Why is sufficient ventilation critical when using gas appliances?

Sufficient ventilation is critical when using gas appliances because it ensures there is an adequate supply of oxygen for the combustion process. Without enough oxygen, gas appliances might not operate efficiently, leading to incomplete combustion. This can produce harmful gases such as carbon monoxide, which can accumulate in the living space and pose serious health risks.

Additionally, proper ventilation helps to disperse these harmful gases, preventing them from building up to dangerous levels. Adequate air exchange is essential not only for the efficiency of the appliance but also for the safety of the occupants. This concept underscores the importance of maintaining a balanced environment where gas appliances can function correctly while ensuring that users remain protected from potential hazards associated with gas usage.
