What are the consequences of failing to ensure the required air to gas ratio?

Failing to ensure the required air to gas ratio can result in dangerous operation and potential explosion due to improper combustion. An incorrect air-to-gas ratio can lead to incomplete combustion, where not enough oxygen is present for the gas to burn fully. This can produce dangerous byproducts, such as carbon monoxide, which is highly toxic. In extreme cases, excessive gas accumulation can create an explosive environment, especially in confined spaces. The need for an optimal air-to-gas ratio is fundamental for safe and efficient operation of gas-burning appliances. Therefore, maintaining the correct mixture is critical to prevent not only performance issues but also life-threatening hazards.
