Someone more knowledgable than me will come along in a mo but I didn't think CORGI covered boats. It does however make alot of sense to have someone do it who knows whats what. The last thing you want is a dodgy gas installation on a boat!
You can change it yourself if it is within your competence. Unless you are on the Inland waterways there is no requirement for any inspection or testing but it would be strongly advised that it is. (at the very least test all joints with a leak detector)

you must be corgi regestered or a compentent person.
[/ QUOTE ] To work on your own privately operated boat you do not need to be Corgi Registered.
As noted above the Corgi registration ceased to be on 1st April anyway.
Hi all I would define a compontent person would be a heating engineer who knows how to carry out leakage test smoke tests etc and is aware of good practice in installing gas appliance.
But be aware that if you do not install it properly and there is a fire or explosion be prepared for a spell in prison.
I have worked on oil gas burners for a long time and would not take any chances.
Flexible pipe between cooker and fixed pipe or more fixed pipe? Do you have a bubble test point already fitted etc.
Replacing flexible pipe is pretty basic and should be done every few years anyway. Fixed pipe is somewhat harder but still not very hard, bearing in mind the consequences of lousing it up and having a leaky joint.
There are two pressure tests that should be carried out. One with air at a specified pressure above the normal gas pressure, the other with gas at a slightly reduced, but specified, pressure.
Both require there to be no discernible pressure drop in 5 minutes!
Both are described in the old Corgi Handbook and presumably in whatever now replaces it.
They are also both described by Philip Stevens in the link I gave earlier.
VicS is not wrong - I was Corgi registered for many years and passed the elements for Butane/Propane before I let it lapse a couple of years ago.
As a Consultant I didn't need to be registered, even when designing 6" gas main installations and laboratory distribution systems and witnessing/signing-off gas test certificates! But I did find it useful to have - had to do a few domestic gas jobs/installs (usually for friends or family) a year, just to convince the assessor (Who on one occasion borrowed some of my old MSc and HND course notes as he was doing his HND)! Needless to say I passed that assessment!
Of course, whilst it says gas work must be undertaken by a competant person (which would be tested in court), we have to be sensible.
Replacing a spent cylinder, regulator or a flexible hose for that matter could constitute gas work! But a simple test with old fashioned soap and water should be sufficient, the gas cylinder only has a limited (yes but still dangerous) capacity, unlike mains gas! It and the hose should also be located either externally or in a ventilated enclosure.
I am not saying that gas work should not be regulated, I do agree with this, but common sense must surely prevail! /forums/images/graemlins/ooo.gif
Best you check your facts - you do not need to be CORGI registered (now Gas Safe ) to work on your own small boat gas installation provided it does not require a BSS certificate.

The cylinder connection is one of the biggest sources of onboard leaks according to some BSS surveyors especially with calor Butane.
Seems a surprising number leave the same sealing washer in use year after year not realising they get given a new spare with every refill!!!!
My Dad, who had been a plumber for 50 years & Corgi Registered for the latter part of his long career & early part of his active retirement, used to test for coal gas leaks with a lit match! /forums/images/graemlins/laugh.gif
Doesn't pay to waste time though! /forums/images/graemlins/grin.gif
PLEASE NOTE - I am not recommending this practise, just pointing out that risks & dangers can be managed successfully with common sense & understanding.
Hi lensman I think you are not treating this seriously.
I lost a good friend due to a gas explosion on a boat he took 3 days to die.
I have commissioned industrial boilers and burning equipment for over 40 years so when i say leave the pressure test on for 30 min that is what i mean start the test have a cup of tea when you return you can be satisfied that it is safe.
