How much horizontal clearance must rooftop terminations provide from the outlet to adjacent property lines and air intakes?

The requirement for rooftop terminations to maintain horizontal clearance is essential for ensuring that exhaust emissions do not negatively impact adjacent properties or air intakes. The standard specifies that a distance of 10 feet must be maintained from the outlet of the exhaust system to adjacent property lines and air intake areas. This distance is crucial for allowing proper dispersion of exhaust gases, minimizing the risk of nuisance or health hazards to neighboring buildings and occupants.

Maintaining this clearance helps mitigate the potential for odors, smoke, or other contaminants from the cooking operations affecting areas where fresh air is drawn in, as well as ensuring compliance with local zoning and air quality regulations. This specificity is grounded in safety principles that align with NFPA 96 standards. Understanding these requirements is vital for anyone involved in the design, installation, or maintenance of commercial kitchen ventilation systems.
