Gas hob fitting regulations

DavyD_83

Hi All,
Sorry if it has been discussed before, I did search and couldn't find answers.

I recently got an entire new kitchen fitted and the plumber then hooked up my gas hob. When kitchen fitter was back to do a couple of fixes he commented that my gas for hob seemed pretty shoddy.

So, trying to figure out if job is up to standards but slightly below amazing, or actually doesn't comply.
If it doesn't comply I assume I can call plumber/heating guy back and ask to fix. If not, looking for advice on getting fixed.

The 3 things the kitchen guy noted:

• No local on/off valve or tap under hob
  -> Not sure if this is a problem, as there is a bayonet fitting which I think covers regulations?
• Pipe from hob to bayonette fitting is rubber pipe hanging lose (not fixed to wall)
  -> This kind of annoys me because plumber had made a fuss about how all gas pipes had to be firmly fixed to a wall etc. I turned my back, forgot to check on finished product, and this was result.
  Big problem?
• My top drawer under hob does not close fully anymore, because gas fitting is in the way.
  -> When I questioned it at the time, plumber said that I would probably need to take a lilttle chunk out of back of drawer to allow space for gas pipe. Kitchen fitter said he couldn't do that because he wouldn't be responsible for a cut edge knocking off a gas pipe and possibly cutting through it over time. He also thought that it would be no issue at all for plumber to simply turn the hob fitting up slightly to take it out of way of drawer.

So, who's right????

I'll try get take some pictures of the specifics and get em up over weekend in case that's not v clear.


[TL/DR]
Should there be a local on/off tap for a gas hob?
Should all gas piping be secured to a wall or is a flexi-pipe behind units ok?
Can connector to a gas hob be adjusted to provide clearance for drawer? (prob needs pictures to answer)

First off, a bayonet fitting does meet regulations but it is best practice to install an isolation valve before the bayonet, however, a bayonet fitting with flexible hose is only installed on moveable cookers and not on a fixed hob! It does not make sense to use this fitting.

Second one, as above. Odd use of fitting and flexible pipe. It would normally be done in rigid copper with an isolation valve.

Third one, I would imagine that if he used rigid copper and brass fitting to hob, this would not have been an issue. I have never had to "hack" a unit to install a hob! The only issues that I have come across is where granite work tops are fitted on ply and the finish flush with each other and the hob clamps are not long enough to reach under the ply. So in answer to your question, yes of course it can be fitted correctly with no hacking of your units required.

I would rather spend a bit longer and take some pride in my work and pipe fitting skills than use a rubber hose on a hob.

I don't know if it's just me but I was always thought to use bayonet's for cookers and ovens and ridget for hobs.

What's the point in having a drawer if you cant close it. Did you get a number 3 cert off him too?

Agreed guys, but some hob manufacturers instruction do say, connect via a flexible hose! (not my choice)
IMHO should be rigid pipework, always a better job.
