After a shutdown, the ability to restore fuel or power should require a deliberate, human action. Requiring manual resetting ensures that a qualified person has verified the situation—checking for gas leaks, confirming ventilation and safety controls are functioning, and ensuring maintenance or repairs are complete—before re-energizing the system. If resetting happened automatically, the system could restart during a hazardous condition or after a fault has not been properly addressed, creating a real risk of fire, explosion, or electrical hazards. Verification or inspection are important steps in the safety process, but they don’t by themselves re-enable the system; the reset itself must be done manually to ensure intentional, supervised restoration. Therefore, manual resetting is the correct requirement.
