How to replace a gas hob? (1 Viewer)

[colyboy]

Been a reasonable competent DIY person I would like to replace my now “caput“ three burner Dometic/Smeve gas hob in my Hymer. I have been on google for ideas of how to replace one but nothing really , most are for fitting a new one (diy VWs etc). Has any one replaced theirs? and how?. Of course after fitting I would have it checked by a safety gas person.

Are you fitting the same? if yes it should be quite straight forward as the biggest job would be if the gas was in a different place, should be held in by some little clips around the edge.

Why do you think you need to replace it as the only parts that can go wrong are the gas valves & the jets both easily replaceable.

Funfair, like for like

Screws under the black rubber bungs

It's a very simple job to remove the old one. Disconnect the electric feed, and the gas. Then undo the clips holding it to the worktop. Or in this case the screws under the black bungs

Fitting the new one. Ensure it fits the current cutout, if like for like, that is simple. Sit the new hob in place with the supplied sealing gasket and do up the clips underneath, or screws. Reconnect the electric supply and line up the gas pipe to see if it fits. If not you will need to cut the pipe back, as the old copper will be brittle. Using a straight coupler and new pipe, carefully bend the new pipe to fit. Cut it to the right length and using a new olive secure to the hob and tighten the straight coupler. Turn the gas back on and leak test using detector spray, or if not available a dash of washing up liquid and water soak around the gas joints. If you see bubbles, you have a leak

If it is an identical hob, you just need to re-make one joint on the gas and test that

It’s the Gas connection i am having probs with, of course it is under the hob , three pipes going up to it. 1 is to the fridge. 2 to the oven/grill, but which is which?

 

[denisejoe]

There should be 2 or 3 gas taps around that area which should be marked

I do not know whether what I am writing is relevant to MHs.

The gas hob in the kitchen of our house in London rented out needed replacing, agent ordered one, but when the fitter came to fit it he refused because new regulations stipulate that there must be a 700mm spacing between the hob and overhead cupboards. This was confirmed by a second fitter contacted.

To achieve this meant considerable disruption and the tenants have decided to live with it rather than have the disruption.

It does however raise the point as to whether the same regulation would apply to MHs. Would a prfessional fitter refuse to replace a hob where 700mm spacing did not exist?

And further, which country's regulations should apply to MHs - the country of manufacture, the country of sale or the country of use. Do we technically breach the law if we take our MH from a country with lax laws to use where the laws are tighter? I shall not lose much sleep whatever the answer is, but just interested.

I can't find a triangular one - you could have cut a different size hole

They are still current in quite a few Hymer models.

the connection that you are looking for is directly on the underside of the hob. Turn off all the gas at the locker before you begin

We has similar problem in our house when refitting the kitchen. The gas hob not allowed to go back in same place because it was too near a window. We had to put it on inside wall which meant couldn’t easily route an extractor fan. MH regulations must be different.

One advantage of DIY.

Technically, the regulation would apply, however if the OP fits the hob himself and connects the gas, a gas engineer should be able to test and issue a safety certificate stating it is not installed to current standards.

Having recently done similar work on our motorhome, I can confirm that it is quite simple. The only problem I came across was the old gas fitting - it was an absolute bu**er to undo without damaging the pipe. As it’s gas, you really don’t want to use heat to try to loosen the joints, and you don’t want to burr off the hex sections! I eventually managed to find spanners to fit exactly, and some suitable bits of pipe to give extra leverage, as the joints were extremely stiff. After fitting the new hob, don’t forget to check for leaks with some soapy water after changing the hob, but before screwing it down!!!
