Some one i know had a boiler fixed over christmas by a gas engineer.And to cut a long story short about wanting a new gas hob and electric oven not going back far enough, the gas man said you are allowed to fit a flexy onto gas hob to get the pipe back to wall far enough for oven to fit.
Now being in the process of completing my gas exams im sure you are not allowed to do this and it has to be rigid copper pipework to hob with a gas tap on, im i right or misunderstood ?

again under the BS for pipework and for cookers and the GSIUR there is no reason why you cant fit a proper cooker hose to a hob, as long as its not subject to heat greater than 70 degrees...

MI will tell you if the back of the oven will be higher than that.

I personaly would fit it in rigid , how much easier is it to fit a hose to a built in oven too...

and as for a valve... if a boyonet or micropoint is perfect but the regs states a valve should be fitted to all appliances where practical... does behind an oven

1... become practical and
2... become a compression fitting that you cant get access to ?

You are not correct as per BS6172. "unless stated otherwise in MI's, a gas hob shall de connected by a rigid, fixed connection."

you are right in what you are saying but getting ity back to front if that makes sense, the BS says you can fit with rigid or hose, UNLESS the MI demands rigid,

I know, I thought Id seen it in BS, Viper or corgi book the other night. Rememer thinking it strange why someone would use Tracpipe under fixed hob. Got a feeling it might have been on an indesit hib MIs though.

Apologies gbgas001. I have a hard copy of BS6172 that states the above quote. It appears to have been abbreviated. Going in bin now. I looked at my PDF copy which states the info bellow in full

!11.1.3 A gas hob shall be connected to the termination point by means of rigid pipework or, unless stated
otherwise in the manufacturer’s instructions, a flexible connector and self-sealing plug device conforming
to BS 669-1."

Cheers kirky!

think i,ll just stick to what i no,and have been taught and thats rigid with gas iso,when on gas course we were also told if cooker is gas and not going to be moved that has to be rigid aswell

so i asked how do you get to it and answer was, connect it by were kick boards are

Personally, Ive always fitted hobs with rigid copper. A cooker hose IMO is, as already stated, a lazy way to connect a hob up.

i'm not having a dig at you by any means, but some of the things you were taught sound dodgy to me, the statement about cookers not being moved so need to be hard piped is made up, (as i said by your trainer not you)

i realy miss the days when all cookers were rigid conections usually 4 niples 3sockets and a longscrew connector

by flexi do you mean a braided "plumbing" flexi? if so you are all correct, if by flexi you mean a bayonet fitting and hose, they are allowed unless the manufacturer expressely says must be fitted with rigid pipework, however a bayonet hose has a heat limit of about 70 degrees C so if it is behind an electric oven care needs to be taken to ensure the position of the hose isnt subjected to heat above this, however because im saying it is ok in some situations thats not to say i agree, it is laziness of the highest order, and a properly fitted copper supply means the oven fits in no problem, i used to do loads of kitchens as homers and we used to go on a friday night and strip everything out, on checking the MI for the hob and if it was allowed i would rig up the new hob onto a frame and use the cooker hose and bayonet to connect it to leave them the use of the hob overnight, temp work like that i was happy with but never agree it is a finished job,

If you are allowed to use a bayonette fitting and hose under Mi's Then it has to be run in a U shape drop and not touch the floor or pass through any kitchen furniture. Far easier to ridigid fix. About time the regs stated ridged fix only.

Agree entirely with kirkgas, there becomes common sense when oven fitted underneath.

perfectly acceptable to connect hob with flexi as long as confrms to mi and doesnt come into contact with excessive heat from oven below and complies with regs regard use of flexible hoses.......ps have allways found kirkgas spot on with his advice

Well guys thanks for all the interesting replies, seems i started a debatable thread here. Well as it goes my gas engineer has got the job of fitting a new hob at the guys house so i will be fitting it with him tommorrow, it will be interesting to see m.i.s of new hob.
Im presuming the other gsr was refering to rubber hose and Bayonnet fitting.
