Non-standard gas hob

Qualitymark · 10-10-2013 5:13pm #1

The plumbers discovered that our gas hob had a tiny leak; not dangerous, they said, except that it also blows out very easily. Apparently more modern ones (this is c1990) have a cut-off that turns them off or relights them or something if they blow out.
I went to Ikea and got a hob the correct size and brought it home. Unfortunately, its connection was on the right, whereas the old one's wasn't. And it seems that all hobs - or virtually all - are now standardised to have the connection on the right.
The plumbers said it was impossible to connect the new one without removing the whole worktop, which is more expensive than I can currently afford.
Would anyone know where it's possible to buy hobs that connect to the gas supply on the left or in the centre?

Why would the work top need to be removed , I've never come across such an issue before

If the plumber can connect a hob on the left surely he can connect an extension here to run a new pipe across to the right? He may need to drill a hole in the side of a press or other obstacle.
Cannot understand why he would need to remove worktop. A photo would help.
I assume plumber is a RGI.

He obviously has access so i don't see his problem. A plumber i would have confidence in.

Thanks, lads. Pictures (can't remember how to glue in pics so they show, so they'll just be jpeg links) of current hob, and current hob connection.
To the right of this as you look at it is a dishwasher, with no clearance above it. Moving the hob to the left would mean putting in a new worktop.

Sooo… anyone know of a standard size gas hob with a connector on the left or in the centre?

phester28 · 11-10-2013 2:23pm

it looks to me ( a non plumber) that the hob is put in 180 degrees rotated. would not any side control be able to do this same rotation?

Alot before came like that. Its right way round.

One solution I had to a awkward hob was use a gas flex with the bullnose connection that you use for bigger hobs that need to be moved.

Drill the side of the press. Lower the hob with flex attached. Fish it through the hole as you drop. Connect to the wall mount and your away.

Qualitymark · 11-10-2013 4:02pm

I think putting a new hob in there 180 degrees rotated would put the control knobs at the back wall, unfortunately, which isn't feasible.
The trouble with any idea of drilling a hole and feeding it through is that the dishwasher fills the whole depth, length and width of the space on the right; unless I could drill a couple of holes through that (squirty!) it's not a solution!
The only solution to get a gas hob is to find one that has the fitting on the left.

Either way you will need access to th rh side unit as the hob will need to be secured properly via work top clamps. You will need access to these on boh sides and therefore will need access to the rh side where the gas connection can be made.

Er, why? The old hob (see pic above) sits in quite happily with its connection in the middle!

shane0007 · 11-10-2013 11:22pm

Loose unsecured hobs can lead to movement of the gas pipe & connections which can lead to gas leaks. That is why they are supplied with clamps.

Qualitymark · 11-10-2013 11:25pm

It's been sitting there with no movement for 25 years, so far. I reckon it's clamped in.

Then you probably need access to unscrew it

Qualitymark · 12-10-2013 7:03am

Access is no problem. The problem is that there isn't clearance for the pipe on the right.

Er!! because the Manufacturers instructions request it and the RGI must fit it in accordance with MI.

Some appliances can be turned by 180o, i suggest you contact one of the larger appliance stores and see if they can give you a specific model.

Thanks for the link; unfortunately, these don't mention which side the connection is on. This seems impossible. I think we're going to use the current hob until it becomes unusable, then switch to electric, with maybe a gas camping hob for the occasional stir-fry.

If one manufacturer makes them others will, if you contact a supplier like the one Billy mentioned you would be more likely to find what your looking for.

To install with right hand connection, little bit of work but no problem!
You'll have to take dishwasher out.
Prefit a bayonet hose to hob, mock fit hob and mark out a track for the hose to sit into back wall, get the kango and remove the track as deep as needed and as long as needed to get the hose into the next press with the bayonet hose recessed into the wall you should be good to go.

Please be aware only your rgi can work on the gas equipment!

that is lateral thinking. Well done!

esox28 · 12-10-2013 7:38pm

No you'd have to run it horizontaly ;-)

Robbie.G · 12-10-2013 8:09pm

I always thought that hobs had to be piped solidly not flexible hoses

esox28 · 12-10-2013 8:35pm

they have to be piped using a bayonet type flexible hose suitable for intended gas type, connected to an isolation valve to the right (usually) press beneath the hob.

corkgsxr · 12-10-2013 9:36pm

My thoughts were on a full oven/hob unit it had to be bayonet and flex. As they can be moved easy.

Counter top hobs could be solid pipe or bayonet.

Yes your right robbie but flexible hoses can be used if there isn't an oven underneath the hob. I think there's even heat resistant hoses but I'm not sure
