How far must the termination of chimney or vents equipped with power exhausters be from the lot line or adjacent buildings?

The termination of chimneys or vents that are equipped with power exhausters must be located at least 10 feet from the lot line or adjacent buildings. This requirement is rooted in safety concerns, particularly regarding the potential for harmful exhaust gases to enter neighboring properties or facilities. The 10-foot distance helps ensure that the discharged fumes and pollutants are effectively dispersed and do not negatively impact air quality in areas where people live or work nearby.

This minimum distance is established to reduce risks associated with the concentrated release of combustion products, which could include carbon monoxide and other hazardous substances. By adhering to this regulation, one is following code provisions designed to promote safe ventilation practices and protect public health. Correctly complying with this aspect of the mechanical code is essential for maintaining an appropriate safety standard in building design and installation of mechanical systems involving power exhaust.
