IWEMA enterprise is a wholesaler / manufacturer of LPG equipment.
Because of the broad range of legislation in Europe we decided  to conform our systems to the most tight legislation.
To get the most safe systems we use the most tight regulations for the installation in our “code of practice”.

The most important guide lines are:

- All parts which need a E* 67r-01**** approval in cars also need these approvals when used in vessels.
- The valve box on the tank must have its own ventilation to the outside of the vessel, 50 cm above the water line.
- The high pressure LPG supply must be made from fixed pipe work.
- Connections in the pipe work with a pressure above 1.2 bar must be made in a locker if possible.
- The extended filler must be on the outside of the vessel, so gasses can’t enter the vessel when connecting or disconnecting.
- The parts of the LPG system must be protected against the marine environment.
- All LPG parts must have a minimal distance to hot engine parts of at least 25 cm.
- Right and left above the exhaust is a 45 degrees safety area. All vent pipes must end at a distance of at least 25 cm in horizontal level of the safety area.
- Gas sensors must be installed in the tank compartment (lockers) and in the engine bay.
- Ventilation blowers must be installed in the tank compartment (lockers)  and in the engine bay.
- The LPG tank, fuel pipe and vaporiser must be closed automatically when the engine stops.
- Before starting an automatic safety procedure has to take  place, which vents the engine compartment and the tank compartment (lockers).
- After installing all parts of the LPG system must be accessible for maintenance.
- The LPG system must be tested every 6 months.
