The **NFPA 96**, which outlines the standard for ventilation control and fire protection of commercial cooking operations, specifically addresses the requirement for upblast fans to have hinge kits to facilitate inspection and cleaning. According to **NFPA 96 (2021 Edition)**, section **8.1.1.1**, it states:
“Approved upblast fans with motors surrounded by the airstream shall be hinged, supplied with flexible weatherproof electrical cable, and service hold-open retainers, and shall be listed for this use.”
This requirement is in place to ensure that upblast fans can be easily opened, inspected, and cleaned without disconnecting the electrical system or removing the fan entirely. The hinge kits allow the fan to be safely tilted for maintenance, ensuring compliance with fire safety standards. Having a hinge kit also helps prevent the accumulation of grease and debris in the fan and ductwork, which can become a fire hazard if not properly maintained.
