What should be installed with a natural draft appliance affectively in a confined space?

A duct fan
A larger exhaust vent
An air supply opening
An additional heater

The correct answer is: An air supply opening

The installation of a natural draft appliance in a confined space requires proper ventilation to ensure that the appliance operates safely and efficiently. An air supply opening is essential because it provides the necessary combustion air for the appliance. Natural draft appliances rely on the principle of buoyancy, where hot gases rise and create a draft that pulls in fresh air for combustion. In a confined space, the air supply may be limited, which can lead to improper combustion and the potential for dangerous conditions, such as carbon monoxide buildup. By installing an air supply opening, you enable the appliance to draw in the right amount of air needed for safe operation. This ensures that the combustion process can occur correctly and reduces the risks associated with inadequate ventilation. Therefore, ensuring a proper air supply is not only a safety requirement but also crucial for the efficient functioning of the appliance.
