Core Viewpoint - The article emphasizes the importance of replacing gas stoves that have exceeded their service life, typically not exceeding 8 years, to prevent safety hazards such as gas leaks and carbon monoxide poisoning [2][6]. Group 1: Replacement Criteria - Gas stoves and water heaters have a clear service life, generally not exceeding 8 years from the date of sale [2]. - Four indicators to determine if a gas stove needs replacement include: 1. Functionality issues such as frequent extinguishing of flames or inconsistent water temperature from the heater [2]. 2. Condition of the flame; a blue flame is normal, while black smoke or a pungent smell indicates a need for immediate replacement [2][3]. 3. Physical appearance; any deformation or severe rusting of the stove should prompt immediate replacement [2]. 4. The effectiveness of the flame extinguishing protection device should be regularly checked [3][4]. Group 2: Safety Recommendations - Regular cleaning of gas stoves is essential to prevent blockage of gas holes, nozzles, and fire caps, which can affect normal combustion [6][8]. - Avoid using incompatible energy-saving products like "energy rings" or "wind shields," as they can cause damage and lead to incomplete combustion, producing harmful substances [7]. - Regular inspection of gas connection hoses is necessary to prevent aging, breakage, or damage, ensuring compliance with safety standards [7]. - Maintaining a stable gas usage environment is crucial; ensure proper ventilation while avoiding direct strong winds that could disrupt combustion [8].
