What is the term for the air that mixes with flue gases in a draft hood?

The term for the air that mixes with flue gases in a draft hood is dilution air. This air plays a crucial role in the overall ventilation and safety of gas appliances, as it helps to reduce the concentration of harmful gases before they are expelled into the atmosphere.

In a properly functioning draft hood, dilution air mixes with the flue gases to lower their temperature and improve dispersal, ultimately aiding in the efficient operation of combustion appliances. The introduction of dilution air ensures that the gases venting outside are less concentrated and are safely released, thereby minimizing the potential risk of harmful emissions re-entering the living space. Understanding the function of dilution air is essential for maintaining safety and compliance with ventilation requirements in propane gas systems.
