Why would anyone dare give “gas" advice to anyone non licensed?
I have written several articles regarding the dangers of non qualified people dabbling in gas installations some were even posted in Australia in 1999
The problem is complex as we size gas piping by developed length, BTU IN PUT of the appliances and of course the specific gravity of the fuel we are using not only the type of fuel.
I use copper Type L for example for medical gas installations and all joints are brazed with an alloy that requires a melting point greater then 1.200 Deg F
On natural gas I use black threaded steel up to 3 PSI
The idea of telling someone how to work with gas piping is highly dangerous at best as how does one convey the idea of free air for combustion and where the vents should be located and how to properly test for spillage?
Not all materials are computable with all types of fuels and what about pressure considerations and is this installation in a high climate area of sea level? How does one explain about properly sizing the orifice?
I read the postings about one agency in England saying they inspect boilers etc in other countries I wonder how can they actually enforce their code or issue fines in foreign places?
In America we switched from the American gas association to Canadian standards and still use the National fire Protection Association 54 plus local city codes.
I was on a job several years ago installing caulked cast iron roof drains and saw gas piping installed by the building maintenance staff and contacted the building engineer letting him know there were several code violations and he said impossible as we copied all the piping from the inside installations
I brought to his attention the "drip legs" were installed outside where freezing temperature could freeze any moisture laying in the cap and thus cause a gas leak by the return air of the AC units
I also pointed out black steel has to be either wrapped or the very least painted as it is exposed to the elements snow, rain etc.
A little bit of knowledge especially with fuel /gas is highly dangerous.
One of the questions I used to ask when giving courses was "how much oil does one use on Oxygen gauges to prevent rust"
If the students said even one drop I would have then take a course in gas fitting and welding.
The students were supposed to be mechanics but like many people today they think they are above getting certified officially and here lies the major problems with giving gas advice out
