IV. GAS INSTALLATION
General information
- Operating pressure 30 mbar (see indications on the label in the gas locker and on the
regulator valve).
- Ventilation openings to be used for the evacuation of exhaust gases: hatch above the
cooker and the 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 you observe any
deterioration, if the expiry date has been exceeded or within five years of the date printed
on the hose.
- The cylinder shut-off valves should be closed and disconnected. Protection hatches,
covers and caps should be kept in place. Reserve cylinders should be stored in the LPG
cylinder housing or lockers with a ventilation circuit leading towards the exterior, or stored
at the exterior of the vessel, protected from weather and mechanical damage and allowing
any gas leakage to evacuate towards the exterior.
- LPG cylinder lockers must not be used for the storage of any other material.
- Ensure that the gas cylinder and regulator are in accordance 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.
Operation of the LPG system
- Supply system shut-off valves and cylinder valves should be kept closed when the
appliances are not in use, before filling and immediately in case of emergency.
- Appliance shut-off valves must be closed before opening cylinder valves.
● 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 devices are in operation.
- The cooker is mounted on gimbals and can therefore be used when the vessel is under
way. Nevertheless, limit use when wide angles of roll or heel are likely.
Checking the system
- The LPG system should be checked for leakage before each use in the following way:
- Close the shut-off valve of the appliance, open the valve of the LPG cylinder, allow the
pressure indicated on the pressure gauge to stabilize, close the valve of the LPG cylinder,
observe the pressure indicated by the pressure gauge located near the cylinder for three
minutes. The pressure indicated by the pressure gauge should remain constant if there is
no leakage in the system.
- Information: the pressure gauge does not indicate the quantity of liquid LPG remaining in
the cylinder, but only its vapor pressure, which is a constant at a given temperature.
