Honestly these videos are great, i'm a 20 year old trainee gas engineer and without your videos I would be so lost, its great to watch them these in your own time pausing them and being able to get better understanding, big thank you from us younger guys !
videos 1 and 2 cover all aspects of service and installation of gas fires very well. The smoke match holder is something i will use going forward. Great job!!
Great Video again part 1 and 2 you are amazing 😉 One of the best Engineers I have ever seen 150%correct you must be a bit German ✌️😎Thank you very much for sharing this Knowledge pal ☝️👍Connor
Cee Jay911do thanks for watching mate and the great comments us Germans need to stick together and show the plumbing and gas industry how to do it correctly 😜👍🏻
Excellent video, but if it fails spillage when an extractor fan is running and everything else is fine, how much ventilation do you add? 25cm2? 50cm2? 100cm2? Or disconnect the appliance?
Fantastic video. Very useful. At 13 min 17 secs you gave a recap on how to perform a spillage test. You said; Close all windows and doors, any fans turn them off, any vents that can be closed, close them, any passive stack systems you leave them open. Why leave passive stack systems open? Thanks 👍🏻 Asian Jon. Training.
might be a stupid question but how would you do a spillage test on a fire that has a glass front i.e a gas stove. unlike a radiant fire which is more open? thanks
@@tomkatgastraining i've got the instructions for a gazco marlborough and stockton stove i can see the spillage test but it shows no detail of if you need to carry out flue flow test as part of service many thanks for reply
@@tomkatgastraining As for a video suggestion: Installing a radiant type/outset wall mounted fire. Since there are currently no videos out on YT that cover the installation of those kinds of fires. For some reason I adore the radiant style of fire with the bars on them.
hello you state in this vidio to apply a smoke match / puffer / or joss stick to the edge diverter or gas fire canopy so my question is can i perform this after 60 seconds ??
where can we do flue flow test and spillage test and combustion analyse on the open flue boiler if there is not draught diverter on the flue. Can we do front of the open flue boiler? for example Glowworm fuelsaver 40r mk2. There is not any information with about this critic tests. thankk you.. Mel
Interestingly, the appliance passed the sweep test, but failed the spillage test. My thought was if the spillage test failed, sweep test would be subsequently failed as the result. Any plausible explanation on why that happened in the video where spillage test failed, but not the sweep test. Many thanks
Because the appliance was not making co the sweep test passed but because the spillage test failed then it’s ID . If the fire was in a living room not a big training room then the fire would have put out more co because there would have been a lot less oxygen in the room. Hope that helps and thanks for watching cheers
@@tomkatgastraining thanks for reply appliance combustion was nearly perfect and no CO produced due to adequate air in the room?. This led to pass of the sweep test right? where the spillage test failed, there was not adequate pull from the flue system. Combustion products will like flow back into the room where appliances operate.
@@tomkatgastraining Hi Derek pleases also enlighten on concepts of air combustion requirement and flammability range. It has been a bit confusing as they both involve fuel gas and air and relate to the ratio of fuel gas in air. E.g for natural gas, its air requirement for combustion is 1: 10 ( or 10% fuel gas in the air), and its flammability range is 5-15%. As I am aware of danger of natural gas falling with the flammability range, its air requirement for combustion confusingly is at 10%, which fall in the flammability range of 5-15%. please help on this
ilex Wang you need 10 m3 of air for complete combustion because only around 20% of air is oxygen so for every 1m3 of natural gas you need you need 2 m3 of oxygen or 10 m3 of air for the 5 to 15 % gas in air so if you have between 5 to 15 % of a room has gas in it it will explode if you have ignition. Hope that helps

Business Mind thanks for watching cheers
Great video, simple step by step explanations. I learnt more from your video than gas course in college.
Top quality stuff again, Derek. Videos greatly appreciated. 👍👍
Derek, you are THE BEST
Amazing video. Cheers Derek
Another fantastic video
Brilliant not had to do a spillage test in years ,good to refresh
Great videos Derek, massively helps as a trainee gas engineer. Watched both parts. Thanks Abdi
Great video Derek, you can watch this over and over again you gain so much knowledge from watching your videos, they are really helpful.👍👍😁😀
Brilliant video really help me today to understand the correct procedure. Cant wait to be back in center to do a sweep test on a fire. 🙂
Very well explained. Great videos part 1 and 2.
Thanks
Issa Juma glad you enjoyed it cheers
Thanks Derek..

You are really great Derek,I am studying in Glasgow and really enjoying your videos and learning from them. Thank you so much.
Thanks for watching cheers
Nicely explained. Thanks Derek 👍🏻

ACS exams next week and your videos are very helpful
Good luck with your ACS let me know how you go on

understand the correct procedure.

Why leave passive stack systems open?
Thanks 👍🏻
Asian Jon. Training.
Because the regs say if a passive stack is there test open first and the test again closed 👍🏻
might be a stupid question but how would you do a spillage test on a fire that has a glass front i.e a gas stove. unlike a radiant fire which is more open? thanks

If you don’t disconnect the fire isolation. Where else on fire could I purge?
Great video how would you carry out a flue flow test on a Gas fire stove type fire ?
I can't think answer for this any where
Matthew Whitehouse normally you would follow manufacturers instructions but most are done at the draft diverter at the back of the stove
@@tomkatgastraining i've got the instructions for a gazco marlborough and stockton stove i can see the spillage test but it shows no detail of if you need to carry out flue flow test as part of service many thanks for reply
can someone explain what is meant by passive stack ventilation
Just got me thinking are training centres exempt from GSIUR since they usually contain badly installed/ID appliances?
Ha ha ha what do you mean badly installed 😜 yes we are exempt 👍🏻
@@tomkatgastraining As for a video suggestion: Installing a radiant type/outset wall mounted fire. Since there are currently no videos out on YT that cover the installation of those kinds of fires. For some reason I adore the radiant style of fire with the bars on them.
I noticed you didn't test the actual valve body with fliud, I know that certain valves can leak from there just like certain ballafix.
hello you state in this vidio to apply a smoke match / puffer / or joss stick to the edge diverter or gas fire canopy so my question is can i perform this after 60 seconds ??
It says wait 5 minutes but if you do it after 60 seconds and it pull all the smoke up the chimney then it’s a pass in my eyes
On a DFE fire there is no builder opening so the fire does not need to be removed for Flue flow test ?
Matthew Whitehouse there is a builders opening but yes some DFE fires don’t need to be removed to carry out a flue flow test

How long flu an splich

The draught diverter is built into the boiler so it is done at the back of the boiler where the draught diverter is
@@tomkatgastraining thanks for reply, should ı do flue flow test with smoke pallet for check the flue or spillage test is enought with smoke match?
@@osmelmuhendislik807 flue flow with a smoke pellet with appliances off spillage with a match and appliance running
@@tomkatgastraining thank you very much, you are the best :) ı am your fan
Is the flue flow fails after 2nd go is that AR? And also if spiledge test fails after 3 attempts
No it’s ID
Does anyone know a website to download free gas fire manuals?
👍🏻✅
Ray Hurell
At the end it’s passed so is the fire a pass or fail
Fail because it was spilling so ID
Good video. Too much information tho. Giving it all away for those who have been in the trade for years
