Local isolation requirement for appliances

[Masood]

Having a brain fade moment guys - is it an actual requirement to have an isolation valve for individual gas appliances, or just good practice?


I'm certain it's a requirement but I can't find evidence to back it up. Someone is arguing that If the ECV is within easy reach it's just good practice and not a requirement...


Please provide a source of evidence if you can rather than an opinion. Important to prove this one way or another, as customer is a stickler for doing things by the book.

From current BS 6798:2014 Specification for selection, installation, inspection, commissioning, servicing and maintenance of gas-fired boilers of rated input not exceeding 70 kW net

7.5 Gas supplies and pipework
7.5.1 First and second family gases
...
7.5.1.5 A boiler shall be provided with an adjacent isolating valve if this is not already supplied with the boiler.

26 (6)
No person shall install a gas appliance without there being
at the inlet to it means of shutting off the supply of gas to the appliance
unless the provision of such means is not reasonably practicable.
Guidance 26(6)
198
The means of shutting off the gas supply to an appliance may
comprise either a conventional isolation valve, or other effective means, eg a
self-sealing plug-in connector (commonly used on cooker installations) or a
screw down restrictor elbow (such as used on gas fire installations). A shut-
off device at the inlet to a gas appliance is regarded as part of 'installation
pipework' for the purpose of these Regulations (see definition in regulation
2(1))

199
The shut-off device required under this regulation assists tightness
testing of installation pipework and allows an appliance to be
isolated/disconnected in case of an emergency, eg if the appliance develops
a gas leak or otherwise becomes dangerous. Although the regulation
recognises that provision of a shut-off device at the inlet of an appliance
might occasionally be difficult, there will be few, if any, situations where this
is not reasonably practicable

Basically we are down to, if you can fit one-do, if you can't-doesn't matter
Gas fires mostly come with restrictor type taps, cookers have flexible and plug, and we are back on hobs really.

 

[AWheating]

Depends on what you think the reasonably practicable means. i think there are very few situations when you cant fit one, if manufacturers instructions require one (which most do) then you cant fit without. cant think of any hob install that one cant be fitted, if the pipework needs to altered then so be it, the customer not wanting to pay for it to be done correctly is no excuse.

At least the lads on here give good advice,looking at fb groups half the retards on there would be ridiculing right now ,makes me feel how more civilised this forum is

We have just recently replaced some electric ovens fitted under units, which are deeper than the old existing, and have to do serious modification to the hob pipe work to fit the new ovens,there was not enough room for the pipes to run at the back of the ovens, there were drawer units either side with deep drawers, so no valves could be fitted.

Cheers all, just what I needed! To be clear, customer (landlord, who I work for direct), has no problem with things being done right, and he trusts me.

The agent claimed that I was making work for myself and there was no requirement to have isos, because his team refurbed the kitchens and I noted this on the CP12.

Now the landlord is getting me to rectify, and the agent will be paying me out of what he charged for the kitchen works, so he's unhappy at losing some of his profit...

You have always had to fit an isolating valve to every appliance as far back as i can remember.
The usual agents knowing everything about feck all.

Btw test points before every appliance is coming to a screen near you soon

already asked on that one,told its not mandatory just recommended

Didn't that come into force, then was scrapped, and is now under discussion to see whether thry want to bring it in after all?

 

[tamz]

I'm not sure Mas I'll ask Kirk

iso valves in/ under plinth of cupboard most suitable or another smaller oven should be fitted.
