Perfect gas

Thank you so much! This was exactly the info that I needed!

Appliances should burn without soot or yellowing, a nice blue flame without yellowing or soot is clean and perfect.

Everything is wonderful and great not allowing for the fact that having different pressures for butane and propane actually equalised their heat output. I mean it's not like we haven't introduced less strict regulation on standards to harmonise before?

Wonderful video except yes make sure the gas is off before undoing it :)

An unqualified amateur? I didn't realise that there is a qualification in being an amateur. 🤔
