Fitting built in gas oven ...

Jethro pretended :

These things usually just plug into a wall mounted gas outlet socket.

Jethro has brought this to us :

They all (so far as I am aware) use a flexible feed pipe fitted with a quick disconnect bayonet at the end.

A Plumber explained :

Why? Our present gas hob (electric oven) uses a flexi pipe and our free standing oven (2 ovens ago) had a flexi to feed it. It makes them so much easier to install and when needed, to service.

though, but that was fitted with a ridgid pipe - so at least we'd need the socket fitted ...

of course if it does come with a standard pipey-thingy, then the socket could be fitted whenever ....

Certainly gas hobs now have to be on rigid pipework but AFAIK ovens are still OK with a bayonet jobbie?

FWIW, when our present gas hob was fitted, I recall the fitter saying it had been incorrectly fitted (previous owner) as they had used a flexi pipe, and it should have been rigid. He left it according to regulations (so the wife tells me) ...

WHICH MEANS ... there conceivably could be the socket left behind, in which case I can fit it myself :-) :-)

I shall unscrew the old oven (below the hob) and investigate.

I think the manufacturers instructions can override the ridged piping requirement on hobs. However they usually are hard piped. Ovens are more often on a bayonet since it makes for easier installation.

But as with most things, these regs aren't retrospective; if Harry's hob was installed according to the rules prevailing at the time, then he certainly has no need to rip it out and have rigid pipework fitted...

Not to current regs, but could have been correct at the time of installation. No necessity to update so I'm not changing mine.

That does not appear to be the case...
