What I have now is a 15mm copper pipe coming up through the kitchen floor by the edge of a wall. The pipe is secured to the wall with metal clips (screwed in to the wall) and goes up 3 feet. At the end of the pipe is the socket that I plug the hose coming out of the cooker into. It's all very secure, just exposed.
There's no shielding around the pipe and the cooker is stood right next to it however the pipe never gets hot, even when the oven is on.
Next to the cooker is a kitchen unit so the pipe is kind of behind this and the cooker so it's not in a position to recieve a knock from anything. You can just see it at the back of the gap between the unit and the cooker.
It's been like this for years and is quite safe but I am wondering whether there are any regs that demand double shielding for exposed gas pipes or require the cooker to be a certain distance from the socket etc?
