The best teacher so far well done

[@CarlosArruda77]

At minute 23:30, when you turn the oven to simmer, why do you have to wait for the flame to go down (thermal electric device) and with the door closed? Is it not the control knob that controlls the flow of gas to that oven? I only do meters and have done so for over 6 years now. It's good to know how all these things work. There's too many people/engineers saying that the control knobs are too safety devices which they are not! Great video.

[@richardpurvis5272]

Excellent video, very informative and easy to understand. Cheers

[@antonybuckley2645]

Great videos, great lecturer wish all gas lecturers were like this

[@antonybuckley2645]

Tom one subject that would be good to cover is kitchens with conservatory built on back, not many fully understand the requirements and the difference between purge air and combustion air

[@Matteo-rs7nk]

Hi Derek .just want to ask you instead of blowing the flame 🔥 out and let gas escapes , can you test like turn the tap off and listen for the click”shut “ ??? Is it correct doing also this way ? Or should blow out always the flame ? Thanks

[@tomkatgastraining]

If you turn the tap off you are not testing the safety device even though some training manuals say you can. When I blow out the flame I simulate real life scenarios and you test the safety device is shutting of the gas if activated unlike turning of the gas tap and listening for the thermoelectric closing isn’t telling you it’s working and turning the gas off.

[@frankdunham6051]

Another great tutorial Derek. Can you tell me how we define low and high rate (15:45 in this video) I have looked through my notes and can't seem to find reference to this part. Kind regards

[@tomkatgastraining]

When a liquid vapour valve lights it has a low flame from the bypass but when the liquid vapour valve opens it goes to full rate you can see from the video the flame is low and then after a few seconds it’s goes to full rate

[@frankdunham6051]

@@tomkatgastraining I get it - thanks, super quick reply :)

[@andypandyv]

Hiya, can you just clarify something please. 4:50ish, you say that the lid safety is ONLY to protect the glass, but then why is it ID with it being inoperable if the glass lid is broken/missing? I could understand if it were due to it also preventing the escape of gas but not solely based on protecting the lid

[@tomkatgastraining]

It’s only ID if someone has made it inoperable ie Someone has jammed some wood in to keep it working

[@charlesotto-olak1367]

Derek must be one of the best trainers in the Industry he makes the process so plain to understand, i wish i had known about him before i did my training, anyway i have a question regarding installation of flueless appliances in multi occupancy buildings, the question is what does is the meaning of multi occupancy? a. is it a building with many occupants (whether low rise r high rise and terraced dwellings)? b. applies to residential flats within a lock? c. a&b?

[@tomkatgastraining]

Any place where people live from different families can be classed as multi occupants most commonly they are flats or student accommodations.

[@integral32gb]

Hello Derek, excellent video as a lay person I understood everything. I could you help with a problem with my Cannon Stratford 10530G. Everything works as it should apart from one thing When turning on the oven, either with the door open or not, the flame takes many minutes (sometimes as long as 5 mins) to go from low rate to high burner. Once it achieves high burner it behaves as normal and responds to the knob control and sets the gas mark correctly. It has a liquid vapour valve. Any ideas whats going on there?

[@daverich3352]

I like the video, very clear descriptions. The reason I was watching is that my oven recently developed a fault, when I try to used the oven the flame is never larger than the small flame seen during ignition, regardless of the Gas mark setting on the dial. Is there a way to verify if this problem caused by a faulty thermostat or the FSD?.

[@vussprungteknik3337]

Or under sized gas

[@lostinthoughtscalminsilenc8167]

@@tomkatgastraining thank you. I’ve asked about a hundred questions recently as my acs is next week

[@Randomguy-b5r]

Tomkat, I have a question, I have a gas cooker where you push the knobs in and turn them to let gas through, on one of the knobs I have noticed that turning it without pushing it in allows gas to flow to the ring and light, whether pushed or not, is this a potentially dangerous fault? The other rings work as intended, minus one that won't light

[@tomkatgastraining]

If you have one that doesn’t light then maybe it’s time for a new one or get a gas engineer out to check it’s safe 👍🏻

[@Randomguy-b5r]

@@tomkatgastraining And the weird issue where you no longer need to push it in to get the gas flowing? The one that doesn't light is because a silly woman clogged it up with bicarb powder to clean it

[@lostinthoughtscalminsilenc8167]

So if no ffd the gas still comes out? Just confused as if the thermocouple isn’t heated wouldn’t the valve shut anyway?

[@tomkatgastraining]

It’s not a thermocouple in a liquid vapour it has a Phil 2 completely different things. Thermocouple makes a current while Phil expands

[@hafizimran6021]

At around 21 minutes you tested the thermo electric fsd and when you lit the oven burner it didnt have a bypass low burner flame. Can you just advise why this appliance doesnt have a bypass on the valves? Thanks.

[@tomkatgastraining]

If it has liquid vapour it has a bypass but if it has thermocouple it doesn’t have a bypass rate

[@michaelhibbert2907]

@@tomkatgastraining I re watched the clip and noticed when I went back to my handbook Thanks for replying these videos are gold.

Hi Derek where is the bypass in the thermostat, if it goes out on reaching temp is the bypass easy to access. Also have you done any videos on stripping and replacing parts in a cooker

[@haydernagey5881]

[@mj0n4id36]

I watched this again because it’s fantastic and this guy is a legend. Question time 😊 If the oven is liquid expansion and you blow out the flame it goes off but if you press the ignite button it would turn the gas on at the bypass rate? However, if the oven is thermo electric and you blow out the flame and then press the ignite button it would remain off?? That’s how I understood it. Is this correct? Thanks Derek. 👍🏻 Asian Jon. Training.

[@tomkatgastraining]

Correct mate 👍🏻

[@gtroadster8035]

Hi pal.. in regards to the LEV. I seen that you put it down on simmer to test the Theromostat. But how will the burner stay on high flame if it’s on simmer mode. Doesn’t simmer take it to the bypass rate? I’m Just abit confused there..

[@tomkatgastraining]

You use simmer or slow cook to make the test quicker. You would be waiting ages if you left it on max and the waited for the flame to go down. If you watch it again it will make more sense 👍🏻

1- is it dangerous if we forget to turn off the gas from bypass (Liquid Expansion ) , or if the gas keeps going for a long time and we lights it then... I like the way you you test the thermocouple,is it enough or is it still necessary to test the thermocouple on: a) Running at op temp b) Turn of gas either by service valve or ECV c) Start stop watch - listen for valve to close d) Tightness / let by test either at pressure test point on appliance or the meter 2- How can we identify if a FSD is thermocouple or Liquid Expansion Your answer will be much appreciated
