Gas Hob installation

[merv]

Hi all, I installed a gas hob today (New world 60T). The manufacturers instructions said for it to be fitted with a flexi hose. I've never heard of this as always understood for gas hobs to be fitted with a rigid pipe. How odd!!!

 

[gasmarc]

I would say no to that myself if being installed over and electric oven also does the hob have a ffsd fitted ?

I would agree and connect it with copper, but of course if the MI's say different!!!!

 

[merv]

Yes, ffsd fitted. I,ve told the homeowners to keep the manufacturers guide incase an engineer queries it in future. But it's in black & white.

 

[kirkgas]

does the MI spcecifically say "connection MUST be made by flexi hose" or "connection CAN be made by flexi hose"

 

[aqualogic7]

if an EU product you are aloud to use a flexi hose in some eu states ie france

Connect gas hob to gas supply
The inlet is at the rear RHS of the hob. The hob may be connected to the gas supply either by rigid pipework or flex- ible connection.
Flexible connections
Use a 900mm - 1125mm length of flexible connector. Ensure that the hose is installed hanging freely down- wards, is not trapped, is not subjected to undue forces and is not supported at the bottom by a horizontal surface.
Natural Gas - Flexible connections should comply with BS669, latest edi- tion.

I've just spoke to Gas Safe. They said if thats what manufacturers say then either way is ok.

its fine aslong as the hose is not subject to high temps (above 70 degress if memory serves me) ie behind an oven or subject to stress/chance of stress.

surely abit of copper pipe and a few fittings is cheaper anyways?

this reminds me of my mate who went to wicks to buy some power tools, Up shot of the story my mates was at the till with 3 different power tools and the cashier asks the manager the price twice and the manager replies £11.99 twice and the cashier says to my mate well if the manager says its that price for 3 it has to be lol. My mate could not believe his luck

why do you need to confirm specific MI's with GSR? and surely this was covered in your ACS?

ad say heat from the oven is undue forces,theres no way id fit a flexi and were its hidden 99% of the time and you carnt check it and you might find that if the mi,s go missing or you carnt get hold of them in the future if its foreign and someone might riddor it

 

[Pssst]

If it was a matter of choice,I'd rigid fix.

i always comment on the threads about hobs and flexis usually because people confuse their opinion with the law, IF the MI say you can connect using a flexi and you do so, properly and complying with all regs and a couple of years later someone RIDOR's you they will be left to look like an incompetant idiot when you get pulled and cross ref the MI and prove you are right, as long as you are right in the first place its of no interest what idiot follows you, let them suffer for not knowing how to do their job, if i was following you and seen the flexi and didnt have Mi's i write on my paperwork "hob connected by flexi, no MI, confirmation required tha this is acceptable" this then passes responsibility back to someone else to check it out, same as free standing cookers re clearences, no MI but meeting the default BS i write on the paperwork "cooker clearences to be confirmed from MI" its CYA all day long.
re connecting hobs with a flexi, i dont do it, ever as a permananet job ( have done it in the past as an overnight connection while doing a kitchen refurb to allow customers use of the hob, but only when i have the MI to check its allowed and it is cut into a bit of worktop screwed to the unit and the unit tagged to the wall) cause im capable of bending and soldering, but that doesnt allow me to say "it cant be done"

 

[Syty]

Some of the cookers/ ovens must be connected by flexi, otherwise there is no access to connect or disconnect it

get ye point kirkgas but doesnt it say ye shouldnt fit any appliance without the mi,s ,thats what ive been lead to believe ,granted thats not always possible but i thought thats what the regs said

were on about hobs only mate not ovens

thought thats what i said as well!!!!!!!!!
but did say about future service guys querying it and writing a RIDDOR without checking they are right, and when doing service visits i commented what i write on the CP1 if i dont have the MI's

 

[GrahamM]

This is a prime example where a knowledge/understanding of MI's regulations and standards is important.

The MI's state a flexi may be use, but where fitting the hob above an oven that may produce external temperatures greater than 70°C this would not be permitted. A rigid connection would be required. (if a flexi is a must, I believe you may be able to use a heavy duty catering connection as they are rated to higher temperatures)
