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. Gas cylinders (including 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.
- The locker 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.
WARNING
Fuel-burning naked-flame appliances use up the oxygen in the cabin and release combustion
products inside the vessel. Proper ventilation is necessary:
Open the deck hatch or porthole located nearby as well as 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 off 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.
