Examples of vented appliances include:

Vented appliances are designed to expel combustion gases outside the living space to ensure safety and efficiency. Water heaters and fireplaces exemplify vented appliances because they rely on a venting system to carry away byproducts of combustion, such as carbon monoxide and other harmful gases, preventing them from entering the indoor environment.

In the case of water heaters, they typically use a flue to vent exhaust gases produced during the heating process. Fireplaces, depending on their type, often have chimneys or vent pipes that allow smoke and gases to exit the building safely.

In contrast, gas stoves and electric heaters do not typically require venting as electric heaters do not produce combustion gases, and gas stoves can sometimes operate without direct venting, relying instead on the space's overall ventilation. Portable propane heaters generally do not feature extensive venting systems, and wall-mounted electric units do not produce combustion gases at all. Thus, choices that include appliances not requiring or designed for venting are not suitable examples of vented appliances.
