running gas pipework for hob and gas cooker

[ChrisR]

The Judge would then throw the book at Chris!

So, wrong again Tony! There isn't a book and judges aren't stupid.
There are situations every day where pro engineers have to, or choose to, apparently infringe one regulation or another. We know the reasons why the hose shouldn't be used (heat) so if we avoid the problem then we can show that our method is "as safe as" the standard measure.

In the same way, you would be in trouble if you rigorously applied a regulation where it were clear that to do so would be dangerous.

Boiler mountings is a simple example. Just because they're supplied with a boiler doesn't guarantee their adequacy, and it doesn't always say "use your judgement". DIA's pipe is another example.

Just because Chris thinks its OK does not mean that it is!

No but it would take a court to decide - we bear the responsibility for our decisions. We are not only entitled to make them, it's our obligation to make an engineering assessment of risk.

By the way on the corgi website it say that pipes behind DFE's have to be kept below 1000 degrees. 999 OK then? Copper wouldn't quite be molten!

Here's one for the domestic bods.

live chat with Mike Thompson.

A Moderator said:Lee Martin wants to know: "What is the maximum size
gas pipework that I as an installer can work on with a
non-industrial qualification?"

Mike Thompson answers

The assessment is restricted to a maximum pipe size
of 150 mm.

Have I missed something lately or is that a tad big.

 

[kevplumb]

you and me too mate

28 was the limit for domestic
unless the powers that be have changed the rules (again)

 

[HARALIAN]

Gotta get that huge gas bottle for the 150mm fittings.

there is nothing wrong with fitting a hob with a flexi hose complying to bs669
if it is to be fitted above a drawer pack as there is no heat to hurt the hose as for an iso the bayonet acts as one so no need there but most times it makes for a harder install and easier for the customer to mess with when they change there worktops or drawer pack

AS I read it.

The flexible must be hard wird to a rigid pipe, not with a bayonet fitting.

May be wrong again as not my field

The BS (can't remember the number) was revised last year, I had a look at it in the library, it says only portable/moveable gas appliances may be fitted with a flexible hose. Of course MI can always override this, but my guess is in time MI will be changed to reflect this.

 

[Agile]

That revision on the BS is probably what prompted the web site I saw saying hoses were prohibited since late 2004. Most MI that I see for hobs only say that the hob must be installed in accordance with the local regulations by a competent person.

Kevin, I had always been under the impression that 28 mm was the largest commercial pipework I could work on without a commercial pipework certificate. But...

Latest CORGI mag has an article where it says 28 mm unless its a copper pipe in which case its 35mm. !!!

Now where did that increase come from ???

nearest steel to 28mm is 25mm next up is 32mm.

For the record 20m of 25mm steel will discharge 6.30m³ whereas the same length in 28mm is only 5.9m³

eh?

Hi
Weve had builders in and they had a CORGI guy come and move our gas pipe for the free standing oven and put a bayonet connection on the end.
I have the oven and the flexi bayonet pipe.
Presumably I am allowed to make the connection between pipe and bayonet connection as it is fool proof. Am I allowed to make the connection between the flexi pipe and the oven or does that need to be corgi too? It just looks like a screw fitting although maybe there needs to be some kind of sealing stuff [like hawk white for plumbing joints?]
Thanks
chris

domestic rgi (ccn1) can now work on U16 35mm outlets if:
they have a copy of/access to IGE/UP/1B/edition 2
or (according to Corgi)
Have recently done ACS CCN1, supposedly 35mm purging is now included.
