can any one help i am fittting a gas hob in the galley of my boat there is no gas instalation at present can lpg bottle be fitted directly below it in cupboard under the sink as this would be shortest pipe run or does bottles have to be in seperate locker out side of boat and is there a max lenght for run off 8mm copper pipe
 
The problem with this is always safely allowing any gas leak / escaping gas to get overboard instead of filling up the bilges and creating a very dangerous situation.

Lots of aurveyors and insurance companies would prefer an exterior locker which drains overboard.

Having said that, I do know of several people who have done hat you have suggested and they are still ok.

I imagine if you do this then a suitable gas alarm and leak detector would be essential. /forums/images/graemlins/wink.gif
 
Might I suggest that a spirit cooker (alcahol methylated spirits) would be far safer and cheaper to install. I accept that for constant use where you require quick kettle boil gas is better but to comply with safety requirements brings you in to a whole new ball park of costs. Alternatively use a portable cooker outside and a spirit cooker inside. A bottle inside the cabin is considered too dangerous, the bottle should be in a drained external locker. olewill
 
No, no, don't do it.

As part of our H&S training last year I went to a fire prevention demo in Bristol, it was very sobering, especialy the bit involving LPG. as its heaver than air it always 'Sinks'. They set up a simulated leak then ignighted a test sample, WOW!!
Suffice it to say, it is a very dangerous substance in confined areas.

The bottle must go in an outside locker and vent overboard, there are other recommendations as well, go here
Calor Gas for information, a must read site!

Key question is if there were an accident would your insurers pay up if they deemed your installation unsafe?
By the way I'd recommend installing an Alde bubble leak detector; very easy to use and ensures all the joints are tight
 
I concurr, outside in a locker with an overboard drain. You quite often get a smell of gas in a gas locker and you alway have some leakage as you install and remove the bottle.

If you are at all unsure about gas regs, would it not be better to get an expert to do the installation or go with the spirit stove option- I have had one of those and it was better than I expected
 
I once had the gas detector inside the (properly vented) locker go off. It was caused by the union at the bottle not being properly seated. If that leak had happened below decks it could have put the boat in orbit. Corgi fitters have tables telling them what size of pipe to use for a given length and appliance rating so there is no simple answer to that part of your question without more data.
 
Oddly enough - although I concur wholeheartedly with the vented locker side of the argument - I believe the Spring 25 was designed and sold with a gas cooker with bottle below which acted to gimbal the stove. I can't imagine how they got this past HSE etc
 
Lot to be said for it though, only one joint in the system, no piping, no flexible gas line, no taps...

OK, I accept tha tfilling your boat with gas and blowing yourself to smithereens is a slight disadvantage, but maybe such a system withmore modern gas detection techniques and a "bilge blower" under the cooker...

With respect, no. The key question is 'If there is an accident , how bad will your burns be?'

The answer is , in all likelyhood, 'Very'

If you want to instal gas, play it safe, put it in a locker outside. Best of all, get advice from a gas supplier.
 
Yup agree as I said befor get some advice from the Calor shop online.

Here is a quote from the site which really encompases all you are asking, & is well worth reading:

Many thousands of boat owners choose to use LPG for both cooking and heating as it is a very efficient and effective fuel and more convenient that the alternatives. A correctly installed and maintained LPG system is unlikely to make headline news, however "do it yourself" installation is no longer encouraged.

The installation of a gas system on the private vessel is not covered by the Gas Safety (Installations and Use) Regulations 1998. However, you have to take "responsible care" for the health and safety of yourself and other persons who may be affected by your acts or omissions at work under the Heath and Safety at Work Act 1974.

This means that you do not have to have the professional qualifications of a CORGI engineer but you do need to do the job in a "workman like manner", so you will need to read a copy of BS5482 pt3 and the references listed within. If you wish to do the installation yourself, then get it checked by a CORGI registered and "Competent" engineer who can issue a gas safety certificate. Your insurance company may insist upon it.

In addition to the sound advice already posted, if your boat is moored at Lincoln, the boat, if used for private purposes, must comply with the 2005 BSS requirements. These are described in chapters 7 and 8 of the 2nd edition BSS Guide which can be found on here on our website.

If anything is unclear, please get in touch with our office and we will do our best to advise.

I think that Cornish Crabbers (or one of the boats in that range) still have gimballed gas burners like that. Certainly the one that I looked at at the Boat Show a year or two ago was fitted with one.
 
I would agree with "Poter". Don't do it.

A couple of years ago I had to do a gas safety course (for dealing and delivering bottled LPG).
The course was being run by an "expert" with years of experience of handling LPG and delivering these courses. He had a rig to demonstrate what LPG does when leaked out of the system.
The rig decided to be a bit temperamental when he demonstrated it to the class., so he "fiddled" with it. The upshot was that he lost his eyebrows, eyelashes and most of his fringe.
It was a very effective demo. We ALL learned from it.
He admitted that he had been bloody lucky not to be seriously injured (and that we had been lucky too). There was a great deal of aggro caused to the course organisers because of this incident.
 
I think it's a pretty good system and at least as safe as having a pipe leading from a vented external locker. In both cases you have one union at the cooker. With the directly attached bottle you have no pipes which could leak into the bilges and no other joins. Changing bottles involves lifting the whole unit outside, obviously, but this kind of setup only appears on small 1 or 2 ring cookers.

To my great irritation my current boat had this kind of arrangement replaced some years ago with a pipe leading to a gas bottle in an unvented cupboard inside the boat. Doh! The worst of both worlds.

Does anyone happen to know where you can buy 2 burner gimballed stoves which attach directly to the bottle, so I can get back to the old arrangement?

..the potential for a high-pressure leak of liquid propane/butane within the cabin space, the potential for an explosive container in fire or indeed a jet-powered container in fire.

One volume of escaped liquid propane/butane will generate, very approximately, 250 volumes of gas.

LPG cylinder in fires are recorded as shooting high into the air. Fire-fighters usually attempt to tackle fires where LPG cylinders are involved from 'afar'.

The sources for our standards are BS 5482-3 now known as PD 5482-3 and ISO 10239. We trust these codes describe 'safe' LPG systems.
