What is the purpose of dilution air?

The purpose of dilution air is to enhance combustion within propane appliances. When propane is burned, it requires a certain amount of oxygen to ensure complete combustion. If there is insufficient oxygen, it can lead to incomplete combustion, which results in the production of harmful emissions such as carbon monoxide. By introducing dilution air, the overall air-fuel mixture is improved, allowing for more efficient burning of the fuel. This results in cleaner combustion and reduced emissions.

While reducing emissions is a beneficial outcome of adding dilution air, the primary function itself is more about ensuring adequate oxygen is available for complete combustion, which in turn facilitates the reduction of harmful emissions. Cooling appliances can also be a secondary effect, but the main intent is to optimize the combustion process. Facilitating air movement is important in ventilation systems, but does not specifically address the combustion efficiency of propane gas.
