Frightening, utterly frightening. Regulars will have noticed that I very rarely engage in such threads. They know pack drill and others like MTBM have already said it here before - engage a competent person to undertake the works.
Gas systems cannot afford to be bodged.
Gas systems should not be installed to chit-chat standards (there will be no defence in court when the proverbial hits the fan)
Gas systems should not be installed to BSS requirements - our requirements are not installation standards, they are indicators that the navigation authorities wish to see for the minimum acceptable condition of a system post-construction.
Gas systems absolutely must be installed, fully compliant with either the latest versions of ISO 10239 or PD 5482:3 (previously known as BS5482:3).
These are expensive standards to buy so why not follow the advice of Chris Py, copies of British Standards can sometimes be obtained from some public libraries or some other limited options, but it will take a lot of effort. However again as MTBM wisely and succinctly pointed out, the properly registered, professional gas fitter has invested in training and assessments and copies of standards and retaining and reassessment and updates and proper tools, so that the average boat owner does not have to.
From memory, and although I am the BSS incident statistics compiler I may have forgotten some incidents, all the bar two of the last few years of gas explosions from installed gas systems and where the cause was identified, have been because incompetent people have fiddled around and bodged. Again from memory, without going back into the depth of the files, all gas explosions on boats where there was someone aboard, have resulted in death or injury. So far this year, two people have been hospitalised by gas explosions.
LPG installation is not an area to experiment with or one can be treated lightly. It is a deadly serious matter, there is no room for error.Nearly getting it right is a too dangerous place to be.
So Dean, do you plan to put your family's safety (and the safety of nearby people) in what you admit to be your less than expert hands, or will you have a rethink about what in this world is really worth investing in?
My hat and coat is very firmly on, I have a report to write about the 5 carbon monoxide incidents and 31 fires on inland boats so far this year.
