looking for input on the subject of LPG and/or NG valves ........ somewhere in my distant past I once actually was registered to fit domestic gas ....... but that was over 10 years ago ....... and i have a faint memory that may or may not be my imagination and failing memory of old age (well middle age really) ....... something about gas supply valves not pointing downards towards an appliance ... something to do with CO rising perhaps? ..... anyone shed some light on to this?
thanks
Simon
Are you perhaps thinking of lever valves which should be oriented so that the weight of a closed valve lever cannot influence the valve to open again by gravity? You could regard a lever which is down to open rather than up to open as contravening this requirement, certainly the ubiquitous gas service valve adjacent to the meter (AKA known as emergency valve and various other titles - it changes its name every now and again according to the whims of whoever is writing regs at the time) should have the lever vertically upwards when "on" and horizontal when "off"
nope ..... I'm sure it was something about gas taps for isolating appliances not being fitted pointing down
thanks for the reply

Perhaps this stems from the need to install bayonet socket connections pointing down (to prevent ingress of dirt).
