Gas compression fittings - how to make good?
 
I'm about to connect the gas supply to my newly installed boiler and I
need some advice about the compression fitting used. As supplied it is
just a standard tap type connector with a fibre washer as the seal. Is
this sufficient? Do I need to wrap the threads in yellow PVC tape or
apply any sort of compound? Any other things I need to know?

TIA

See the Gas Fitting FAQ at

http://www.makewrite.demon.co.uk/GasFitting.html

I don't think I covered this in the FAQ.
I'm fairly sure that acceptable gas joints a

Soldered.
Threaded with gas tape or Boss white
Back-nut and long screw (a coupling method for steel pipe).
Compression where accessible.
I've seen gas appliances which have some sort of internal proprietry couplings
Usully involving a machined ball-cup or cone-cone mating.
Sometime you see ground flat faced couplings usually sealed with a
neoprene washer or maybe a fibre one.

I presume the coupling is like the last one listed in some way.

The installation instruction will say what to do it sounds like the
connection is BSP threaded with a washer at the end.

Is the connection on the boiler a threaded hole or a peice of threaded pipe?
Either way you will want to connect it with the CORRECT fitting.
A smear (and mean only a smear) of boss white may help if seal is made on the
washer against flat metal. Without seeing it I can't say for sure but it
is very likely the manufacturers intend you to seal on the washer NOT the
threads. Which make and model?

And get paid for it.

Any "competent person" can do gas work for themselves.

No, we've been through this. Please check earlier threads.

The law requires:

1) Anybody doing gas fitting work to be competent. it does not
define "competent"

2) an employed, self employed person or a firm doing gas fitting for
reward must be a CORGI member and, by implication, be appropriately
qualified.

3) In the case of work on properties rented out, all work must be done
by a CORGI fitter.

The law does not exclude somebody from doing gas fitting work on their
own property but does require them to be competent. The HSE has the
responsibility for enforcement and acknowledges that DIY gas fitting
does take place. It does not say that it is illegal and moreover
does not believe that it causes problems that require legislation.

(all together) .... Oh, no they're not!

(IOW, other people can, and they might even be more 'competent').

The Keston system kit comes with those for making the external
connections for water and gas. IIRC, it has a gas one inside too.
I think they're used where you want a joint which is suitable
for repeated dis/assembly but remains reliable.

I used to service my parents' Ideal Standard boiler (which was
replaced about 5 years ago at the age of 35 years old) and that
used them for the internal gas connections which you had to
disassemble each time you serviced it to get the burner assembly
out. They work very nicely for this purpose.

I had a couple of Baxi Bermudas in the past - where the gas connection used
a "Crane Joint" - which was a cast iron fitting having male and female
ground conical bits which were held together by a large nut. You had to undo
this to withdraw the burner assemble for servicing or repair operations.

is not 'competent' unless they have paid membership to the appropriate 'trade body' cartel....

Indeed. I wrote letters to MPs, government ministers and to the IEE
pointing out the phony statistics and the error of their ways, as did
others. The seed fell on stony ground.
