Core Points - The article emphasizes the importance of safely using gas wall-mounted boilers, especially as temperatures drop, highlighting potential safety hazards associated with improper use [1][2]. Group 1: Safety Risks - Inadequate combustion of gas can produce carbon monoxide, a toxic gas that poses serious health risks if not properly vented [2]. - Carbon monoxide is described as an "invisible killer," being colorless and odorless, making it difficult to detect [2]. Group 2: Prevention Measures - Proper installation of a dedicated flue that extends outdoors is crucial to prevent gas leaks [3]. - Regular checks of the flue for damage, blockages, and secure fittings are necessary to ensure safe operation [3]. Group 3: Pre-Usage Checks - Before starting the boiler, it is essential to check for gas leaks using soapy water on connections, ensuring no bubbles appear [5]. - The pressure gauge should read between 1 bar and 1.5 bar; adjustments may be needed if the pressure is too low or too high [5][6]. Group 4: Usage Guidelines - Users should maintain power to the boiler during the heating season, even when the house is unoccupied, to prevent pipe freezing [8]. - Good ventilation in the room where the boiler is installed is critical, and it should not be placed in bathrooms or sealed spaces [9]. Group 5: Emergency Procedures - In case of suspected gas leaks, immediate actions include shutting off the gas supply and avoiding any electrical devices or open flames [14]. - If the boiler malfunctions, users should consult the manual for error codes and refrain from self-repair, contacting professionals instead [14]. Group 6: Maintenance Recommendations - Regular maintenance every 1-2 years is advised to clean components and check operational efficiency, which can enhance safety and reduce gas costs [16][17].
