What must each LPG appliance contain in regard to supply lines from the cylinder locker?

Each LPG appliance must contain its own low-pressure supply line to ensure safe and efficient operation. Low-pressure supply lines are essential because they are designed to handle the reduced pressure of gas that is required for appliances to function properly within the system. This setup allows for the safe and regulated distribution of LPG from the cylinder locker to each individual appliance, ensuring that each unit receives the appropriate amount of gas without risk of overpressure, which can lead to malfunctions or hazardous situations.

This requirement is also crucial for compliance with safety standards, as it minimizes risks associated with leaks and ensures that any potential issues can be isolated to a specific line, rather than affecting the entire system. The regulation of low-pressure supply lines is a key aspect of maintaining safety and efficiency in LPG installations.
