Which appliances are NOT required to have venting?

Counter appliances are typically designed for localized cooking tasks, such as electric grills or portable propane stoves, and are often utilized in outdoor settings or areas with adequate ventilation. These appliances are built to operate safely without an exhaust vent because they are meant to be used in open spaces, where any combustion byproducts can dissipate safely into the atmosphere. They usually don't produce the same level of harmful exhaust as larger, permanently installed appliances like furnaces or water heaters, which necessitate proper venting to ensure safety and prevent the accumulation of dangerous gases indoors. This distinction highlights why counter appliances are not subjected to the same venting requirements as other types of gas-fired equipment.
