Hi all, im new to these forums, Im just out my apprenticip as a domestic gas engeneer. CORGI registered (you wouldnt think i was wi these questins lol) I usualy work on CH Systems, repair and service mostly.

But ive never had to work on or install a gas hob before, apart from the cooker in the ACS

Was just checking, the gas hob should be connected by ridgid pipe and not a flexi cooker hose is that right ?

cheers folks

Hope I can start helping folk wi there CH questions and get some knowlege off the guys that have been in the industry a while.

This topic has made waves. Very big ones. Topic had been hammered to death.

I would plumb it in 15mm copper and install a stop valve. Would never use a hose (even if maker's instructioned allowed it).

Matter of pride.

Go for copper - even if hob manufacturer allows it - hose manufacturer almost certainly won't ie ambient temperature too high, contact with oven, unable to hang as a U

I don't use 15mm any more, microbore is so much quicker, and a damn site easier if the oven undeneath is tight at the top back.
The drop on a short piece of even 8mm is insignificant. 10mm will go a long way. Compression fitting-reducers are very handy, use the gas cock and one of then to get down from iron or 15 or whatever.
You do need to stock a few fittings for the ends, some hobs needing 3/8" iron connectors etc.

HObs are hard to install properly! Their gas supply is usually teed off the feed to an old boiler so they don't get 20mbar when the boiler's on. It's often way down, so the job's half an hour for the hob and half a day for a new gas line.
But if you ( I mean, I) do a Landlords gas check on a hob installed on 16mbar, it's just " Not to current Standard" which is good enough. Barmy.
