Oven and hob connections

[sharpspark]

How should gas pipes for built in oven and hob be terminated ready for the oven and hob to be fitted? Do you use a bayonet socket for the oven? Conventional or microbore? Threaded fitting for the hob?

No hoses, all must be fixed copper pipe. Pain of a job. You have to put pipes on the oven and push it backwards with things arranged so you can get to the pipework afterwards to connect up. I usually use 10mm pipe as it's easier to shove about and bend tightly.

Best you can have left ready is a fixed pipe with a gas cock , capped off.

Thanks - exactly what I needed.

On the access front, we're putting a built-in double oven under the hob - will this mean that we have to allow access from the cupboard to the side of the oven to connect up? If this is the case then I could site the gas cock somewhere more convenient like behind the cupboard rather than behind the oven? Would you normally connect up the hob then push in the oven and fiddle around connecting that up?

Sounds typical. With a single oven you often get a few inches under the hob but not with a double so there's not much choice. You have to use the correct fixings for the hob - not just silicone - which means it has to go in first. With a bit of pipe poking off to the right (usually) which ends up behind the adjacent drawer or cupd. The small bore copper is quite bendy, which makes the job possible!
You can't feed a pipe sideways from the oven as easily as from the hob so you need some access from the side at the back. Longer lengths of copper with slow bends are easiest to pull across.
Make sure the pre-fitted bits are tight - they often end up leaking. Your corgi would check for leaks before touching the system then afterwards.

Brilliant - thanks - and particularly about leaks in pre fitted bits!
