Exhaust Fan Hinge Kit

NFPA 96 Code 8.1.1.1 states: “Approved up-blast fans with motors surrounded by the air stream shall be hinged, supplied with flexible weather proof electrical cable and service hold-open retainers, and listed for this use.”

Trying to remove a heavy exhaust fan from its duct for cleaning or maintenance is not only dangerous for the contractor but always causes some degree of damage to the roof or the fan housing.

Exhaust fan wiring is stretched when the fan is taken off the stack and placed on the roof. Without a hinge kit, the fan wiring is subject to unnecessary abuse during cleaning and maintenance.

The exhaust fan can be damaged over time by removing it from the stack repeatedly and placing it on its side.

To prevent Rooftop damage and leaks can be the result of placing the exhaust fan on the roof during cleaning or maintenance.
It’s the Law!

AE Exhaust – Kitchen exhaust cleaning (often referred to as hood cleaning) is the process of removing grease that has accumulated inside the ducts, hoods, vents of Kitchen exhaust systems of commercial kitchens. Left uncleaned, kitchen exhaust systems eventually accumulate enough grease to become extreme fire hazards. Kitchen exhaust systems must be inspected regularly, at intervals consistent with usage, to determine whether cleaning is needed before a dangerous amount of grease has accumulated.
