just wondering how easy it is to change a gas hob.
thinking of buying a stainless steel hob with 5 burners, seen a couple in the sales that are dirt cheap.
i'm assuming there fixed in place under the worktop, so the oven will have to come out to access the fixings.

am i thinking along the right tracks?

thanks

You'll almost certainly have to renmove the oven, unless the previous fitter put the gas supply for the hob behind another cupboard at the side, say, as I did when I did mine.

There should be a large thick black hose connecting the hob to gas.
On the end is a bayonet fitting: twist the knurled ring, and it releases. (Could be stiff: pliars, mole grip, water pump pliers etc. Twists anti-clock).
To refit, push into place hard, then twist in opposite direction.

With my old hob, you could fit it from above, but the new one needed you to take the drawers out beneath as it fits from below.
The good thing is that the new ones fit into the cut-out for the old, smaller ones, but may end up off-set slightly.

BTW: removal of single oven, also easy look for fixing screws down outer edge inside drop down door, then pull forwards.
Beware: heavy!!

And if you buy stainless, welcome to the cleaning cycle. Sigh:(:

Not all gas connections have bayonet fitting.It may be a old one where the hose is permenatly fixed .to change this you need to switch the gas off,and replace the fitting so the new bayonet fitting can be used.

This should not be done by a DIY person!!

Also check that your new oven comes with the hose attached onto the back of it.If not you will need to contact your local Corgi reg'd man,to connect it properly onto the appliance using the appropriate methods:)

Tut Tut alcazar it is illegal to have a flexible gas connection to a hob, it must be plumbed in rigid pipework with a isolation tap. Please try not to give DIY advice on gas work, only a corgi reg engineer with the relevent qualifications is allowed to do this.

Mog - is it okay for a non-Corgi bod (DIYer) to disconnect such a hob? I want to do the very same next week. There's an isolation tap there, and the rigid pipework as you've detailed.
I'll be getting someone in to connect and commission the new hob, I was just wondering about taking out the old one.

Ta.

It's illegal to have a flexible connection?

Why?

Alcazar

Mungo..you can't disconnect the hob even if there is a isolation valve because you are not deemed to be competant to test if the valve is letting by and the valve needs to be capped off...all this can only be done by a corgi reg engineer.

Alcazar..the reason you can't have a flexible bayonet fitting to the hob is the heat build up from the oven in the cupboard below, the hose can get pinched by the oven, trapped against a hot surface etc.

Mog

OK, I can go with that, but is it the same if there isn't an oven? My oven is electric, and in a unit opposite?

It is a rule that applies to all gas hobs regardless of cupboard configuration.

Mog

Well how silly.:(:

And my hob had/has a fitting on the bottom into which the flexible bayonet tube other end screws perfectly!:(:

Alcazar

Mog is right - It is illegal to tamper with the gas connection to a Hob it can ONLY be done by a Corgi registered engineer. I got into this mess a few months back. A corgi registered engineer should fit for about £50
