Hi All
SWMBO has got her heart set on a gas double oven to replace our old elctric
fan oven, we already have a gas hob so the gas supply is there already, how
much trouble is it likely to be to fit? The last time I did any gas fitting
was with 3" iron pipe in a boiler house (20 years ago). Are there likely to
be fittings designed to supply both hob and oven easily available or is it a
case of just finding a BSP tee and flexible connector. I guess I'm asking
if this has been standardised - in our previous house I just fitted a
bayonet fitting.

Flexible hoses are for "mobile" or non fixed appliances. Fixed
appliances, eg oven units/hobs/gas fires/central heating boilers
should be fitted with rigid pipework.

I've got a visitation from the CORGI inspector tomorrow so I'll quiz
him.

OK. He came and went after giving me a stern lecture about making sure I was
proof against the complaining customers from hell (they are on the
increase).

So I asked him.
He says the manufacturers instructions must be followed.
I said I was fairly sure the 'book' said the inlet gas connection is
1/2" bsp female iron. and 'all work to comply with BS 6172' (IIRC).

He quizzed me about the regs for cooker hoses.

Bottom line in his opinion: The only way to connect a built in oven is with
a flexible hose to BS 669-1. He says this is what the standard says 'for
ovens' (without regard to whether built-in, build-under, slot-in or
free-standing).

So I asked about "Say I'm doing a "Landlords'" and I come across a hose
supplying a hob". He said OK if
1) Hangs in a neat unstrained U.
2) Not subject to mechanical wear or abrasion.
3) Not in contact with anything that could be 70C+

I said it was unlikely that people would give up the cupboard space
underneath. He agreed saying that in his view pots and pans might cause
damage to the hose.

I asked about the unsafe procedure categories:
We agreed AR (At Risk) if (1-3) above were not being complied with.
ID (Immediately Dangerous) if significant damage had already occured even if
(1-3) were being complied with.
