In the case of a gas heater with a water heater blanket covering the burner, what should be noted during an inspection?

A gas heater with a water heater blanket covering the burner should raise immediate safety concerns. The primary function of the blanket is to improve energy efficiency by retaining heat; however, if it completely covers the burner, it can obstruct the necessary airflow required for safe operation. This can lead to potential overheating and even create a risk of fire or hazardous gas accumulation. Therefore, it is crucial to note that having such a blanket covering the burner is not allowed due to these safety implications. This safety standard helps ensure that gas appliances operate effectively and reduce the risks associated with fire hazards or carbon monoxide leaks.
