All LPG installations must meet the testing requirements of BS 5482 Part 3, in so far as they cover gas soundness, flue spillage and burner flame pattern requirements. Meeting these requirements will minimise the risks of gas leaks into your boat and the build-up of combustion products which may be toxic to you and your crew. All of these tests must be completed by the BSS examiner during the examination, where applicable, and it's very important to remember that your boat must have sufficient quantities of gas and water and an adequate supply of electricity on board in order for these to take place.
