Business Mind thanks for watching cheers

Issa Juma glad you enjoyed it cheers

Thanks for watching cheers

Good luck with your ACS let me know how you go on

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 😜👍🏻

Good luck with the ACS

Because the regs say if a passive stack is there test open first and the test again closed 👍🏻

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

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

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 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

No it’s ID

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

Fail because it was spilling so ID

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.

ilex Wang yes correct

@@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

Don't forget spin dryers .
