Build an exhaust fan belt and hinge-kit maintenance schedule for a commercial kitchen exhaust system

Steps

1. Pull the manufacturer's operation and maintenance (O&M) manual for the specific fan model, since belt tension, replacement interval, and hinge-kit servicing steps are manufacturer- and model-specific rather than set by NFPA 96 directly
2. Align belt/hinge servicing visits with the broader system inspection cadence already established for the kitchen (tied to the cooking-volume category) so a technician is on the roof/site at consistent intervals rather than creating an unrelated separate schedule
3. Confirm hinge mechanisms and hold-open retainers are exercised (opened, inspected, closed and secured) at each service visit so they don't seize from grease/weather exposure between cleanings
4. Inspect belts for glazing, cracking, and proper tension at each service interval, and replace proactively rather than only after failure, given the fire-risk consequences of an exhaust fan going down while cooking equipment remains in use
5. Log each service event (date, findings, parts replaced) to support both warranty requirements and AHJ documentation requests
