4.3.9.1 Using the LPG cooker

Follow these instructions to safely use the LPG cooker. 

Ventilation

Appliances which burn fuel consume oxygen and discharge combustion products into the boat. Good ventilation is essential when an appliance is in use.

  • Never use the LPG cooker for heating the boat.

  • Never cover the ventilation openings.

Lightning the LPG cooker
  1. Ignite the burner by pushing the knob down. Then turn the gas knob to its maximum position, listen for the gas flow, and hold the knob down.

  2. Light the flame by lighting the burner with a match, lighter, or built-in ignition system. Keep pushing the knob for 10 seconds. If released earlier, flame sensor might shut down gas.

  3. Adjust the flame by turning the knob to the desired size.

  4. Turn off the LPG cooker by turning the knob back to its original, off position to stop the gas.

Valves
  • Close the valves on the supply pipes and the container valve when the appliance is not in use.

  • Close the valves before refuelling and immediately in an emergency.

  • Check that the appliance valves are closed before opening the container valve.

  • Keep the valves of empty cylinders closed and disconnected.

  • Fit the protective covers, caps or plugs.

  • Store spare or empty cylinders on the open deck or in drained areas designed for the purpose.

Replace the regulating valve every 10 years.

The valve contains a thin rubber diaphragm which eventually dries out or swells up. If the diaphragm breaks, gas can escape from the cylinder with full pressure into the system, thus causing a fire. 

Inspections

System has pressure gauge installed to LPG cylinder connection. LPG system shall be checked for leakage before each use.

  • Close appliance valve.

  • Open LPG cylinder valve.

  • Allow indicated gauge pressure to stabilize.

  • Close LPG cylinder valve, and observe pressure gauge reading for 3 min.

  • Pressure gauge reading should remain constant if no leak in the LPG system is present.

  • Gauge does not provide an indication of liquid LPG remaining in the cylinder, only its vapor pressure, which is a constant at any given temperature.

If LPG leakage is detected or suspected, the following action shall be taken immediately.

  • Shut off the LPG supply at the main supply valve.

  • Extinguish naked flames and other ignition sources (heaters, cooking appliances etc.).

  • Do not operate electric switches.

  • Evacuate the area if possible.

Inspect the hoses and pipes in the system regularly, at least once a year.

  • Replace parts if there is any deterioration or damage.

  • Replace the LPG hoses outside the cabin every second year, and the LPG hoses inside the cabin every 3 to 5 years.

  • Check the flue ducts at least once a year.

    • Replace the flue ducts if there is any deterioration or damage.

  • Check the connection gaskets for the regulating valve always when containers are replaced, and replace the connection gaskets annually.

  • Never use an open flame when detecting leaks.

  • Do not use solutions that contain ammonia for manual leak testing.

  • Never smoke or use open flames when a gas container is being replaced.

  • lf a leak is detected, shut off the main LPG supply valve and do not use LPG appliances.

  • Do not use an installation that has leaked until it has been inspected and repaired by a competent person.

Maintenance

For the LPG cooker maintenance schedule and instructions, see the manufacturer's manual.

  • Keep the LPG container in a space designed for it.

  • Never leave the boat unattended when LPG appliances are in use.

  • Do not smoke or use open flame when replacing LPG cylinders. Close cylinder valves on empty cylinders before disconnecting for replacement.

  • Do not modify the craft's LPG system. lnstallation, alterations and maintenance shall be performed by a competent person. Have the system inspected at regular intervals or as required by national requirements.

  • Make sure that you always have free and rapid access to the LPG system.

  • The ambient temperature for LPG systems is –20 - +60°C.

Never use a wrong type of fuel in the cooker as this may damage the cooker.
