In my new kitchen design, unusually, the Gas hob is to be sited above the dishwasher. I would get a corgi registered person to fit it, and all the regulations I can see regarding distances to flamable surfaces etc are all fine, but I cnat see any regulations to confirm whether its OK to have the hob in the worksurface with a dishwasher situated underneath it...

I know you can have an in buit oven under it, and just a plain cupboard under it, but what about a dishwasher..???

any Corgi people or anyone else out there who have an opinion..?

guess my concern would be that it would wobble when the dishwasher was in use...

thanks

My parents have a fridge under their hob. Very useful when frying eggs
!
The underside of the hob actually doesn't really get hot at all. But
the fridge is not the best, as built-in fridges tend to be poor.
Any under-hob unit should be fixed to the floor adequately with some
clearance, so
that it doesn't shake the unit. Dishwashers don't shake that much, but
I probably wouldn't
put a washing machine there.

No probs as long as you remember it's not an oven and try and roast a
chicken in it.

I see no reason why this will fall foul of the reg.... unless....

The manufacturers of either the hob and the dishwasher explicitly
state that a dishwasher/hob is not to be fitted under/over
their appliance.

The gas supply is going to be have a problem caused by the dishwasher so
that it can't be routed in a manner compliant with the
relevant standards.

The latter is a _possible_ problem mainly if there is no room for the gas
pipe under the work top and above the d/w.

Thanks - I guess I'm inventing problems, maybe i should write te regulations... what confuses me a little is that the regs, I think, say that the hob should be fitted with solid pipe rather than flexible pipe - but surely if there is ANY movement at all between the worksurface and the wall that the pipe is secured to, then wouldn'd the slight movement make it MORE dangerous to have a fixed pipe? I cant see how it is safer to have a solid soldered joint, when even if there is a washing machine further along the worksurface, then if there is small constant vibrations of the worksurface, doesnt this pose a risk that the soldered joint in the fixed pipe could fail..??

I dont get why a flexible pipe wouldnt be safer..

Flexible hoses are a lot more vulnerable than rigid copper pipe.
The worktop is of course solidly fixed to the base units or
support-battons which are in turn well fixed to the house.

Copper pipe is quite capable of flexing small amounts certainly any amount
that normal vibrations of the worktop might call for.

As I say in the FAQ there used to be a loop hole to allow suppling hobs
with hoses (there were a lot of reasons why you still couldn't). In 2004
the practice was explicitly ruled out in the regs.

In this month's "Gas Installer" magazine there is a picture of someone who
thought they could use their hob balanced on top of its packaging and the
oven packaging.

OK - so I guess I should take your word for it seeing as you're the expert - but one more point - you say;

'The worktop is of course solidly fixed to the base units or
support-battons which are in turn well fixed to the house.'

But I've got a nice new solid thick worksurface, with connections to the worksurface that have slots in for the screws to allow for the 'up to 1cm of expansion and contraction'... so that means the worksurface is not actually solidly fixed, its flexibly fixed and is allowed to move....

how does a gas pipe that is solidy fixed to a brick wall allow for a hob moving a few millimetres with the wood worksurface?

1 cm of lateral movement (not to/from the back wall) would not be
desirable but could be accomodated. This movement is not likely to be
every day more like a seasonal (dry in winter, relatively damp in summer
thing?).
