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.

DP is right

am not going to comment re the rubber hose as we have done that to death

Copper is the pro way.

good luck mate hope it all goes well with you and your shiney new badge

to connect a gas hob rigid pipe is the only way to do it,have never used a hose for a hob and never will

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

Yes unless instructed otherwise by manufacturer's instructions.

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.

So can I assume the rubber tube off me u guage and a couple of jubilee clips is not right? Check for leaks with me lighter and if nothing ignites, i do a cut rate deal of 300 quid!

I hope corgi have been notified of a gas appliance install in all seriousness.

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.
