In which location is it prohibited to install gas appliances?

Installing gas appliances in enclosed or unventilated spaces without proper safety measures is prohibited due to the significant safety risks involved. Gas appliances require adequate ventilation to ensure that harmful gases, such as carbon monoxide, can safely escape into the atmosphere rather than accumulating in the space where people may be present. Inadequate ventilation can lead to dangerous situations, including poisoning or fire hazards. Safety measures such as proper ventilation, carbon monoxide detectors, and adherence to local codes are essential for the safe operation of gas appliances. Thus, it is critical to avoid installing them in enclosed or unventilated areas to protect the health and safety of building occupants.
