What must be done to ensure a gas appliance is operating within safety limits?

To ensure a gas appliance is operating within safety limits, regular inspections and testing for leaks are essential. This process helps identify any potential issues with gas connections and ensures that there are no gas leaks, which can pose significant safety hazards, including the risk of fire or explosion. Routine inspections also help verify that the appliance is functioning correctly and efficiently, thereby reducing the risk of carbon monoxide buildup and ensuring that emissions remain within acceptable limits. Testing for leaks can involve various methods, such as using soapy water or specialized leak detection equipment, further enhancing safety.

While other options like frequent cleaning of the burner, adjusting the gas flow, and checking the appliance age can contribute to overall appliance maintenance and longevity, they do not directly guarantee adherence to safety limits in the same comprehensive manner as regular inspections and leak testing do.
