The installer of the LPG-system shall:  possess the competence and expertise necessary for the proper installation of the LPG-system;  have a quality control system that ensures that the installation of the system meets the requirements of this standard;  maintain records of the leak test (see X7.1X) and start up operations that are carried out after the installation The manufacturer of the system shall supply installation instructions to the installer of the system. NOTE An example of an installation certificate is given in XAnnex F. 5.3 1Other connections to the fuel system Other LPG systems (e.g. for cooking and heating appliances) which are connected to the LPG propulsion system, shall be adequately protected against unintended gas escape and the operation of the LPG propulsion system shall not be affected. Cooking appliances shall be connected to the vapour phase of the fixed container or cylinder and shall be adequately protected against unintended gas escape and the operation of the LPG propulsion system shall not be affected. SIST EN 15609:2009

Containers, regulators and safety devices shall be secured against any movement that is expected to result from marine service. The container shall be installed so that there is no metal-to-metal contact, other than at any permanent fixing points. A fixed container shall not be directly in contact with the floor and a minimum of 20 mm of space is required. SIST EN 15609:2009

NOTE Hatches for inspection or maintenance of fuel tanks may be covered by uncut carpet, provided that all tank fittings can be inspected and maintained through other openings. If the container is secured to the craft by a container frame and/or container straps, the container shall be installed according to the requirements of XAnnex AX or XAnnex BX as appropriate. Supports, chocks or hangers shall be separated from the surface of metal containers by a non-metallic, non-hygroscopic, non-abrasive material unless welded to the container. Foam shall not be the sole means used to secure containers in place. Where foam is in contact with the container, due care shall be taken to avoid corrosion. Metallic containers within the hull shall be installed with the container bottom no less than 25 mm above the top of the bilge pump inlet or the bilge pump automatic float switch, if fitted. 5.5.3 Cylinders 5.5.3.1 All cylinders Cylinder(s) shall be attached by a dedicated system to the structure of the craft as described in XAnnex CX. Cylinders, valves and pressure regulators shall be installed so that they are readily accessible. Copper-base alloy fittings may be used with aluminium cylinders if protected by a galvanic barrier. Where there is no means to indicate the liquid level of a cylinder, provision shall be made to store filled spare cylinders of equivalent capacity. Provisions for storage of unconnected LPG cylinders, whether filled or empty, shall be the same as for cylinders connected to the system. Cylinders designed to be used on their sides (e.g. FLT type) shall be secured at the correct rotational angle (to ensure correct, liquid off-take and relief valve position). 5.5.3.2 CCylinders in vapour/gas phase For cylinders working on vapour/gas, the low-pressure regulator shall be in accordance with EN 12864 and installed just after the cylinder’s valve outlet.
If several cylinders are simultaneously supplying the engine, an additional pressure-regulator may be installed as close as practicable to the cylinders.
 remote (at least 250 mm) from the engine exhaust system;  protected from blockage by virtue of its position or other means;  located at least 500 mm from any hull opening to the interior of the craft All hoses or metal piping penetrating the locker walls shall be sealed at the wall so as to maintain gas tightness to the craft interior. 5.5.5 IInstallation of more than one container If more than one container is connected to the engine fuel line, the containers shall be installed so that no hydrostatic pressure build-up can take place in the fuel line and that LPG cannot flow from one container into another. This can be achieved by installing a non-return valve downstream of the  remote-controlled service valve; or
 manually operated valve on each container and a hydrostatic relief valve in the delivery tube, downstream of the non-return valves. An adequate filter system shall be placed upstream of the non-return valves to prevent fouling of the non-return valves. See Figure E.1. A non-return valve and a hydrostatic relief valve is not required if the back-flow pressure of the remote-controlled service valve or the manually operated valve, in the closed position, exceeds 500 kPa. See Figure E.2. In this case, the power supply to the remote-controlled service valves shall be wired so no more than one remote-controlled service valve on the container can be open at any one time. The overlap time to allow switching from one container to another shall be limited to two minutes. Each container shall be provided with its own 80 % stop valve, if required. 5.6 Components fitted to the fixed container 5.6.1 General requirements These requirements do not apply to cylinders. The components on and in the container shall be installed under the responsibility of the holder of the bonfire test certificate as described in EN 12805 or ISO 20826. SIST EN 15609:2009

5.6.7 Gas-tight housing A gas-tight housing shall be fitted over the container fittings unless the container is installed on the main deck and the container fittings are protected against dirt and water. The gas-tight housing shall be vented to the outside of the craft via a venting tube. The ventilation opening of the gas-tight housing shall be provided with adequate protection to prevent the ingress of water. It shall not be directed at a heat source such as the exhaust. The venting tube shall have a minimum clear cross sectional area of 450 mm2. If a gas tube, other tube or any electrical wiring is installed in the venting tube, the clear cross sectional area shall also be at least 450 mm2. The venting tube shall be securely attached to ensure a gas tight connection. 5.6.8 Pressure relief device The pressure relief device shall be fitted in or on the container so that it discharges overboard directly or via the gas-tight housing, if fitted. SIST EN 15609:2009

A flexible hose complying with the requirements of EN 12806 is a preferable alternative to copper gas piping. Rigid pipe shall not be used between parts which can move relative to each other, e.g. between a huII and a flexibly mounted engine.
Gas pipes shall be supported by fixing devices or other means, such as inside vented, non-metallic, supported conduit or piping, to prevent chafing or vibration damage.
Metallic gas pipes shall be secured so that they are not subject to excessive vibration or stress.
Flexible hoses and non-metallic gas pipes shall be secured so that they are not subject to excessive stress. Gas pipes or flexible hoses shall be:  fitted with a protective sleeve at the fixing points in order to prevent abrasion;  secured by clamps to the main structure of the craft or to parts rigidly connected to the main structure of the craft Piping and hoses shall not have direct contact with metallic parts of the craft structure. For copper or stainless steel piping, fixing devices shall be pipe rings spaced at intervals not exceeding 0,5 m. For piping of other materials, the fixing devices shall be spaced at not more than 1 m.
The fixing devices shall be corrosion resistant, non-abrasive, designed to prevent cutting or other damage to the piping and compatible with the pipe material. Metallic piping routed through engine compartments shall be protected by conduit or trunking or be supported by non-abrasive attachments, which are no more than 500 mm apart.
Piping shall be routed at least 30 mm away from electrical conductors, unless the piping passes through a conduit with no joints, or the conductors are sheathed or in a conduit or trunking in accordance with
EN ISO 10133 and EN ISO 13297.
Metallic piping shall be at least 100 mm from exposed terminals of electrical devices or accessories. Piping and hoses shall be installed as high as practicable above the bilge water level. Piping and hoses passing through bulkheads intended to maintain watertight integrity in the craft at the level of penetration shall be sealed by suitable materials or fittings at the point of penetration. Piping and hoses shall be protected from abrasion or chafing at the point where they pass through walls or bulkheads. A grommet shall be fitted to the hole where piping or flexible hoses pass through the structure of the craft. The outside diameter of the hole through the structure shall be at least 1,5 times the diameter of the pipe or hose that passes through it. SIST EN 15609:2009

Welded or brazed joints are permitted, provided that such joints are limited to the factory-assembling of components.
The melting point of materials at welded or brazed connections shall be not less than 450 °C. Solder should have a melting point of not less than 450 °C. The design pressure of the couplings shall be the same or higher than that specified for the gas pipe.
Distributing blocks shall be made of corrosion resistant material. Fittings for connections and joints in piping shall be metallic and of any of the following types:  hard soldered connections;  cutting-ring fittings;  compression fittings made of copper alloy with solid or thick-walled copper rings on copper piping;  stainless steel rings on stainless steel piping The wall thickness of the ring shall be greater than or equal to 0,5 mm and a jointing compound shall not be used on compression or flared fittings. Fittings shall be galvanically compatible with the metallic piping to which they are connected. Gas pipes shall be connected by appropriate fittings compatible with the material of the pipe. End-connecting fittings shall be of corrosion-resistant material such as brass or stainless steel. Brass end fittings and cutting rings shall not contain more than 15 % zinc. Where cutting-ring fittings are used in conjunction with copper piping, a brass insertion sleeve and brass cutting ring shall be fitted. All components shall be matched, i.e. shall be of the same series. The number of joints shall be kept to a minimum and shall only be made in locations where they can be inspected.
Supply piping shall be made up with as few fittings as practicable.
Joints and fittings shall be readily accessible. All joints and connections in piping and hose in the systems shall be made such that no undue stress is created at the fitting. Except for bulkhead fittings, there shall be no joints or fittings in piping that passes through engine compartments.
There shall be no connections in any enclosed compartment with the exception of:  engine space;  connections within and on the gas-tight housing;  connection between the piping or flexible hose and the filling unit if this connection is covered with an LPG compatible sleeve that vents any leaking gas directly to the outside of the craft SIST EN 15609:2009

If the LPG-system requires a return pipe or hose to the container, the connection on the container shall be provided with a non-return valve. Hose clamps, if used to secure cylinder-locker vent hoses, shall be made of corrosion-resistant material, such as stainless steel of type 18Cr 8Ni, or equivalent, and be reusable. Hoses carrying LPG under pressure shall be provided with re-usable mechanical connections. Hose connections shall be stress free, i.e. not subjected to tension or kinking under any conditions of use. 5.7.3 Remote-controlled shut-off valve 5.7.3.1 Fixed container - liquid phase A remote-controlled shut-off valve shall be installed in the piping from the container to the pressure regulator/vaporiser, as close as possible to the pressure regulator/vaporiser.
