According to NFPA 82, which type of equipment must be vented?

Venting is crucial for certain types of equipment to ensure that gases produced during operation are safely expelled from the building. Incinerators are specifically required to be vented as they operate at high temperatures and produce combustion gases that can be hazardous if not properly exhausted. This is outlined in NFPA 82, which focuses on the safe operation of incinerators, highlighting the need for ventilation systems to manage emissions effectively and to protect both the occupants of the building and the environment from harmful byproducts.

Other equipment listed, such as commercial-type ovens, residential water heaters, and gas fireplaces, may have different safety requirements and standards that do not necessitate the same kind of venting as incinerators. Therefore, while they also need to be installed and used safely, the specific requirement for venting aligns directly with the operation of incinerators as dictated by NFPA 82.
