System Design Guidelines

•Inline grease exhaust fans should be installed near the end of the duct run to reduce sound at the hood.

•Inline fan must be securely bolted to the exhaust duct per NFPA-96 guidelines. Greenheck’s companion flanges are recommended for ease of installation.

•Grease exhaust fans and ductwork must maintain 18 inches (46 cm) minimum clearance to combustible material. If the ductwork and fan are insulated, the inspection door must be accessible for maintenance.

•A minimum of 10 ft. (3.0 m) of clearance must be kept from the fan outlet to adjacent buildings, property lines, or the closest point of any air intake or operable window at or below the plane of the exhaust termination.

•Greenheck recommends that all inline grease applications be reviewed by your local code official to ensure compliance with NFPA, IMC, and other local codes.
