IV. GAS INSTALLATION
General Information
- Pressure for use: 30 mbar (see indication on the label in the gas locker and on the regulator valve)
- Vents to use for the evacuation of burnt gas: hatch above the cooker and companionway
- Do not obstruct quick access to the elements of the gas installation (cylinder locker, shut-off valve).
- Regularly inspect the hoses at least once a year and change them if damaged, if the expiry date is
exceeded, or five years after the manufacture date printed on the hose.
- Valves attached to empty cylinders must be closed and disconnected. Protective covers, caps and
plugs must be kept in place. Reserve cylinders must be kept in housings or lockers for LPG
cylinders with ventilation to the exterior, or stored at the exterior of the boat, protected from
weather and mechanical damage, and in such a way that any leaking gas can only escape to the
exterior of the boat.
- Lockers for LPG cylinders must not be used for the storage of any other equipment.
- Ensure that the gas cylinder and regulator comply with the requirements of the cooker (flow rate,
pressure, type of gas) and with the regulations in force in the country where it is being used.
- Make sure that all valves are closed when replacing gas cylinders.
Operation of the LPG system
- The valves of the supply lines and cylinders must be closed when the devices are not used or
before filling, and must be immediately shut off in case of emergency.
- The valves of the appliances must be closed before opening the cylinder valve.
Fuel-burning naked-
flame appliances use up the oxygen in the cabin and release combustion
products inside the vessel.
Proper ventilation is necessary: open both the deck hatch or porthole
located nearby and the companionway when the appliances are in operation.
- The cooker is suspended and can therefore be used when under sail. However, limit its use when
large angles of roll or heel are likely.
Checking the system
- The LPG system should be checked for leaks before each use as follows:
- Close the valve of the appliance, open the LPG cylinder valve, allow the pressure of the pressure
gauge to stabilise, close the valve of the LPG cylinder, check the pressure indicated by the
pressure gauge located near the cylinder for three minutes. The pressure indicated by the pressure
gauge should be constant if there is no leak in the system.
- Information: the pressure gauge does not give an indication of the quantity of liquid LPG remaining
in the cylinder but only its vapour pressure, which is a constant at a given temperature.
- If a leak of LPG is detected or suspected, immediately take the following steps:
- Cut of the supply at the main supply valve(s).
- Extinguish any naked flames and other sources of combustion (heating appliances, cooking
appliances, lights, etc.)
- Do not operate any electrical switches.
- Evacuate the area, if possible.
WARNING
● Do not use an installation with a le
ak before it has been inspected and repaired by a competent
person.
