What requirement is shared between ANSI Z21.50 and ANSI Z21.11.2a?

The shared requirement between ANSI Z21.50 and ANSI Z21.11.2a involves safety pilot requirements. Both standards ensure that gas appliances are equipped with safety features to enhance user safety. Specifically, these safety pilot requirements are designed to prevent unintentional gas flow and ensure that the appliance can be shut off in the event of a malfunction or failure of the ignition source.

This focus on safety is critical in maintaining proper operation and preventing hazardous situations, ensuring that appliances adhere to high safety standards in their design and functionality. Each of these standards has specific protocols for the inclusion and operation of safety pilots, thereby raising the overall safety measures in gas appliance operation.
