PD 5482-3 is a Published Document that covers gas burning installations in boats, yachts and other vessels1) of up to 24 m in length, using liquefied petroleum gas (LPG) from either cylinders stowed on board or, in the situation of a fixed shore bulk supply, the onboard aspects of the gas system, operating at 28–30 mbar2) for commercial butane and 37 mbar for commercial propane. It does not cover use of LPG for propulsion of vessels for which guidance is given in LPGA Code of Practice No. 18 [4].
It gives guidance on selection of materials, appliances and components, design considerations, installation requirements, inspection, and testing, and preparing instructions for the user. This part of this Published
Document gives recommendations for selection and maintenance of room sealed appliances and non-room sealed cooking appliances. It is intended for new installations, but recommendations for existing installations are given in Annex A.
PD 5482-3 does not cover installation of bulk supplies of LPG or portable LPG-burning appliances, or appliances with directly attached gas cylinders such as portable self-contained camping stoves or portable gas lamps. Neither does it cover the installation of LPG generators.
