A draft hood will:

Increase the combustion temperature
Prevent a downdraft from entering the appliance
Exhaust flue gases directly outdoors
Enhance flame stability

The correct answer is: Prevent a downdraft from entering the appliance

A draft hood plays an essential role in the proper functioning of gas appliances by managing the flow of combustion gases. Its primary purpose is to prevent the reversal of air flow, particularly down drafts, which can lead to the dangerous backdraft of flue gases into the living space. By creating a balanced pressure condition, the draft hood helps ensure that the combustion process is efficient and safe, allowing for the proper venting of any combustion byproducts. This functionality is crucial because it protects the appliance from being negatively impacted by unwanted airflow changes, which can disrupt safe operation. Ensuring that the appliance operates with an adequate supply of air is key to maintaining combustion efficiency and preventing hazards associated with flue gas accumulation, such as carbon monoxide poisoning. Therefore, saying that it prevents a downdraft from entering the appliance accurately reflects its vital safety and operational role in gas fitting.
