for the thermoelectric type on boilers and ovens. Then the bypass rate on oven stat and rectification is just cut the gas off and make sure it goes to lock out

did you not do any during your training and building a portfolio, as that was the reason for having a porfolio of works done!

thats pretty harsh we all learn on the job after 40 years of mostly instals ive gone over to servicing and ll certs and its a whole different ball game im still playing catch up after four months

 

[Linkyplumb]

Yeah bit harsh. Better he is asking than just bumbling on with it

just wonder what is the point of the portfolio, best go and buy Mr Regin's book and learn how to do some of the tests available. Ie how to check that when the gas valve has locked out, it isn't passing etc etc

No I sat down at college and listened instead of messing around and also asked my mentor how to do things, wasnt hard.

When i did my portfolio, worked alongside probably 10 service engineers and struggled to find one that new how to test controls. I now know many other gas safe engineers who havent a clue how to test controls because they have never been properly taught. Alot of stuff is just skipped over. Alot of engineers only ever install and commission new systems so never test controls apart from the usual commissioning stuff.

sad state of the industry!

 

[stratplus]

Very true

 

[Ermintrude]

Just simulate fault and check control responds

I bought an I pad, expensive if your starting out but as long as you've got a signal you can download mi's for any appliance and refer to that, always carry my orange bible (gas book) and the other one with the tables for id, ar & NSC (sorry forgot the name oops). Keep your text books in the van and a trusted experienced engineer on speed dial if you get stuck who wouldn't mind helping you out. I always phone a friend when I'm having a brain fart and likewise they phone me. Take your time, think it through, if you get stuck, make safe and seek help. It will come with time mate

You can use the blip test on gas valves with a thermocouple as flame failure, but best practice is to do a tightness test when all the appliances have gone to flee failure. Way I was taught, switch off boilers at the mains when fired up, this should cause the gas valve to close. With stuff like fires, either switch the gas off at the ecv and connect your gauge and wait for pressure to stop dropping, or the best way is to blow out the pilot and wait to hear the gas valve click as it closes. Then do a tightness test.
